Actions

Multiattack. The Broken makes six fist attacks.

Fist. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) 1d6+4 bludgeoning damage.

Withering Bolt. Cursed Spell Attack: +8 to hit, range 100 ft., one target. Hit: 35 (12d4 + 5) 12d4+5 Necrotic damage. Casting this reduces Broken's life energy by 25.

Web of Madness. The Broken One makes a telepathic connection with all creatures within 120ft with an intelligence of 8 or higher. Each creature linked must pass a DC 18 INT Save. Those who fail take 50 (10d8 + 5) 10d8+5 psychic damage as the Broken's memories of relentless dying spread to all creatures. If a creature succeeds it takes half the damage.

Wilting Tendrils. Tendrils from the void form a sphere with a radius of 10ft around The Broken One. Creatures inside are wrapped by the tendrils and must pass a DC 15 Cha save or be banished to the void. While in the void, the creatures are immobilized and enter a state of suspended animation. When Broken uses another ability besides its Fist attack, all creatures are brought back. They immediately take xd12+30 untyped damage, where x represents the number of turns the creature spent banished, with a minimum of 1d12.

Wrath of الشر القديم. A rift opens to the Void beyond at a point 120ft from The Broken One. Broken summons a destructive blast from this rift, which travels in a 200ft long 15ft wide line. All creatures in this line must pass a DC 18 CON save or take 167 (25d12 + 5) 25d12+5 untyped damage as the Void's energy drain their life away and be unable to move until the start of Broken's next turn. Creatures who pass take half damage with no extra effect.

Reactions

Soul Feast. Whenever a creature dies that Broken can see, Broken can use a reaction to absorb its soul. Doing so brings Broken's health up by:

25hp: Tiny/Small Creatures
50hp: Medium Creatures
75hp: Large Creatures
100hp: Huge Creatures
Maxhp: Gargantuan+ Creatures

Wicked Blast. As a reaction to being destroyed, The Broken One is consumed in a strange arcane explosion. All creatures within 120ft of it must pass a DC20 Con save. Creatures that fail the save take 55 (10d10) 10d10 necrotic damaged and are cursed. When a cursed creature casts a spell, they take 10 x the spell's level untyped damage. Only a greater restoration or wish spell can dispel the curse.

Wounding Swap. When a creature receives healing, The Broken One can use its reaction to curse the healing. The creature takes damage instead of being healed by the same amount. Broken is then able to heal for the amount of damage dealt x 10.
