Magic Resistance

The clockwork leech has advantage on saving throws against spells and other magical effects.

Actions

Bite

+4 to hit, reach 5 ft (1.5 m). Hit: 1d6+2 piercing damage.

Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 5 (1d6 + 2) piercing damage, and the clockwork leech attaches to the target. While attached, the leech doesn't attack. Instead, at the start of each of the clockwork leech's turns, the target loses 5 (1d6 + 2) hp due to blood loss, and the target must succeed on a DC 13 Constitution saving throw or be poisoned until the start of the leech's next turn. The clockwork leech can detach itself by spending 5 feet of its movement. It does so after it drains 10 hp of blood from its target or the target dies. A creature, including the target, can use its action to detach the leech by succeeding on a DC 10 Strength check.

Tail

+4 to hit, reach 10 ft (3 m). Hit: 1d10+2 bludgeoning damage.

Melee Weapon Attack: +4 to hit, reach 10 ft., one target. Hit: 7 (1d10 + 2) bludgeoning damage.
