Arcane Bond (Ex)
Replaces: Lore Master
At 5th level, an arcane duelist gains the arcane bond ability as a wizard, using a weapon as his bonded item, allowing him to cast any one additional spell that he knows once per day. He may not choose a familiar or other type of bonded item. He may use the hand holding his bonded weapon for somatic components. This ability replaces lore master.
