Your infernal allies can grant you a boon. As a Bonus Action, you can gain the benefits below for 1 minute or until you choose to end them (no action required). Once you use this feature, you can't use it again until you finish a Short or Long Rest.
Devil's Charm
You have Advantage on Charisma checks and saving throws.
Hellfire Aura
At the end of each of your turns, each creature you choose in a 10-foot Emanation originating from you takes 2d6 Fire damage.
Infernal Interruption
Whenever you use your ValdaSpire24, you can cast Hellish Rebuke without a spell slot as a part of the same Reaction, as if the creature damaged you with the interrupted attack. Charisma is your spellcasting ability for this spell.
