1st-level abjuration


Casting Time: 1 action

Range: Self

A protective magical force surrounds you, manifesting as a spectral frost that covers you and your gear. You gain 5 temporary hit points for the duration. If a creature hits you with a melee attack while you have these hit points, the creature takes 5 cold damage.


At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, both the temporary hit points and the cold damage increase by 5 for each slot level above 1st.


All information about Armor of Agathys 5e comes from the DnD Player's Handbook.

Armor of Agathys 5e

Classes That Can Cast Armor of Agathys 5e

Surprisingly, the only class in the Player's Handbook that may cast Armor of Agathys is the warlock. Through other game expansions, players may access a sorcerer and paladin subclass, along with the mark of warding dwarf, who may also cast the spell.



Armor of Agathys Spell Effectiveness

Calculations for Healing and Damage

Note that Armor of Agathys only provides temporary hit points, not actual healing. Furthermore, the cold damage dealt by Armor of Agathys only activates so long as the temporary hit points provided by the spell are still active. Finally, note that the DPR (damage per round) provided in the third row is a very rough, estimated calculation of damage, before factoring in the attack's hit chance - in an effort to best provide direct comparison of value.


Armor of Agathys Usefulness

Armor of Agathys 5e is both a temporary healing and damage spell. Players should use Armor of Agathys in the following circumstances:

  • Ideally, before any battles begin. Since Armor of Agathys 5e has a 1-hour duration, it's best used before danger shows up, to provide more actions during combat for casting other high-priority spells.
  • When fighting enemies with melee attacks. Since Armor of Agathys only deals cold damage to melee attackers, the spell loses half of its value against other spell casters or enemies who attack from a ranged distance.
  • Against enemies with cold vulnerability, to maximize damage dealt.
  • Against enemies who deal high amounts of damage. Healing after taking damage is a reactive approach to combat, whereas Armor of Agathys 5e proactively increases hit points in anticipation of difficult battles.
  • As a way to make a fragile (especially spell caster) character more durable.

Combine Armor of Agathys 5e with the Following Spells

Even though Armor of Agathys 5e admittedly has critical limitations to its effectiveness in certain circumstances, it can still be combined with other key spells to considerable effect:

  • Bless 5e: the bless spell has limitations of its own, though it does provide provide a +1d4 bonus to saving throws. Basically, since it reduces spell damage, it's useful to have in addition to the temporary hit points provided by armor of agathys.
  • Cause Fear 5e: since Armor of Agathys is intended to protect characters during battle, or dissuade enemies from attacking, cause fear can be a great supplement. If cause fear fails or its effect fades, then Armor of Agathys is still in place to help keep characters alive against enemy aggression.
  • Charm Person 5e: similarly, charm person may be used to prevent an enemy from attacking. Should the spell fail or its effect end, having a backup defensive spell is always valuable.
  • Cure Wounds 5e: if the temporary bonus hit points from armor of agathys get reduced and a character takes damage, having additional healing is always helpful.
  • Haste 5e: as with the bless 5e spell, haste provides additional protection in the form of +2AC, doubled movement speed, and advantage on Dexterity saving throws. The extra hit points from armor of agathys can help keep hasted characters alive even longer, particularly against difficult foes. 
  • Mage Armor 5e: consider mage armor a lesser version of the haste spell, effectively giving targets +3AC (depending on character builds, etc.). The more hit points a character has - such as from armor of agathys - the more time that bonus AC has to reduce damage taken.


Players should also be aware that temporary hit points cannot stack in DnD 5e. That means spells such as Aid 5e cannot give characters additional hit points, if they're already affected by spells or effects such as armor of agathys 5e.


Armor of Agathys 5e Counters

In all reality, armor of agathys 5e has lots of counters, making it probably a mid-tier spell at best. Though effects like Silence 5e can't be used to directly counter armor of agathys (in most cases) since the spell will probably most often be used prior to battle, there are still other options.


For example, the cold damage from armor of agathys only takes place if the attack that hits them is melee, and before the temporary hit points granted from the effect are depleted. So, if a character with armor of agathys is attacked from range - like with a bow and arrow, or spell - then no cold damage is dealt. Similarly, if melee characters just wait to attack a target who's benefiting from armor of agathys until those temporary hit points are somehow removed, then there's no danger of taking cold damage.


Finally, the biggest "counter" to armor of agathys is to actually deplete the temporary hit points. Consider spells like mage armor, for comparison. Mage armor's bonus to AC doesn't ever go away, at least until the spell's effect ends. So, if the character takes damage, then gets healing, mage armor is still fully in effect. Meanwhile, as soon as 5-damage per spell level is dealt to a character with armor of agathys, the effect fades. Healing doesn't "return" the effect, or provide more value. Basically, it's just about the easiest spell in the game to completely negate.

Armor of Agathys-Type Spells in Eternity TTRPG

I feel like most all great RPGs, whether they're a TTRPG or video game have some kind of frost shell. Which, you can imagine, is basically what comes to mind for me with armor of agathys.


In the Eternity TTRPG Game System - a tabletop game like DnD - there are several spell effects similar to armor of agathys. Below is one such example, which is probably the most similar type of spell.

Cryomancer Class Icon

Cryomancer - Core Class Spell

Glacial Shell (Magic): you are resistant to cold, and immune to ice damage (including ice damage from other cryomancers). Also, anyone who melee attacks you, roll +7Faith vs. Resilience, gives -2Speed for 1turn. “Glacial Shell” cannot Double-Hit or give a Block. Once this Spell is chosen it becomes a passive effect, always active, and cannot be dispelled.

  • (Frost Knight) You can now cast this Spell on other targets. You can instead choose to continually maintain this Critical for 1Inspiration (and 0Wisdom), per target other than yourself.
  • (Spells of Everwinter) You also gain +3Resilience, +3Dodge, and +3Will. You can instead choose to continually maintain this Critical for 3Inspiration (and 0Wisdom).
  • (Elemental Ice) Gives -4Speed for 1turn. You can instead choose to continually maintain this Critical for 1Intelligence (and 0Wisdom). 


Though Glacial Shell doesn't deal damage, but rather lowers enemy Speed, it also only affects melee attackers. Similar to armor of agathys 5e though, it's also cold-themed, and intended to provide protection to the spell caster or their target(s). If used as a Critical, this spell can provide substantial protection either against melee attackers, or even against any attacking enemy.

The New Final Fantasy TTRPG Is Here — And It’s Incredible

By Jacob Tegtman • December 12, 2025
Transcribed content from our recent YouTube video: https://www.youtube.com/watch?v=1GBbHsUFBR8 Transcription Visit the Final Fantasy Tabletop Roleplaying Legend Edition Website . Final Fantasy fans… it’s finally happening. A brand-new tabletop RPG built specifically to capture the tactical, job-swapping, limit-breaking chaos we love from the Final Fantasy series. But… for those of you who are familiar with Final Fantasy d20, and other predecessors to this Legend Edition, why make a whole new system when Final Fantasy Tabletop RPGs have already existed in the past? And what makes the Final Fantasy Legend Edition so special? Today, we’re diving in to the game that aims to become the definitive way to play in Ivalice—or any Final Fantasy world—at your table. Oh, and did I mention that this is a professionally-designed game book and PDF assets for every conceivable part of your game – and it’s all 100% free? That’s right, free. This is a passion project brought to you by Mildra the Monk and his amazing team that they’ve been working on for years. It’s absolutely incredible what they’ve put together, and you can get it for your table today – at no cost. Hey everyone, welcome back to ETTRPG—your home for tabletop news, deep dives, and world-building inspiration. If you love Final Fantasy, Tactics-style combat, or job systems with way too many builds to ever be able to properly enjoy it all, today’s video is for you. So, Final Fantasy TRPG: Legend Edition is a spiritual successor to the long-running Returners’ Final Fantasy RPG and its offshoots like Final Fantasy 4e and Omega Fantasy. But this isn’t just a rehash—this is a completely modernized, research-driven rebuild of the whole system. The devs, among them Mildra the Monk, who has been a big supporter of us at Eternity TTRPG for years, spent three years dissecting the games, the lore, the combat, and all the unique systems that Final Fantasy fans love. The result? An intermediate-complexity tabletop RPG laser-focused on recreating the true Final Fantasy experience – at the table—without any confusing crunch, or decade-old legacy rules. Ok, as I mentioned, there are other Final Fantasy tabletop systems already. But here’s what it boils down to for why it was worth it for Mildra and his team to create this new system. Number one: Simplicity None of the previous games fully capture the mythos of Final Fantasy while still giving players complete setting freedom . Where earlier systems often tied you to a specific world, tone, or era, Legend Edition was built around a single core design principle, which is: “Mythos over setting.” This means the rules capture the soul of Final Fantasy—Summons, Jobs, elemental affinities, cinematic abilities—but they don’t lock you to Ivalice, Gaia, Spira, or any one timeline. Using this game system, you can: Recreate your favorite Final Fantasy world. Mash up multiple games. Or build your own world entirely from scratch. This is FF energy, but not FF rails , that makes it such a big deal. So, moving on, What Makes Legend Edition Stand Out? The first piece is: Ridiculously Modular Character Building. In the future, I plan to do more videos on Final Fantasy Legend Edition. But let’s content ourselves today by summarizing – at least for this section – that there’s 50+ Jobs drawn from across the franchise. Included are fan favorites and long-time classics such as Dragoon, Black Mage, Thief, Time Mage, Gunbreaker, and dozens more. Using these 50+ Jobs, you do in fact have over 25,000 job combinations available to you, as a player. And these aren't “same-y” class splashes. The track-based advancement system makes each mix feel meaningful, distinct, and highly customizable. Oh—and there are 14 playable races taken from the Final Fantasy universe , each with their own unique ability. This is one of the most flexible JRPG-inspired character engines out there. The second big item that makes the Legend Edition Stand Out is Streamlined, Row-Based Combat, like your favorite Final Fantasy games from back in the day. Legend Edition offers an easy-to-learn row-based combat system that keeps the spirit of classic Final Fantasy battles while speeding everything up. You still get things like: Elemental affinities, Status effects, Skills with cinematic alt uses, And powerful Limit break moments. But, the math is way smoother than you’d expect. You won’t need a calculator, like if you took Final Fantasy I directly to your table. Next up is that the book provide you with Mythos-Driven Campaign Systems. Final Fantasy stories, across all games even back to the originals, are political. Big factions, world tension, and meaningful alliances are core to the franchise. Legend Edition builds this directly into play with: A Reputation & Affiliation system . You also have what’s called “The Holdings system” to build your very own base. The game comes with expanded NPC creation rules, and a robust Skill Game system for non-combat set pieces. This is the stuff that makes your campaign feel like a Final Fantasy game, not just another “game like D&D,” but with a “Final Fantasy” sticker slapped on their for flavor. As if all of the core game’s features are not enough, The Expansion Books Are pretty Wild. The Ultimania Expansion adds: 28 new races , 4 new jobs , 300+ sample items , Airship & Mecha creation systems , plus More Skill Games and Affiliations. Meanwhile, the Enemy Intel Field Guide brings you 200 full NPC stat blocks , a Fully detailed bestiary, and Drop-in encounter prep tools. Basically, everything you need as a Dungeon Master to prep your game with maximum Final Fantasy feel, and minimal effort. Additionally, if you want to run FF Tactics, FFIX, FFX, or even a fully original world—these books give you all the toys for each of those specific settings. Wrapping it all up, Legend Edition emulates the cinematic spirit of Final Fantasy with its Big narrative beats, Cutscene-worthy skill moments, Dramatic faction politics, Summons that feel truly mythic, and Job classes that are meaningful extensions of character identity. If you’ve ever said “I wish Final Fantasy had a premier tabletop version,” this is the game you need to try out at your table, next. So, if you’ve made it this far, I think you and I both know it’s time for you to download your free copy of Final Fantasy Legends Edition. I’ve got that link in the video description below. But I want to hear from you: what do you think? Does Legend Edition finally deliver that top-quality Final Fantasy tabletop experience we’ve all been waiting for? And if so, what will be the first Job class you’ll try out? Let me know in the comments. Hit like, subscribe, and share this video with your party. Let’s get Mildra and his team the recognition on this masterpiece that they truly deserve. Until next time—may your crits be big, and your summons be even bigger.

Relicborn — The Blue-Boned Swashbuckling Undead of Crooked Moon

By Jacob Tegtman • December 6, 2025
Transcribed content from our recent YouTube video: https://www.youtube.com/watch?v=RwDiy7u-wUo Transcription In Kalero, the canyon walls sing.  Not literally — but if you listen closely, as the desert wind slips through the stone crypts and carved tombs, you’ll hear something. A rhythm. A pulse. A beat. And when the Crooked Moon dips behind the cliffs, figures begin to emerge — their bones glowing with blue light, their skulls crowned with curls or braids, their steps half-dance, half-swagger. These are the Relicborn — the living memories of Kalero. Dressed in vibrant fabrics, lacquered patterns, and sometimes… a flashy swashbuckler’s cape or rapier at their side. Today on Eternity TTRPG, we’re diving into one of the most joyful, most soulful, and most stylish ancestries in all of Druskenvald. Crooked Moon continues to be one of my favorite adventure supplements of all time, and you can pick it up on D&D Beyond. Whether you’re a player wanting a character with flair, you’re a DM craving new cultural flavor for your campaign, or you’re just a lore-nerd who loves stylish undead — this one’s for you. The Relicborn are a species native to Kalero, a province lined with towering canyon walls carved into catacombs and mausoleums. But despite being born from tombs, they are anything but gloomy. These are living skeletons , decorated with any number of colors, hand-painted motifs, and glowing patterns. Their bones are encased in a translucent magical substance that gives them full humanoid shape. And if your Relicborn wants big curly swashbuckler hair? Yes. They can actually grow it from their skulls. Where they come from is unique: they’re formed in the crypts of Kalero, rising from ancestral memory and celebratory magic rather than necromancy. Theirs is not a culture of undeath — it’s a culture of joy , reflection , and honoring the past through celebration. Every Relicborn is essentially a walking festival — a living memory kept alive through music, dance, and stories. Relicborn society is built on a delicate balance: the energy of a vibrant celebration and the quiet reflection of ancestral remembrance. Imagine communities built along canyons, with lantern-lit walkways leading into ancient tomb-shrines. Families gather at night to play music, tell stories, and dance under blue and purple moonlight — while their ancestors' spirits look on. Their festivals can last days. Their moments of silence last just as long. They thrive in community — in the stories of who came before, and who they themselves will become. Relicborn live roughly 250 years , and when their time ends… they simply collapse gracefully into a pile of bones, returning to the crypts that first birthed them. All of the fun roleplaying stuff aside, let’s break down how their mechanics reflect their culture, starting with the most signature ability: Dance of Death As a bonus action, you make a DC 15 Charisma Performance or Instrument check. If you succeed, your next attack roll this turn has advantage . If you succeed by 5 or more? You roll one of your Hit Dice (without spending it!) and gain temporary hit points . This is perfect for swashbucklers, bards, rogues — anyone who wants to flavor combat like a deadly dance. Next, they have: Eternal Party Relicborn don’t sleep. Instead, they complete a long rest in four hours so long as they spend it in revelry — music, storytelling, gentle dancing, or shared celebrations. Imagine your party taking a rest and your Relicborn swashbuckler quietly jamming with a bone flute while keeping watch. This one’s pretty good: Moment of Remembrance When a creature you see within 30 feet fails a d20 test, you can use your reaction to add 1d4 to their roll. Once you turn a failure into a success, you can’t use it again until a rest. Relicborn are bursting with character potential. They have Incredible aesthetics. From glowing bones to swashbuckler outfits — you can lean into a Day-of-the-Dead style undead, a pirate, a festival style, or something Gothic. If you were to play a Relicborn… What would your glowing bones look like when you’re afraid, happy, or angry? And when your long life ends — what do you hope those you care about remember about you? Drop your ideas in the comments. And if you enjoyed this deep dive into the Relicborn, hit like, subscribe, ring the bell, and join me next time as we explore another Crooked Moon ancestry. Until then — Keep the music playing. Keep the celebrations bright. And may every memory lead you to your next dance.

Fateweaving in The Crooked Moon — Personalizing Story

By Jacob Tegtman • December 2, 2025
Transcribed content from our recent YouTube video: https://www.youtube.com/watch?v=Kl3c6djcgbo Transcription Imagine your character in a folk-horror saga — not just another adventurer, but someone with a personal fate, a hidden thread that drags them deeper into shadows and tragedy… or redemption. That’s exactly what Fateweaving brings to Druskenvald in The Crooked Moon. The Crooked Moon isn’t just another D&D book. It’s a 600-plus-page folk-horror campaign that plops players into a sun-starved realm of nightmares, rituals, and haunted rails. Welcome back to Eternity TTRPG, your home for deep-dive D&D news breakdowns, world-building insights, and tools to level up your tabletop storytelling. Whether you’re a forever-DM, a lore-monster, or someone who appreciates a well-crafted adventure, we tackle the big ideas behind the games you love. And today, as with many videos I’ve created over the past several months, The Crooked Moon gives us plenty to sink our teeth into. What sets Crooked Moon’s System apart from the standard “roll dice, then fight monsters” is the optional system called Fateweaving — a way to bind each character’s past, motivations, and desires directly into the core of the campaign. Fateweaving gives each character a Thread of Fate — one of 13 possible personal arcs. At character creation (or early on), each player picks a Thread that defines a personal goal: lost memories, cursed lineage, spiritual duty, monstrous ambition — you name it. Then, throughout the campaign’s story, the GM weaves in six Narrative Touchpoints specific to that Thread. These form a full character arc , culminating in a personal climax and catharsis that runs parallel to the main story – they’re something much greater than just “side quests.” The first touchpoint, Incitement , ties a character’s personal quest to the campaign’s opening (often aboard the spectral Ghostlight Express or within the Crooked House). As the story progresses, the character meets allies or NPCs connected to their fate, uncovers secrets, faces a personal trial, then pushes through to their own climax — all while the main horror unfolds. In the end, during the epilogue, each character receives Catharsis — the emotional and narrative payoff for their arc. This means every player is actively living their own horror-tale inside the larger one of your full campaign. You might ask: why bother with all this Fate Weaving stuff? It does add potential complexity to your campaign, after all. So why not just run a normal campaign? It’s because Fateweaving transforms The Crooked Moon – or, any campaign you’re running –into a deeply personal story, for the players. It gives each character agency and meaning — their choices and their backstories matter. It increases emotional engagement for players : horror, hope, tragedy — when stakes are personal, every failure and every success resonates. It helps GMs balance player spotlight : with distinct Threads, you can weave in scenes tailored to each player without derailing the main plot. For players who love roleplay and character development — this is the sweet spot. Let’s pick an example Fateweaving Thread — say the Thread of Deliverance – and run through it really quick, just to give you an idea for how this works. The character begins lost, ejected from the spectral train, given only a broken compass. (this is the “Incitement” step) Later, at a trading post, a shady merchant hints he knows of strange artifacts. (this then, is the “Connection” step) On a creepy riverboat, the character recovers the first piece of a broken family heirloom. (with the “Discovery” step) In a haunted cemetery sanctuary, they wrestle the second piece from a statue’s grasp. (the “Confrontation” step) After the final boss — the Crooked Queen — they reclaim the last piece, reforge the heirloom, and choose either to become a ferryman of souls… or walk away free. (culminating in the “Climax + Catharsis” step) Suddenly, your campaign isn’t just “we stopped the big bad.” It’s the players’ story. Their redemption. Their choices. And in this case – even their soul. If you want to try out Crooked Moon’s Fateweaving system, here’s some very easy ways to get started: L et your players pick Threads early in the campaign – or, if you’re already running one, let them pick at your next session – then collaborate to weave their backstories into the world you’re running. Keep the Touchpoints flexible: treat them as narrative prompts — adapt to what your players do rather than forcing them. Be generous with spotlight time: Fateweaving only works if each character actually plays their arc, and gets to express their character through each important moment. Use Touchpoint rewards to drive engagement: use boons, stat bonuses, and narrative closure — they reinforce the importance of the arc. Don’t be afraid to deviate: mix endings, merge threads, or create custom ones — Crooked Moon’s Fateweaving system is meant as building blocks for you, not a cage you have to live in. If you run your next horror campaign in Druskenvald — or any other world where Crooked Moon’s spooky setting fits — consider using Fateweaving. It’s not just good for story… it’s the kind of DM fuel that turns players into protagonists, and campaigns into personal sagas . That’s it for today!
