Actions

Multiattack. Harkin can attack up to 3 times.

Siphon. If Harkin has a creature grabbed, then he can choose to syphon their blood. The creature must roll a DC 18 Constitution saving throw. If failed, then the creature takes 2d8 necrotic damage, and Hardin heals for 2d10. If the creature succeeded then they will take half damage, and Harkin won’t heal.

If the creature has been hit with Hemorrhage, then it automatically fails, and receives 2d10 damage, and Harkin heals for 3d10 instead.

Bloody Tendril. If a large enough quantity of blood is present, then Harkin can form a single 10ft long tendrils within 120ftt of himself, with the number of maximum tendrils he can control being based on the number of opponents he is currently facings (one for each creature). These tendrils are immobile, with 10 HP and 14 AC. On Harkins initiative, these tendrils can use 1 action to either grab or attack anything within their reach, with the save DC being 16, and the damage being 2d6 Necrotic damage. Their attack modifier is based on Harkins current Melee Weapon attack bonus, and the DC being 16.

Warp Blood. Harkin can use the surrounding Blood to make any 10ft cubic structure. If Harkin has access to his Blood Rain, then this goes to a 20ft cube; 30ft cube if he has access to a large body of water (refer to Regional Effects)

Bloodletter (Hilt form). Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 7 (2d4) Stabbing damage. As a reaction, Harkin can make a DC 18 Constitution saving throw. On a fail, blood is extracted from the creature to form the hilts blade, dealing an extra 2d10 damage.

Bloodletter (Sword form). Melee Weapon Attack: +9 to hit, reach 5 ft., one creature. Hit: 11 (2d8+5) Slashing damage, or 20 (2d10+5) if two-handed.   Additionally, the sword blade can be broken off in a creature on a successful attack. On command, the creature must make a DC 15 Constitution saving throw as the blade bursts into pieces inside them, dealing 4d6 on a failure or half as much on a success.
If the blade is used on the same creature that helped create the blade, then they roll with disadvantage, and takes an additional 1d6 of damage

Regional Effects

Harkins lair is only bound by whether or not he has access to the open sky. When he finds himself outside, the following effects can be noticed:

• Blood rains from the sky, coating the ground, exposed objects & creatures.
• Bodies of water such as rivers, streams or lakes turn to blood. If a creature finds themselves in this blood, their movement is halved.
• The sky turns a deep crimson red, and similarly colored clouds blot out the sun.
