An adamantine golem’s slam attacks threaten a critical hit on a 19 or 20. In addition, whenever an adamantine golem scores a critical hit, it deals 6d10+13 points of damage to the target’s armor or shield in addition to the normal damage, as if it had also made a successful sunder combat maneuver.
An adamantine golem is nearly impossible to destroy. Even if reduced below 0 hit points, its fast healing continues to restore hit points, though the golem is helpless unless above 0 hit points. It can only be permanently destroyed if reduced to negative hit points and then decapitated using an adamantine vorpal weapon—alternatively, miracle or wish can be used to slay it while it is at negative hit points.
An adamantine golem is immune to any spell or spell-like ability that allows spell resistance, except as noted below.
