Proboscis. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 10 (2d6 + 3) piercing damage, and the tick attaches to the target. While attached, the tick can't make Proboscis attacks. The tick can detach itself by spending 5 feet of its movement. As an action, a creature within reach of the tick can try to detach the tick, doing so with a successful DC 13 Strength check.

Blood Drain. The tick deals 10 (2d6 + 3) necrotic damage to one creature it is physically attached to, provided that creature isn't a Construct or an Undead, or 17 (4d6 + 3) necrotic damage if the creature is a Giant. The tick regains hit points equal to the damage dealt.
