For the next 10 minutes, the creature’s speed is doubled, it gains a +4 bonus to its Strength and Dexterity score, and it ignores the effects of exhaustion. When these effects end, the creature gains a level of exhaustion and must succeed on a DC 10 Charisma saving throw or be possessed by a devil for 1 hour. After you use this property, you can’t do so again until the following dawn when it refills with refined fiend’s blood.
