1. NP Damage only increase NP Card damage, also different buff multiplies while same buff is additive.

2. No. Arts only increase Arts. Quick only increase Quick. Buster only increase Buster.

You might misunderstood it with NP Generation rate and Star Generation rate. Arts and Quick buff increase both as well (albeit minor) due to nature of their card, while Buster nature is pure damage, so it'll requires 100% Star-Generation rate or 100%++ NP Generation rate to score with it.

3. You mean things like Buster resist down? No. Its to each respective card types.
