The rook is a potent golem, a fusion of stone and clay golem designed like a keep or watchtower on its back. It has murder holes and crenelations at the top, allowing it to release waves of burning oil on all enemies that would fight it in melee or even have soldiers holed up inside its garrison, firing arrows and even spells at enemies at range. One of its arms is outfitted with a massive siege flail while the other arm is a hand that can catapult stones at its enemy from a distance.
