%w.att,? Total Damage % ? huh?

Would need confirmation from dual bladers. Boss damage on one dagger or katara should give both the boss damage bonus, meaning you only need one piece to have it. ATTACKS is modified before ammo/star and attack buff, so basically just your "base attack" that you can gather from your equip/blessing/skill. Meaning it should be (base attack x ATTACKS % + (ammo/star/attack pot/buff), then modified by echo after. Total damage %s stacks, so ideally you would want 30%, total damage, total damage, total damage, ATTACKS, ATTACKS, spread across dagger and katara, order doesn't matter but of course having total damage on first line is a bonus. Reason why you don't want % luk is the increase in less compared to total damage and ATTACKS once your % luk gets higher. Since you don't boss a lot, I think having 3 total damages, and 3 ATTACKS across is better. If you use apples or high attack pots a lot (or your weapon att is considerably low, say 150 ish), 4 total damages and 2 ATTACKS might be better.

I don't understand what ATTACKS mean, mind clearing that up? and I couldn't further read since it all had ATTACKS calculated in..

So okay maybe I boss once a week, but why get 30% boss damage just for that? when I'm going with a party for zak (example) my damage won't be that noticeable..
On the other hand, when I'm training solo at skele/RooB4 my damage can help a lot to speed up training and get me more exp overall.
So basically, I should wish for % boss damage and % total damage even if I'm not bossing a lot?
