Warforged Juggernaut

Construct Perfection. While the juggernaut has more than half of its maximum hit points, it takes no additional damage from critical hits.

Juggernaut. Whilst grappling another creature, the juggernaut may move a Large or smaller creature without halving its speed.

Multiattack. The juggernaut makes two battle-axe attacks. If it has an armblade drawn, it can also make an armblade attack.

Battle-axe. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8+ 4) slashing damage, or 9 (1d10 + 4) slashing damage if used with two hands.

Armblade. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) piercing damage.

Demolishing Charge. The juggernaut moves 30ft in a straight line. The first time the juggernaut would enter another creature's space during its charge, the juggernaut may attempt to grapple that creature. If this movement would cause the juggernaut or a creature grappled by the juggernaut to enter a space containing an obstacle, the obstacle is destroyed (or partially destroyed if its size is large or greater), and the creature takes 6d6 bludgeoning damage. A creature takes this damage only once per charge, and once the movement has ended, the creature is no longer grappled.

Any time the juggernaut would enter a creature's space during this charge, that creature is moved to an adjacent empty space not in the juggernaut's path and must succeed on a DC14 Strength saving throw or be knocked prone.
