No Parameters 

Returns r2 = 0x00 if Attack Hits and if Ability is not Evadeable

Set the 4 Ability Evade bytes
 - 0x801938de - Accessory Evade
 - 0x801938df - RH Evade (weapon or shield)
 - 0x801938e0 - LH Evade (weapon or shield)
 - 0x801938e1 - Class Evade
Set Ability Base Hit to 100 (0x801938dc)

Modify Evade bytes and base Hit according to Statuses/Ability/Facing/Weather etc..

Roll Each Ability Evade byte against Ability Base Hit
(So something halvering Ability Base hit, will in fact doubles all Evade bytes)
