Bastion

Brute. Bastion's melee weapon attacks deal one extra die of its damage type on a hit (included in the attack).

Shelter. Allies within 5 feet of the Bastion gain a +2 bonus to their AC, if the Bastion is not prone or incapacitated.

Shield Charge. If the Bastion moves at least 10 feet straight toward a target and then hits them with its flail on the same turn, the target takes an extra 14 (3d8) bludgeoning damage. If the target is a creature, it must succeed on a DC 17 Strength saving throw or be knocked prone.

Multiattack. The Bastion makes two weapon attacks.

Flail. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage.

Javelin. Melee or Ranged Weapon Attack: +9 to hit, reach 5 ft. or range 30/120 ft., one target. Hit: 11 (2d6 + 4) piercing damage.

Block. The Bastion adds a +3 bonus to AC against an attack that would normally hit it. To do so, the Bastion must see the attacker and be wielding a shield.
