Ulamog's innate spellcasting ability is Wisdom (spell save DC 22). It can innately cast the following spells, requiring no material components: • At will: detect magic, dispel magic • 3/day each: confusion, counterspell (9th level spell slot), weird • 1/day each: divine word, feeblemind, plane shift
IfUlamog fails a saving throw, it can choose to succeed instead.
Ulamog has advantage on saving throws against spells and other magical effects.
Ulamog's weapon attacks are magical.
When Ulamog reduces a creature to 0 hit points, that creature's body becomes a pile of white dust.
Ulamog can use its Maddening Presence. It then makes six attacks: four with its fists, and two with its tentacles.
Melee Weapon Attack: +19 to hit, reach 20 ft., one target. Hit: 36 (4d12+10) bludgeoning damage.
Melee Weapon Attack: +19 to hit, reach 30 ft., one target. Hit: 28 (4d8+10) bludgeoning damage. If the target is a creature, it must succeed on a DC 20 Strength saving throw or be knocked prone.
Each creature of Ulamog's choice within 120 feet of it and aware ofit must succeed on a DC 18 Wisdom saving throw or become afflicted with short-term madness (Dungeon Master's Guide pg. 259). If a creature afflicted with short-term madness fails its saving throw, it becomes afflicted with long-term madness. If a creature afflicted with long-term madness fails its saving throw, it becomes afflicted with indefinite madness. If a creature afflicted with indefinite madness fails its saving throw, it dies from psychological trauma. If a creature's saving throw is successful, the creature is immune to Ulamog's Maddening Presence for the next 24 hours.
Ulamog can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Ulamog regains spent legendary actions at the start of its turn.
Ulamog makes a fist attack. If the attack hits, the target is grappled (escape DC 20) if it is a Huge or smaller creature and Ulamog doesn't have four other creatures grappled. Until this grapple ends, the target is restrained and takes 4d10 psychic damage at the start of each of its turns.
Ulamog casts phantasmal killer, no concentration required.
Ulamog casts banishment.
