Burning Flare

A pillar of flames erupt from you engulfing the surrounding area by flames. All creatures within range take 1d10 fire damage. This does not however, damage the caster. This leaves the area with flames that will only go out after about 4 minutes and cannot be put out by anything.

The damage increases by 1d10 at 6th level (2d10), at 12th level (3d10) and at 18th level (4d10).
