Corrupt the Unhumble. At the start of the Vitiated Hybrid's turn, all creatures within 100 feet of it must make a DC 11 Wisdom Saving Throw or become stunned until the start of their turn. A creature at full hit points automatically fails this save.
Devour the Brave. Whenever a creature other than the Vitiated Hybrid takes damage, it gains a stack of frenzy. After gaining 3 stacks of frenzy, the monster immediately makes a Claw attack, and permanently loses 1 AC.
Thick Skin. The Vitiated Hybrid has resistance to physical damage from attacks. Upon being hit with a critical strike, or taking damage from a siege weapon, the monster loses this ability until the start of its next turn.
Multiattack. The Vitiated Hybrid makes one Claw attack and one attack with its Stymie Appendage.
Claw. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 20 (3d8 + 6) slashing damage.
Stymie Appendage. Melee Weapon Attack: +7 to hit, reach 60 ft., one target. Hit: 7 (1d8 + 2) bludgeoning damage. The target must make a DC 17 Strength Saving Throw or become restrained and be pulled 5 feet in a direction of the monster's choice at the end of every turn. Any creature within 5 feet of a lashed target can use their action to repeat the saving throw, ending the restrain on a success.
Vortex of Misery (Recharge 5–6). The Vitiated Hybrid makes a Stymie Appendage attack on all creatures within range.
