Blood Elementals are typically created as a powerful mage knows their end is near. A common option for those who would seek the power of lichdom, but are not quite powerful enough to achieve it. Fiercely protective of the knowledge and power they've discovered, they create the elemental on their deathbed, to watch over their remains and most prized possessions.

Tethered. The elemental is poisoned while more than 120 feet from its anchor point. The demon can't willingly move more than 1 mile from its anchor point.

Actions

Multiattack. The elemental makes two blood lash attacks. It can then use Life Drain if it's available.

Blood Lash. Melee Weapon Attack: +6 to hit, reach 10ft., one target. Hit; 11 (2d6 + 4) slashing damage. If the target is affected by Life Drain, the elemental regains 2 hit points.

Pool Form. The elemental retreats into a pool of blood. In this form, it can't take actions but is immune to the damage from attacks. It can return to its normal form at any time on its turn. If the elemental becomes poisoned or incapacitated, it exits the pool immediately and cannot enter it.

Life Drain (Recharge 5-6). Each creature within 30 feet of the elemental must succeed on a DC 13 Constitution saving throw or take 5 (1d10) necrotic damage and become unable to regain hit points until the start of the elemental's next turn. The elemental regains hit points equal to the total necrotic damage dealt.

Reactions

Dissipate. The elemental adds 3 to its AC against one attack that would hit it.
