Obsidian golems are massive golems that frequently guard volcanoes. They are brittle compared to other golems, but can withstand heat far more easily.
These creatures resemble towering humanoids composed of obsidian. They are completely faceless, like most golems.
Obsidian golems have a far greater heat tolerance than most golems. Because of this, sorcerers often use them to guard extremely hot locations such as volcanoes. They are usually not the only guardians, as they are brittle and can be destroyed easily.
