Cognitive Giant

Anguish Engine. The pain and anguish emitted from others fuels the Cognitive Giant's capabilities, allowing it to gain xd4 + x temporary hit points, where x is the number of  opponents it hits with a melee attack. These temporary hit points are reduced to 0 on the beginning of the Cognitive Giant's next turn.

Swift Fists. The Cognitive Giant, being built to ward off intruders, are swift and proficient with their large fists. The Cognitive Giant is proficient with melee attacks, and may use a bonus action to make an additional melee attack, if it has already done so during its turn. (Multi-attack does not count as a melee attack for this condition)

Multi-attack. The Cognitive Giant makes 3 Clockwork Strike attacks or 2 Spring-Locked Lunge attacks.

Clockwork Strike. Melee Weapon Attack: +2 to hit, reach 10 ft., x targets (See Below). Hit: 20 (3d8 + 5) bludgeoning damage. For each Clockwork Strike attack made during a single turn, the Cognitive Giant may target an additional creature including the previous target.

Spring-Locked Lunge. Melee Weapon Attack: +3 to hit, reach 30 ft., 1 target. Hit: 25 (6d6 + 4) bludgeoning damage. Creatures within a 15 ft. radius must succeed a DC 15 Dexterity saving throw and take 3d6 + 2 force damage on a fail, or half on a success.

Power Blocking. The Cognitive Giant can use its large limbs to absorb large attacks, and converts its own pain into energy. The Cognitive Giant may use a reaction to block an attack or spell targeted towards it by rolling DC 15 Constitution Save. On a success, the Cognitive Giant takes half the intended damage, and receives x temporary hit points, where x is the total amount of damage of the attack. On a fail, the Cognitive Giant is incapacitated until the end of its next turn.
