No need to worry about the arcane spell failure thing. Read post 93, it should explain. Also, you still have listed "javelin of lightning +2", "Crossbow +2", and "Oil of Magic Vestement". Those are under the 'don't buy' heading. I'll be providing you with your offensive and defensive items. Just tell me what kind you'd like...
Offensive examples: Sword, 2 weapons, staff, crossbow, javelin, etc
Defensive examples: Armour, bracers, amulet, shield, etc
