Example using a 1st-level half-orc fighter who has failed a Will save as the character, are provided here.

A half-golem looks like a bizarre and horrifying melding of a golem and the character it once was. The materials of its golem limbs twine and crawl across its flesh, like ivy growing across a building or tree. In many cases, a half-golem's flesh is horribly scarred and has the pale gray color of death. Half-golems speak whatever languages they spoke before their transformations, but their voices are harsh and strangled.

A flesh half-golem is a tortured soul whose replacement limbs were stolen from the dead. Flesh golems' replacement limbs are rudely stitched to their bodies and may have different skin color or texture from the rest of the character's skin.

Berserk (Ex): A flesh half-golem that takes damage in combat flies into a berserk rage the following round, attacking wildly until either it or its opponent is dead. It gains +4 Strength, +4 Constitution, and -2 AC. A flesh half-golem cannot end its berserk state voluntarily. If the flesh half-golem is a barbarian, the bonuses and the penalty are cumulative with the barbarian rage class feature.
