Chain of Fire

You hurl a mote of fire at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 3d10 fire damage. Upon a successful attack with this spell, the caster can target an additional target within 10 feet of the original target.  Damage is reduced by 1d10 each time this feature is used.  This feature may be used up to two times after the original attack succeeds.

A flammable object hit by this spell ignites if it isn't being worn or carried.
