Regeneration. The troll regains 10 hit points at the start of its turn while immersed in water. If the troll takes 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.
Multiattack. The troll makes two attacks with its claws.
Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage.
This relative of the normal troll closely resembles its stronger cousin except that it has a very cold, semi-transparent body. These creatures dwell in moist areas of dungeons, usually near running water and have the same regenerative powers of a normal troll while immersed in water. They will always move towards a source of water if injured or threatened.
