Medium monstrosity, unaligned

Actions

Multiattack. The lagavulin makes two slash attacks.

Slash. Melee Weapon Attack: + 5 to hit, reach 5 ft., one target. Hit: 12 (3d6 + 2) slashing damage

Metallicize. The lagavulin hardens its shell, reducing bludgeoning, piercing, and slashing damage it takes from nonmagical weapons by 3. This effect ends if the lagavulin is not targeted for one round.

Siphon Soul. The lagavulin forces a creature it can see within 10 feet of it to make a DC 15 Constitution saving throw. On a failed save, the target's Strength and Dexterity scores are each reduced by 1 until it finishes a long rest. The target dies if this reduces its Strength or Dexterity to 0.
