Fassbender

Fassbender is a stone golem that Vox Machina was asked to retrieve from Westruun, which was under Umbrasyl's control at the time. As an NPC, Fassbender is played by Matthew Mercer.

The name "Fassbender" was given to it by Keyleth. Vex suggested naming him Spike.

Appearance
Fassbender is a twelve-foot-tall humanoid golem built of solid stone. The arms are giant and piston-like and the legs are like tree trunks. Vax'ildan drew a mustache and pointy goatee onto its face, which Keyleth later made permanent with her Stone Shape spell.
