yes* you will gain 40% pen every attack, but each tracks separately so the final dmg still triggers after 5 attacks, it just triggers twice.
Ok, thanks so much. really helped!
What happens if you gain more than 100% pen then?
Nothing special :D
Reducing Def with debuffs like Karakai's Active Ability Shrapnel Blast, can increase damage if Def goes below 0 tho!
oh
The bit about negative defense is cool tho!
