Devil's Sight. Magical darkness doesn't impede the paeliryon's darkvision.
Keen Eyes. The paeliryon scores a critical hit on a roll of 19 or 20.
Magic Resistance. The paeliryon has advantage on saving throws against spells and other magical effects.
Spellcasting. The paeliryon casts one of the following spells, requiring no material components and using Intelligence as the spellcasting ability (spell save DC 17):
At will: Bestow Curse, Command, Darkness, Hold Monster, Major Image
1/day each: Antilife Shell, Incendiary Cloud, Scrying, Weird
Multiattack. The paeliryon makes three Claw attacks. It can replace one of the attacks with Draining Grasp (if available).
Claw. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit:16 (2d10 + 5) slashing damage plus 10 (3d6) fire damage.
Draining Grasp (Recharge 4–6). The paeliryon makes a Claw attack. On a hit, the target's Charisma score is reduced by 2 (1d4). This reduction lasts until the target finishes a short or long rest. A creature whose Charisma is reduced to 3 or less because of this ability, has the stunned condition for 1 minute.
One of the stronger greater devils, the paeliryon focus on corruption and obtaining mortal souls. While they can be found on almost every layer of the Nine Hells, paeliryons are particularly prominent in Dis and Malbolge, where they hold positions of power. Their duties include managing lesser devils, directing and manipulating the soul trade, and infernal politics. They're particularly talented at blackmailing and spying—abilities used both within and without the Nine Hells.
