penetration

please i really wanna know. does anyone here know the convertions of penetration to attack, amp, CD??? like 5 pene = 1 amp?

I heard 50 pen = 10 amp

results are going to vary quite a bit from character to character. generally speaking you can use costume slots as a guideline (20 attack vs 10 pen vs 2 amp vs 4 cd). ultimately your lowest stat amongst the 4 is the one you should improve on most. slot efficiencies is a whole extra topic that i'm not going to bother going into

I put on a penetration sienna bracelet that had same amp as a prideus ... and the only difference i saw was 12 atk on impact stab.
