Immunity

Immunity refers to a creature's resistance to some type of damage or ability.

Some creatures are known to be immune to:
 * Poison
 * Fire
 * Energy
 * Physical Damage
 * Drunkenness
 * Invisibility
 * Life Drain
 * Paralysis

This means that, for example, if a creature is immune to Fire, it will not be damaged by any attacks from a Volcanic Rod, Great Fireball rune, or any other attack that causes fire damage.

Players can also experience an artificial immunity to certain types of damage, usually be wearing certain Rings or Amulets and Necklaces.
