Cursed Centi Centaur

Tackle and Pummel. If the centaur moves at least 30 feet straight toward a target, it has advantage on checks for a grapple. If grappled successfully, centaur can drop its weapons and make a pommel attack with four of its fists. Centi Centaur suffers one level of exhaustion. 

Cursed Chain. If the centaur drops its weapons for the tackle and pummel condition, or for any other reason, centaur can pull its magical weapon out, Chain of the Cyzan Knight. 

Brute Endurance. The last damage type the centaur will deal out, it will be resistant to until the beginning of its next turn.

Attuned with the Earth. Any creature within 120ft of the Centi Centaur makes stealth checks at disadvantage. Centi Centaur can sense underground movement up to 50ft below ground. In darkness, or magical darkness, Centi Centaur has tremorsense. 

Multiattack. The Centi Centaur can make up to 5 attacks in a turn. 2 with its hand axes, 1 with its long bow, 2 with its fists.

Handaxe. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 9 (1d6 + 7) slashing damage.

Direction. As a bonus action, the Centi Centaur may call upon one of its Centaur's strength, giving it advantage on its next roll.

Grapple Slam. As a bonus action, the Centi Centaur can, if currently grappling a creature, slam its two upper fists into the body of the creature, making a Fists attack that is automatically a critical hit, if landed. 

Elder Sense. If any of its brother centaurs have been injured, the centaur may attack the targeting creature with its longbow or Chain attack.
