Mage / Thief

This multi Class offers the basic Mage and Theif skill lines, one Proficiency point allowed in all weapons and fighting styles available to thieves, and all Mage Spells may be learned regardless of school. Note: Gnomes are the only race to have access to a kitted mage class, and the extra spells per day of a kitted Mage, however it is restricted to the Illusionist so you lose the Necromancy school of spells, apparently Gnomes dislike Halloween...

Equipment Idea: Combo Robe of the Arch Magi, Balduran's Cloak, Ring of protection +2, the Ring of Wizardry, the Amplifier or the Amulet of Power, and Green Ioun stone, Belt of Inertial barrier, buckler +1, and Darts/ Throwing Daggers, single handed weapon for higher defense. For more reliable offense, short bows or crossbows. you'll end up with 4 proficiency points at the level cap for BG:EE and The Black Pits, so you could combo any of these options with ease.
