Cloud of Daggers - D&D 5th Edition Spell Book

Classes That Can Cast Cloud of Daggers

The following classes from the player's handbook can cast cloud of daggers:

• Bard
• Sorcerer
• Warlock
• Wizard

Cloud of daggers is honestly a pretty strange spell. As you'll see below, it's not very powerful (nor does it make a lot of sense, in my personal opinion). Cloud of daggers seems more like something a bard player came up with one time, and then the spell somehow made it into the official game.

Otherwise, it's a little hard to imagine why any spell caster would create a literal cloud of what I imagine to be spinning daggers.

Cloud of Daggers Spell Effectiveness

Spell Damage

The table above compares cloud of daggers to burning hands 5e, a 1st-level evocation spell, and to a fighter's average damage per round. The biggest thing to note here is that cloud of daggers is not a ranged spell attack, and it doesn't require a saving throw. Instead, if a target begins their turn in the affected area, or moves through it, they automatically take damage. So, though the damage represented in the table above appears quite low comparatively, burning hands and the fighter's represented damage are calculated without factoring in hit chance, so their true values would be quite a bit lower in some cases.

Cloud of Daggers Usefulness

Cloud of daggers basically has two features that make it useful:

• The spell does not require a hit chance. Since it's neither a ranged spell attack nor requires a saving throw, when you cast the spell on a target, when that target begins their next turn, they automatically take damage.
• Furthermore, the spell can be maintained with concentration, meaning that you can cast the spell at a choke point, forcing enemies to walk through your cloud of daggers to get to you. If there is no such 5-foot sq. choke point in your environment, however, then this additional advantage disappears.

Since Cloud of Daggers does not require any kind of hit chance, you should cast the spell on enemies who:

• Have very high AC and are therefore resistant to spells such as chromatic orb and chill touch 5e.
• Have very high Dexterity saves and are therefore resistant to spells such as burning hands, call lightning 5e, and even cantrips like acid splash 5e.

If there happens to be a choke point on the battlefield such as a 5-foot wide tunnel, or perhaps a 5-foot wide bridge that enemies have to cross, cloud of daggers could actually be an amazing spell choice. If you can center cloud of daggers on an enemy, dealing damage, and then force others to either not pass through the cloud of daggers at all, or push past and take more automatic damage, then the spell could really shine.

Honestly, if you had some choke point with an area you were trying to defend for 1-minute or less (the spell's duration), cloud of daggers could actually work like an improved alarm 5e, as not only would you be alerted to enemies crossing through - via their screams of pain - but yes, you would also deal damage with your alert system.

Slashing Damage Resistances, Immunities, and Vulnerabilities

In the D&D monster manual there are 6-monsters with slashing damage resistance, only 2-monsters with slashing damage immunity, and 0-monsters with slashing damage vulnerability. Of all the damage types, slashing damage is one of the least resisted, and is pretty much secure as a good spell damage choice almost no matter what you're facing.

Combine Cloud of Daggers with the Following Spells

Most DnD spells have some kind of other spell type that they mix well with, whether they increase hit chance, give more actions, or increase defenses, etc. With cloud of daggers, I wouldn't really say that there are many directly beneficial support spells, though I suppose that there are a few that could work well together.

• Banishment 5e: say that you've cast banishment on an extra-planar enemy. Once the 1-minute spell effect from banishment is up, that being will be banished from your current plane for good - or that is, at least until they find a way back. In any case, if you can use cloud of daggers to protect an ally while they concentrate on banishment, this combination could make for a very successful combat encounter.
• Blindness Deafness 5e: this is a pretty mean combination, but imagine blinding an enemy, then casting cloud of daggers right in front of them. Since they're blind, chances are high that they could walk right into your spell. Of course, you could always just cast cloud of daggers right in their space to begin with, so blinding them isn't really necessary. But I imagine that being slashed by a cloud of daggers while blinded would be significantly more terrifying than the spell's usual effect.
• Cause Fear 5e: if your goal is to prevent enemies from attacking you - say especially if you have a choke point with cloud of daggers set up - then a spell like cause fear could also be helpful to use, especially against any ranged characters who wouldn't need to pass through cloud of daggers in order to attack you. Note, however, that since cloud of daggers in also a concentration spell, you'd need to coordinate cause fear with one of your other party members.
• Charm Person 5e: similar to cause fear, you could charm enemies with enough range or spells to avoid cloud of daggers.
• Spiritual Weapon 5e: since spiritual weapon can be moved away from you, and is immune to damage, you could cast cloud of daggers, then send your spiritual weapon after your enemies, beyond the choke point. Spiritual weapon is also a concentration spell, however, so an ally would need to cast this spell.

Cloud of Daggers Counters

So many spell effects are more or less nullified by the fact that cloud of daggers doesn't require a ranged spell attack or even a saving throw. However, as always, silence 5e is a nice choice to prevent the spell from ever being cast, in the first place. If you're charging into a choke point and you're facing a bard, sorcerer, warlock, or wizard, you can be sure that they're thinking about cutting off the choke point with cloud of daggers, so silencing them ahead of time could be a great move.

Additionally, the relatively useless cantrip blade ward 5e actually has some great value against cloud of daggers as it grants you resistant to slashing damage for 1-round. If you need to charge through a choke point that's covered by cloud of daggers, cast blade ward and run in. You'll certainly find yourself far better off than if you'd run through without the slashing damage resistance, that way.

Cloud of Dagger-Type Spells in Eternity TTRPG

Finally, I'll share a bit about the Eternity TTRPG Game System. I realize that you came here for information on cloud of daggers, but maybe you've been thinking about checking out other TTRPG systems. If that's the case, then I'll keep it short: Eternity TTRPG allows for multiple players to act as the game master at various times during your campaign. The game also features very fast-paced combat encounters, and every class/ character feels like it has something meaningful to contribute, while also being equally useful.

Below, I've included a sample spell for you that somewhat represents the general purpose of cloud of daggers. You can take a quick look to see if you like the game's flavor. If so, there are links below for where you can find the game.
