I dont think this game has many. Scholars can give us a skill speed buff
we give piercing resist debuff
warriors give slash resist debuff
monks give crush resist debuff

i think that may be it. I was under the impression (not all that much testing ill admit, but it seemed consistent) that all enemies have 0% pierce resist, so taking them to -10 gives us ~11.11(repeating) more damage to them with our piercing attacks
