The Ten Hells

You utter a divine word, imbued with the power that shaped the world at the dawn of creation. Choose any number of creatures you can see within range. Each creature that can hear you must make a Charisma saving throw. On a failed save, a creature suffers an effect based on its current hit points:

• 50 hit points or fewer: blinded until uncursed 
• 40 hit points or fewer: [Tooltip Not Found] affected will lose movement from tibia rupturing outward from the flesh
• 30 hit points or fewer: [Tooltip Not Found], affected will have flesh turned inside out, [Tooltip Not Found] affected will lose movement from tibia rupturing outward from the flesh
• 20 hit points or fewer: killed instantly

Regardless of its current hit points, a celestial, an elemental, a fey, or a fiend that fails its save is forced into the abhorrent void eternally to be consumed by the inescapable madness and can't return to your current plane for by any means short of a wish spell.
