Ok, this is going to be a totally new development in the world of wizardry that is just about to be perfected by a Professor at Whirtlestaff's (to be named more specifically later). He's SURE to be awarded Tenure for this one, too! Our wizards will hear about it soon enough in Quail Valley, from Magus Crus, who is in touch at times with Professor "Jack" Claret, among others. So, I don't think you get a feat at 5th level, so this won't even be a problem now. But, if you want to take this feat later, you'll need to return to the Whirtlestaff's campus, and learn it 'at the feet of a master' ('feat of a master,' quoth sd) as it were.
