Curse of Ilana Sorowid

Bound Existence. The curse is spiritually tethered to its vessel. It has a base HP of its patron, which is added to its vessel's HP pool when manifested in combat. Any damage it takes is deducted from this shared pool. If her vessel falls to 0 HP, the curse immediately vanishes.

Hexblade’s Guardian. The curse can only fully manifest in combat when her vessel makes an attack or takes damage. It remains until combat ends or the vessel is incapacitated. When combat ends, the curse can return to its uncursed form.

Hexed Echo. When its vessel casts Hex for the first time in combat, the curse can duplicate the effect, placing a second Hex on another creature or on the same creature within range as a reaction. 

Eldritch Echo. Whenever its vessel casts Eldritch Blast, the curse can also cast Eldritch Blast on the same creature within range as a reaction. 

Mage Armor (At Will). The curse can cast Mage Armor at will (without expanding a spell slot) on itself or its vessel.

False Life (At Will). The curse can cast False Life at will (without expanding a spell slot) on itself or its vessel.

Hexblade Patron. Whenever the curse hits an attack, it can choose deal Necrotic, Psychic, or Radiant damage or its normal damage type.

Multiattack. The curse can make two attacks, choosing from Bite, Claws, Heavy Slam, or Eldritch Blast.

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: (1d10 + 4) piercing damage, and Ilana heals for half the damage dealt.

Claws. Melee Weapon Attack:+6 to hit, reach 5 ft., one target.
Hit: (1d8 + 4) slashing damage. If both Claw attacks hit the same creature in a turn, the target is grappled (DC 14).

Heavy Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one target.
Hit: (1d12 + 4) bludgeoning damage.

Eldritch Blast. Ranged Spell Attack: +6 to hit, range 120 ft., one or two targets.
Hit: (1d10 + 2) force damage.

Misty Step (2/Short Rest)

The curse magically teleports up to 30 feet to an unoccupied space it can see.

Expeditious Movement (At Will)

The curse takes the Dash action and can use it as a bonus action as well.

Guardian’s Curse (Reaction). When its patron is targeted by an attack, the curse imposes disadvantage on the attack roll by momentarily phasing between its patron and the attacker.
