[DF] Resistant to Evil Supernatural Powers

[Bruno]

Resistant only gives a bonus to Resistance Rolls.

Should an area or missile effect give you a Resistance Roll, it will give you a bonus on the Resistance Roll. It won't act as DR against generic magic, and it won't give a bonus on Active Defenses.

I would, as a GM, allow a +200%-ish (not decided on the exact value) modifier to allow you to apply half (round down) the bonus to all your active defenses against Evil Supernatural Powers, should you get an active defense. "Immune to Evil Supernatural Powers" would be treated as +15 in this case, giving a +7 to active defenses against Evil Supernatural Powers.

Half bonus on the justification that a resistance roll is against full attribute, whereas active defenses are based on half skill or half attribute (or two half attributes averaged together, in the case of Dodge).

A bonus to active defenses is Defense Bonus* (Limited, Evil supernatural attacks, -40%; PM, -10%) [15/level], so your modifier would need to be +300% for Resistance +3 or about +850% for Resistance +8 to be a fair price. It's probably better to just allow properly limited Enhanced Defenses as a Holy power (in addition to mundane options).

* Enhanced Defenses meta-trait from GURPS Supers, p. 34.
