Incendium

You release a pulse of infernal energy that spreads as a 150-foot-radius sphere centered on you. Creatures in the area must make a Constitution saving throw. On a failure, an affected creature takes 12d6 incinerating damage and becomes Scorched, taking 4d6 incinerating damage per turn. On a success, it takes only half the damage. A creature Scorched this way can only remove the condition through magical water or the remove curse spell.

Creatures already Scorched have disadvantage on this saving throw, and on a failure, they also become Stunned until the start of their next turn.
