Enflame

Immense heat consumes your body as you become a conduit for the elemental plane of fire to manifest on the prime material plane. You become the epicenter for a writhing storm of fire bursting outward from you. On the turn you cast Enflame and each turn after that while you maintain concentration, you take 1d10 fire damage. In addition, each enemy within 10ft of you takes 6d6 fire damage, or half as much damage on a successful dexterity saving throw. Each turn you maintain concentration, the damage of the spell increases by 2d6 and the range increases by 10 ft.

When you cast this spell using a spell slot of 6th level or higher, the starting damage is increased by 1d6 to a total of 7d6 at 6th level, 8d6 at 7th level, etc. and the starting range is increased by 5ft to a total of 15ft at 6th level, 20ft at 7th level, etc.
