Al'umet the Amalgam of Pain

Insanity (Mythic): This amalgamation of flesh, bone, and plants causes anyone who gazes upon its horrid form for an extended period of time to lose control of their attacks for a short period of time. 

• All players must succeed on a DC 13 Wisdom saving throw or become Frightened until the end of the next turn.

Enthralled (Mythic, Only when Unity occurs): The amalgamation of flesh, bone, and plant matter has finally found peace within its chaotic form and is no longer in pain. He has become a sight so beautiful you lose all will to fight it for a short while.

• All players must succeed on a DC 14 Wisdom saving throw or become Charmed until the end of the next turn.

Abominations Desperation: Able to use any of its three parts to attack you out of the pain of just its own existence: Barbs of Skeleton, Strike of Bloodied Meat, Whip of Deadly Flora.

Strike of Bloodied Meat: Melee Weapon Attack: +7 to hit, reach 12 ft., one target. Hit: 14 (2d10 + 3) [Bludgeoning] damage. The target must make a DC 12 Constitution saving throw or take 1d8 of [Acid] damage.

Barbs of Skeleton: Ranged Weapon Attack: +10 to hit, range 100 ft., one target. Hit: 20 (3d8 + 5) [Piercing] damage. The target must make a DC 14 Constitution saving throw or take 1d10 of [Necrotic] damage.

Fluid Movement (Costs 1 Actions). Able to contort its body to move 50 ft in any direction while blending in with the nature around it.

Wailing of the Tortured (Costs 2 Actions). Al'umet lets out a scream that causes confusion to anyone within a 60 ft radius. The targeted must succeed a DC 11 Wisdom saving throw or become Incapacitated until the end of the next turn.

"Become One With Me" (Costs 3 Actions). Al'umet sends out tendrils made of bone, flesh, and flora to ingest something from the nearby environment to heal itself and stop the excruciating pain of existence. Al'umet regains 25 hit points and deals an additional 2d4 of [Bludgeoning] damage.

Unity (Mythic Action, 1/Encounter): Once Al'umet reaches 50% HP, he begins to become more complete. The different parts of his body begin to connect together instead of wriggling around sporadically. Like his body finally decided to stop fighting itself. It has finally achieved the unity it so desperately desired at the expense of everyone around it. Make a DC 16 Wisdom saving through or be charmed for two turns and take 2d10 of Radiant damage. All status conditions are cancelled.
