Vampiric Ooze

Amorphous. The jelly can move through a space as narrow as 1 inch wide without squeezing.

Spider Climb. The jelly can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Pseudopod. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage plus 3 (1d6) acid damage.

Latch And Leech. The Vampiric Ooze latches onto a creature and sucks their blood. 2 Piercing Damage and then 1.5 Damage for every action the Vampiric Ooze makes while attached to the creature. A Creature can attempt to remove the ooze as an action by rolling a strength ability score. If the roll is 12 or more the Ooze is successfully removed. The Creature that the Ooze was removed from will take 0.5 damage until their wound is cauterized or covered up enough.

Split. When a Vampiric Ooze that is Medium or larger is subjected to lightning or slashing damage, it splits into two new Oozes if it has at least 10 hit points. Each new Ooze has hit points equal to half the original Oozes, rounded down. New Oozes are one size smaller than the original Ooze.
