Paralysis Skill and Medals that deal damage based on Paralysis

[Oathkeeper]

Is it efficient to give the Paralyze skill to a medal that deals more dmg with that status effect? I dont know if the debuff is placed before or after the medal attacks, (I have seen str debuffs/buffs applied before the medal attacks) but I have a few medals that I could use in place of Hades (I'm thinking Vexen maybe) but I have almost all attack boosts on all the other medals, so none of them have the paralyze skill to pull off before Vexen

You need it to be set to the medal(s) before as it doesn't activate until after being hit.

oki ._. Well at least I can put that to rest. Vexen would benefit from the reverse bonus from my keyblade, but Yuffie has more orbs than him, giving her a higher %. I'll just crunch the numbers then.

Is it Base + Keyblade bonus x multiplier + guilt%? (and how do you add atk boost skill dmg?)
