[scantraxx7777]

Hi, possible to make different enchant rate for Mage/Fighter Weapons ?
As i found in internet : Mage success : 40%, Fighter : 70%

 <!-- Scroll: Enchant Weapon (S) -->
    <scroll id="959" infallible="false" on_fail="CRYSTALIZE" chance_bonus="0" grade="S">
        <levels min="0" max="20" />
        <items_restrict type="WEAPON"/>
        <chances type="WEAPON">
