Assimilate Lava An obsidian golem that submerges itself in lava or magma takes no damage from it, and for as long as it remains submerged, it becomes slowed 2 and gains fast healing 15.

Golem Antimagic harmed by sonic (8d10, 2d10 from area or persistent damage); healed by cold (area 2d10 HP); slowed by fire.

Vulnerable to Shatter Casting a shatter spell on an obsidian golem affects the golem normally, but also causes jagged chunks of obsidian to flake off its body. The squares on which the golem was standing (or the squares below it, if it was flying) become difficult terrain.

Fling Shards [>] The obsidian golem slings razor-sharp shards of itself in a 15-foot cone. Creatures in the area take 4d8+9 slashing damage (DC 37 basic Reflex save).

Shred Armor An obsidian golem's body is so sharp that it tears through armor like a knife through butter. Whenever the golem scores a critical hit with a fist Strike against a creature wearing non-adamantine armor, the creature's armor becomes broken.
