Stone Golem

Stone Golems are Pit-sized statues armed with halberds. They normally stand fast but will set their weapons and move forward if Pit lands on the same level as one. They have no other attack than to attempt to spear Pit, but it can be hard to move past them in close quarters. They only appear in Fortresses.

"Normally quite still, but starts moving if it sees Pit."

Trivia

 * The Stone Golem is based on the creature of the same name. Golems originated from Jewish mythology and are said to be humanoid monsters made entirely out of nonliving material.
