Bloodsucker (5e Creature)
From D&D Wiki
Medium monstrosity, unaligned
Cold Blooded. The bloodsucker's thermoregulation is similar to that of a frog or a lizard. This makes it impossible to identify it via infravision.
Sunlight Sensitivity. While in sunlight, the bloodsucker has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.
Multiattack. The bloodsucker makes two attacks with its claws.
Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) slashing damage.
Blood Drain. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 5 (1d6 + 2) piercing damage, and the bloodsucker attaches to the target. At the start of each of the bloodsucker's turns, the target loses 5 (1d6 + 2) hit points due to blood loss.
Invisibility. The bloodsucker magically turns invisible until it attacks or until its concentration ends (as if concentrating on a spell). Any equipment the bloodsucker wears or carries is invisible with it.
A standard bloodsucker looks almost human, but has a hunched stance and grey or brown skin. Instead of a mouth it has several strong tentacles, which it uses to feed on other creatures. So far, there have been seen only three types of bloodsuckers: the underground bloodsucker, the marsh bloodsucker and the albino bloodsucker.
