In the process of promoting silly party feats and a cantrip to support one of those feats, I designed:
Range: 30 ft
Casting time: 1 action
Components: S, V
Class: Bard, Warlock, Wizard
You point one of your fingers in a direction away from you. A stream of confetti bursts forth to a point within 30' of you, lightly obscuring a volume no larger than a 5' cube for 1d4 rounds. You can have two of these effects present at any one time.
The confetti is flammable: mundane fire (torches, matches, burning tapers, candles, etc) and spells such as fire bolt that set fire to flammable materials burn the confetti away and in so doing cause 1d4 fire damage. This fire damage is increased to 2d4 at 5th level, 3d4 at 11th level, and 4d4 at 17th level.
Like vicious mockery, it has two different effects, but it isn't a powerful damage dealer. In order to do damage, either the bard or the ally must take a subsequent action. The opportunity for accidental damage is certainly present.
Is this cantrip within the bound/constraints of cantrips in the PHB?
If not, what adjustment needs to be made to bring it into balance?
- The chosen volume is similar in size to minor illusion and shape water cantrips.
- The "something else catches it on fire" is similar to what happens to a web when a fire bolt, flaming sphere, or a fireball hits the webbed area.
- I was considering making this a bonus action cantrip, but I got the idea that an exploit like shoot confetti/firebolt as bonus action/action would be a 'too powerful' exploit and chose '1 action' instead.
- If I can get this cantrip right, I'll be adding it to the Wild Beyond the Witchlight adventure.
- I am not sure if the name wholly captures the cantrip; if a recommendation for a new name like "confetti cloud" or something else comes to mind when offering an answer, a better name would be appreciated but is not necessary to answering the balance question.
