Gordon's Tunic

Decreases damage taken from fire, electricity, poison, and explosions by 50%. This includes direct attacks (for example, Imps' attacks) and indirect damage (e.g, being set on fire).

Trivia
This relic's flavour text is a reference to Gordon Freeman from the Half Life series, but the relic was originally intended to be a reference to the Goron's Tunic from The Legend of Zelda series.
