The Golem is an enemy in Heretic. They are hulking tan humanoids that attack up close with their fists. Nitrogolems are more powerful Golems that have an attack where they charge up an aura of flames, and then launch a screaming fire skull that homes in on their victim. Both the regular Golem and the Nitrogolem come in ghost versions as well.
When Golems are killed, they split in half and collapse into a surprisingly small pile of bloody flesh with no skeleton, releasing an evil spirit which is visible for a fraction of a second before disappearing harmlessly. Sometimes they drop a Wand Crystal, but these are only worth 3 shots instead of the usual 10. While not as strong as the Sabreclaw, the Golem's melee attack seems to be more powerful then the Sabreclaw's one.
