Agosuos

Charge- If the Agosuos moves at least 10 feet straight toward a target and then hits it with a gore attack on the same turn, the target takes an extra 18 (4d8) piercing damage. It must succeed on a DC 16 Strength saving throw or be pushed up to 10 feet away and knocked prone.

War God's Blessing (1/rest)- Being a child of the war god Ha Teh Khaan, the Agosuos can use the fighting power inside him to gain advantage in battle. The Agosuos can use its action to force every creature within 60 feet of it to make a DC 14 Wisdom saving throw, or be frightened.

Weak Point- If the Agosuos is hit by a critical hit that does piercing damage, roll 2 extra dice, instead of one.

Beresk- Whenever the Agosuos starts its turn with 40 hit points or fewer, roll a d6. On a  6, the Agosuos goes berserk. On each of its turns while berserk, the Agosuos attacks the nearest creature it can see. If no creature is near enough to move to and attack, the golem attacks an object, with preference for an object smaller than itself. Once the Agosuos goes berserk, it continues to do so until it is destroyed or regains all its hit points.

Feet of the Goat- The Agosuos' jump distance is doubled.

Fearsome- The Agosuos has advantage on checks and saving throws against being frightened.

Multiattack. The Agosuos makes 3 attacks, 2 with its greataxe, and 1 with its kick. It can use its War God's Blessing or Gore in place of all the attacks.
