XaXa - Il Martello

Pillar Maul Bonk. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 137 (22d12+5) bludgeoning damage.

Self-Determination. XaXa buffs the damage of his subsequent <Pillar Maul Bonk> by 20%, also gaining an advantage during the action (max. 1 per enemie).

Opportunity Attack. XaXa can make an opportunity attack when a hostile creature that he can see moves out of your reach. To make the opportunity attack, XaXa uses his reaction to make one melee attack against the provoking creature. The attack occurs right before the creature leaves your reach.

Mega Bonk. Once per fight, WeWe raises his hammer with both hands activating a ritual ending with its slamming back on the ground, resulting in every enemie creature in a radius of 100 ft. to be affected by terror:
it's worse than being frightened, it makes creatures hunker down and hide behind their shield or run and provoke attacks. While afflicted by terror, you suffer the Frightened condition and must take either the Dodge or Dash action on your turn, but you can act normally otherwise. In addition to that every enemie receives a disadvantage on future attacks (escape DC 18 CHA).

Hammer Duplication. Choosing to lock <Self-Determination> and if it wasn't already used during this fight, XaXa evokes a second hammer (max. 1).

Double Maul Attack. Unlocked Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 269 (44d12+5) bludgeoning damage.
