Blood Pudding

Primal Strikes. The Blood Pudding ignores other creatures' resistance and immunity to nonmagical bludgeoning, piercing, and slashing damage.

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

Shapeless The Blood Pudding can fit into any crack or hole leaving behind all its items in their body that are too big for the hole.

Form Any Shape The Blood Pudding can take form to any shape from monstrous to humanoid to plain shapeless forms.

Dormancy The Blood Pudding may hibernate for any amount of time without food, but remains vigilant during this time. They do not naturally do this, preferring to endlessly seek prey by night.

Magic Resistance The Blood Pudding has advantage on saving throws against spells and other magical effects, it's also resistant to all magical damage.

Blood Infusion Drinking alcohol weakens an infused Blood Pudding and reduces the Constitution damage sustained from its disgorge attack by one-half for the next 1d4+1 rounds. Consuming pure vinegar causes an infused Blood Pudding to eject itself from the host in the same round the vinegar is consumed. A creature drinking pure vinegar must make a successful DC 18 CON save or be nauseated for 1d6 rounds. A Blood Pudding will not use its infuse attack against that host for one day.

Sunburns When the Blood Pudding is exposed to direct sunlight it suffers 1d4 damage every minute, emitting steam and this kind of damage causes the Blood Pudding to feel something like pain.

Multiple Attacks The Blood Pudding makes four attacks.

Pseudopod Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 5) bludgeoning damage plus 10 (3d8) Necrotic damage. In addition, nonmagical armor worn by the target is partly dissolved and takes a permanent and cumulative -1 penalty to the AC it offers. The armor is destroyed if the penalty reduces its AC to 10.

Bloody Glob Ranged Weapon Attack: +10 to hit, range 20/80 ft., one target. Hit: 21 (4d6 + 7) bludgeoning damage plus 7 (2d6) Necrotic damage. In addition, nonmagical armor worn by the target is partly dissolved and takes a permanent and cumulative -1 penalty to the AC it offers. The armor is destroyed if the penalty reduces its AC to 10.

Disgourge A Blood Pudding that has infused itself with a host can force the creature’s blood out through its pores, eyes, ears, and mouth. This is a standard action that deals 1d8 points of Constitution damage each round. At Constitution 0, the host dies and the Blood Pudding feeds on the corpse. When sated, the Blood Pudding exits, and to onlookers it appears as if the slain creature is bleeding profusely

Hemovore The Blood Pudding heals 1d10 for each ounce of blood drank from a victim or corpse for each round it is grappled or Disgorged to a person.
