Immunity
Type: P Action: Auto
Range: Self Duration: Always
A critter with Immunity has an enhanced resistance to a certain type of attack or affliction. Effectively, the critter has a Hardened Armor rating equal to twice its Essence against that particular kind of damage (see Hardened Armor , p. 397, CRB). This means that if the modified Damage Value of the attack does not exceed the Immunity’s rating, then the attack automatically does no damage. If the modified DV exceeds the Immunity rating, perform a Damage Resistance test as normal, adding the Immunity rating to the dice pool for this test. Additionally, half (rounded up) of the Immunity rating counts as automatic hits on this test.
Some Immunities function slightly differently, because the attack they protect against doesn’t do damage, per se.
Immunity to Age: Some things don’t get old. Literally. Beings with this Immunity neither age nor suffer the effects of aging.
Immunity to Normal Weapons: This applies to all attacks that are not magical in nature; weapon foci, spells, and adept or critter powers function normally. If the critter also has the Allergy weakness, then the Immunity does not apply against non-magical attacks made using the allergen.
