Impervious
From D20advanced
| IMPERVIOUS | +1 Modifier |
|---|
A saving throw with this modifier is especially resistant. Any FX with an effect modifier less than the Impervious resistance's bonus is resisted automatically (that is, the saving throw automatically succeeds). So, for example, Impervious Toughness 8 automatically resists any Damage with a bonus of +7 or less. Penetrating FX can overcome some or all of an Impervious resistance.
Impervious is primarily intended for Toughness resistances, to handle characters immune to a certain threshold of damage, but it can be applied to other saves with the GM’s permission, to reflect characters with certain reliable capabilities in terms of resisting particular FX or hazards.
