Boron - I was thinking someone would put jade armor or boots of quickness on a golem. So +3 attack right? But I agree, the 8 base attack & defense is rather problematic.
Poor Arcoscephale indeed needs one booster to get a Golem. I think only R'lyeh can get Astral 3/Earth 2 without any boosts, as their Starspawns appear to have full randoms. Of course, only one Starspawn in 64 will qualify, but still.
