Adir's Agonizing light (do not use)

A bright streak flashes from you to a point you choose within range and then blossoms with a thundering roar in bright explosion. Each creature in a 20-foot-radius Sphere centered on that point makes a constitution saving throw, taking 7d8 Fire damage and blinds creatures till the start of their next turn on a failed save or half as much damage on a successful one. and depending on Gms discretion you steal one feature of a target over killed (2x the max hp or more) by the damage dealt it goes away on a short rest or when you gain a new feature in this way

Flammable objects in the area that aren’t being worn or carried start burning.

Using a Higher-Level Spell Slot. The damage increases by 1d8 for each spell slot level above 3.
