Combust

You speak a word, causing your targets to spontaneously burst into flame. Choose up to 5 targets within range. Each target must make a Dexterity saving throw. On a failure, each creature is set on fire and takes 6d6 fire damage, or half as much damage on a success. A creature on fire takes an additional 1d6 damage at the start of its turn, unless it uses an action to put it out.

At Higher Levels. When you cast this spell at 6th level or higher, you may target an additional target for each level above 5th.
