Ward of the Pure Soul

You touch a willing creature, enveloping it in a radiant shield that provides extra resistance against Blighted attacks. For the duration, the target gains advantage on all saving throws against Blighted spells and effects, and whenever the target is hit by a Blighted creature, the attacker takes 2d6 radiant damage.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the radiant damage dealt increases by 1d6 for each slot level above 4th. You must sacrifice an additional 3 HP per slot level above 4th.
