Blood Elemental Titan

Blood Siphon. The elemental siphons the blood out of a enemy creature that it hits, dealing Hit: 17 (3d10) necrotic damage. This does not affect any creature that does not have blood. It regains half the damage dealt. This damage can only be rolled twice a turn.

Freeze. If the elemental takes cold damage, it partially freezes; its speed is reduced by 5 feet until the end of its next turn.

Poisoned Blood. If the elemental takes poison damage, it deals half the damage to the next creature it hits.

Bloody Trail. When the elemental moves and is not moving through an area covered in blood, the elemental takes Hit: 7 (1d12) damage for every 30 feet moved including extra squares not covered. The area it moves through is now covered in blood for the next 10 minutes.

Multiattack. The elemental makes two claw and one stomp attack.

Claw. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 13 (2d6 + 5) bludgeoning damage.

Stomp. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 12 (1d12 + 5) bludgeoning damage. The creature must make a DC 17 STR saving throw or be knocked prone.

Blood Implosion (Recharge 6). Each creature within 30 ft of the elemental must make a DC 17 CON saving throw. A creature without blood automatically succeeds on this saving throw. Blood is ripped out of the creatures body and siphoned into the elemental, giving the elemental advantage on attacks until the end of its next turn also healing half the damage dealt. On a failure, a creature takes Hit: 20 (3d12) necrotic damage, half on a success.

Bloody Rebuke. The elemental takes Hit: 7 (2d6) necrotic damage that cannot be reduced in any way and deals double the damage taken to the target that triggers this reaction.

The elemental gains 1 legendary action a turn and can have a maximum of 3.

Claw (Cost 1 action). The elemental makes one Claw attack.

Blood Step (Cost 3 actions). The elemental teleports to an area covered in blood at least 25 ft by 25 ft in size within 100 ft and teleports to the center of it.
