This golem is summoned when someone opens a trapped chest in the Tomb of Horrors. It has identical stats to the Clay Golem, but with worse natural attacks (it wields scimitars, dealing less damage than the Clay Golem's slams. It cannot make iterative attacks with them. A nice DM may allow it to put them down and choose actual weapons, but it's unclear if it's possible or if the scimitars are built stuck to its arms), worse DR by 5 points, and a worse haste ability, since the Bone Golem's requires a standard action to activate.
A Bone Golem's Magic Immunity isn't bypassed by any spell.
If the Clay Golem didn't make the cut, then this one isn't worth positive LA either. See you tomorrow.
