--Special Abilities--
Magic Immunity:
  A Valut Golem is immune to any spell that allows Spell Resistance, except as noted:
  - A lightning bolt spell removes effects of overheating and causes a Vault Golem to gain Haste for 2 rounds. 
  - Any effect that causes the Vault Golem to heat gives it the Overheat condition described below. 
  - Spells that cause metal to rust affect a Vault Golem normally
  
Overheat:
  If exposed to extreme temperatures such as a furnace or a Heat Metal spell, a Vault Golem will begin to overheat, slowing its movement. 
  - -6 penalty to dex 
  - movement penalty
  - Lasts 2 rounds after heat is removed

Cargo:
  If a Vault Golem is destroyed by massive damage, fire, or explosion there is a 75% chance that its contents are destroyed. 
  If the Vault Golem is immobilized or otherwise disabled, you can attempt to pick the lock. DC is 36 to pick the lock.
