dancing blaze

A Fiery cloud of heat and flammes flies torward a creature within range and surrounds it with fire. At the end of it's turns, the surrounded creature needs to make a constitution saving throw or take 2d8 Fire damage, on a success it only takes half as much.

On your turn, you can recast this spell as an action targetting a creature within 15ft of the original to surround it. The original creature is no longer affected by the spell. If a creature dies with the spell on it, you can use a reaction to surround a creature withing 15ft. If nothing is in range then the spell ends early.

At Higher Levels.  When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
