Traits

Overheat: Every turn that Cold-Blooded isn't active, the Blood Boiler can use two attacks per action.

Cold-Blooded (Stackable): After being hit by an attack that inflicts Cold damage, this monster can only use one attack per action and its movement speed is reduced to 0 until its next turn.

Siphon: Once per turn, the Blood Boiler can heal for 2d8+6 after doing Slashing or Piercing damage.

Blood Bond: After a successful hit with Decrepit Drain, the Blood Boiler and creature it has attack become bonded. Whilst bonded, any damage taken from the other party is taken to itself and vice versa at 1/2 damage (rounded down). A creature must use a bonus action to make a DC 16 Constitution saving throw; on a natural 20, the Blood Boiler becomes Cold-Blooded for one turn.

Actions

Greatblade of Blood: Melee attack: +4 to hit, reach 10ft, 1-3 targets, Hit: 2d12+6 Slashing damage 

Decrepit Drain: Melee attack (costs 2 attacks): +4 to hit, reach 5ft, 1 target, Hit: 10d6+6 Piercing damage + inflicts target with Blood Bond effect.

Blood Bolt:  Ranged attack: +4 to hit, reach 60ft, 1 target, Hit: 2d6+6 Piercing + 1d6 Fire.

Description

These strange creatures seem to have no recognizable features besides the fact that they are made entirely of sentient blood. The blood they are made from tends to bubble from time to time and they emit a strange heat. They vaguely resemble the anatomy of a humanoid with the proportions of a human or elf. It is believed that these creatures were once cultists of a creature from the hells who had failed their patron and since been cursed. Many people avoid looking at its facial region as it tends to inflict a feeling of emptiness, guilt or sadness and sometimes resembles a face of a loved one.
