Amani, King of All Trolls

Regeneration. The troll regains 10 hit points at the start of its turn. If the troll takes acid or fire damage, this trait doesn't function at the start of the troll's next turn. The troll dies only if it starts its turn with 0 hit points and doesn't regenerate.

Frenzied Stroke. When Vard's attack brings an enemy beneath half health, Vard can make a Claw attack.

Bound to the Cauldron. If the stone cauldron is destroyed, Amani takes 40 damage and howls in pain. If the stone cauldron is intact when Amani is reduced to 0 hit points or fewer, the troll king's body turns into a dark fog that flows back into the Cauldron. One round later he reformers with 174 hp and without Moran's Eye (see he cannot use baleful eye or smoldering eye powers). If the Cauldron is already destroyed when Amani is defeated, his essence dissipates.

Legendary Resistance (3/Day). If the dragon fails a saving throw, it can choose to succeed instead.

Multiattack. Amani takes two attacks with his claws.

Claw. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 19 (3d8 + 7) slashing damage.

Propelling Swipe. Melee Weapon attack: DC 17 DEX saving throw for all targets within 10 ft. Those that fail take 3d8+7 slashing damage, the target is pushed 10 ft away from Amani, and knocked prone. If Amani takes acid or fire damage, propelling swipe does not function until the end of his next turn.

Smoldering Eye. All targets in a 25 ft cone must succeed on a DC 19 Dexterity saving throw or take 2d10 + 7 fire damage and become burned (-2 penalty on attack rolls). The target can repeat the save at the end of their turn to end the effect. Amani takes 10 psychic damage when he uses this power.

Baleful Eye. A target within sight must succeed on a DC 19 WIS saving throw or the target is slowed and cannot teleport. The target can repeat the save at the end of its turn to end the effect. The effect also ends if Amani uses Baleful Eye on another target.

Nectroic Bond. When Amani takes damage, the enemy must make a DC 19 WIS saving throw or take 10 (3d6) ongoing necrotic damage. The target can repeat the save at the end of their turn to break the bond.

Amani 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. Amani regains spent legendary actions at the start of its turn.

Claw. Amani makes a claw attack.

Mummify. One creature which has a necrotic bond with Amani, must succeed on a DC 19 Dexterity saving throw or become mummified (restrained) in mummy wraps.

Shrink. The target must succeed on a DC 19 Wisdom saving throw or take 10 (3d6 psychic) damage and have their Strength and Constitution reduced by 1. (Costs 2 Actions)
