Loathsome, Regenerating Lurker

Habitat: Arctic, Forest, Hill, Mountain, Swamp, Underdark; Treasure: None

Trolls creep forth to prey on smaller creatures and drag captives back to festering lairs. These misshapen brutes can regenerate from wounds and regrow severed body parts—including their heads. A troll’s severed limbs continue to move and attack. Unless they’re burned by flames or acid, trolls can recover from egregious wounds and seek revenge on those who felled them.

Trolls typically hunt alone, but small groups occasionally cooperate to ambush prey or raid villages. Creatures such as hags and hill giants might convince trolls to work for them in exchange for disgusting meals.

Traits

Loathsome Limbs (4/Day). If the troll ends any turn Bloodied and took 15+ Slashing damage during that turn, one of the troll’s limbs is severed, falls into the troll’s space, and becomes a Troll Limb. The limb acts immediately after the troll’s turn. The troll has 1 Exhaustion level for each missing limb, and it grows replacement limbs the next time it regains Hit Points.

Regeneration. The troll regains 15 Hit Points at the start of each of its turns. If the troll takes Acid or Fire damage, this trait doesn’t function on the troll’s next turn. The troll dies only if it starts its turn with 0 Hit Points and doesn’t regenerate.

Actions

Multiattack. The troll makes three Rend attacks.

Rend. Melee Attack Roll: +7, reach 10 ft. Hit: 11 (2d6 + 4) Slashing damage.

Bonus Actions

Charge. The troll moves up to half its Speed straight toward an enemy it can see.
