EQ:Int casters
Int caster = Wizard, Magician, Enchanter, Necromancer. Intel is the primary stat (determines mana pool capacity) as the primary means to accomplish anything is via casting a spell of one sort or another, and usually at a range. Intel casters are restricted to wearing silk armors (lowest Armor Class), suffer the lowest skill caps for defensive & offensive skills, and have the fewest offensive & defensive abilities.
Int casters are offensive at their core, and receive the least amount of health points gained per stamina statistic resulting in the lowest possible overall hit points.
Besides the 4 primary Int casters, Shadowknight utilizes Intel stat as the base for casting spells.
