, and the tick attaches itself to the target. The target has the Grappled condition (escape DC 14). While attached, the tick can’t make Bite attacks, and the target takes 7 (2d6) Necrotic damage and must succeed on a DC 11 Constitution saving throw or gain 1 Exhaustion level (a creature can gain a maximum of 1 Exhaustion level from the ability). The tick can detach itself by spending 5 feet of its movement.

Immediately after dealing Necrotic damage with its blood drain, the tick regains Hit Points equal to the damage dealt.
