Obsidian-Back Giant

A volcanic giant armored down its spine in plates of black glass that grind and spark as it moves. It is sullen and slow to rouse, but every wound that lands feeds its temper. Push it too far and it convulses, flinging a storm of razor shards across everyone close enough to have made it bleed.

Obsidian Fist: slashing/bludgeoning, melee/10 ft, +6 to hit, 3d8+5. Shard Shed: 15-ft radius, save Dex Quick or 3d6 slashing and bleeding 1, cooldown 3 rounds.

Glassback Armor: DR 4 from rear/flanks; thunder or pick-like weapons crack plates and lower DR. Senses: Night Vision (60 ft).
