The percentage after the weapon power is Weapon Block chance. If a character has the Weapon Block R-Ability equipped, this percentage is added to his or her evasion.Originally Posted by Russ80
In case you were wondering, the equation for determing a character's chance to evade is:
1 - [(1 - C.Ev.) * (1 - S.Ev.) * (1 - A.Ev.) * (1 - W.Ev.)]
Where C.Ev. is the character's innate class evasion, S.Ev. is the evasion stat of the character's shield (if equipped), A.Ev. is the evasion stat of the character's accessory (if equipped), and W.Ev. is the evasion stat of the character's weapon (if the R-Ability is equipped).
