Cleansing Flame

Cantrip used by Preserver Wizards in Athas. It's just like the cleric cantrip, Sacred Flame, but can only target defilers, templars who serve defilers, and undead.

A flame-like radiance descends on a creature that you can see within range. The target must succeed on a Dexterity saving throw or take 1d8 radiant damage. The target gains no benefit from cover for this saving throw.

The spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
