The Bone Golem is the second mini-boss of Relic Maze. It resembles a skeleton of a four-eyed emu with a ruby as it's source of power. It is fought in what looks like a small, old and abandoned library in the shrine.

Its attack pattern will consist of walking around the room and pecking the ground. Whenever it pecks the ground, damaging shock waves will come out, making the attack somewhat hard to dodge. Standing on the Bone Golem's back will cause it to peck itself for major damage. If playing as Lilac, dodging the attack while the Golem hits itself will cause her to say: "Hit me if you can!" Making the Bone Golem destroy itself will earn the player the All Bone, No Brains Achievement.
