Flee
For the Monk skill, see: Dodge.
Flee Rate: Your dodge rating. It is shown as A + B in the stat window, where A is your AGI + any other bonuses + your base LV value, and B is the chance of doing 'lucky dodge', which can even dodge critical attacks. Make note that no matter how much AGI you have, you cannot have more than 95% dodge rate against anything in the game, however this does not ring true inside PvP and WoE Maps, as players can have 100% dodge rate in these maps.
