Cult of Mephistopheles
Diabolical Cult
Cult Lore & Traits

Mephistopheles's cultists can gain the Spell Shield trait. Cult leaders can also gain the Spell Leech trait.

This creature gains advantage on saving throws against spells. If it succeeds on such a saving throw, it gains temporary hit points equal to the spell's level.
