Potions of oil are potions that can be used in a few different ways:

  • If drunk, the PC will become poisoned
  • Blessed potions can coat items dipped into them, making metal items rustproof and others waterproof. However, they do not remove rust, so it is possible to create rusty rustproof weapon. Waterproof can be applied to scrolls and books, but these are normally protected by waterproof blankets.
  • Potions of oil can be 'u'sed while standing on an alarm trap to silence it, removing the trap. Since alarm traps are not dangerous and character needs to stand on the trap to silence it anyway, this application is mostly useless.


Rustproofing certain (ego) weapons made from iron can be rather valuable.
