A new feat idea (that actually has a very specific purpose in mind, ie making a Swashbuckler in Eberron capable of becoming a Windwright Captain with only a single cross-class level into Wizard or Sorceror at a sensible level).

Toy with things you little understand:
Requirements: Int 13, Chr 13
Character gains Use Magic Device as a class skill and has a +1 to Use Magic Device checks

Is this balanced? I'm particularly cautious about not making it overpowered, since I'd have to run it by a DM to make my idea work.
