You have a special knack for a certain profession and take to it with ease.
Benefit(s): Choose three character classes. For the purposes of retraining*, you are always considered to have a retraining synergy with these classes, regardless of your current class.
Additionally, retraining any class option takes you half the time it normally would (and thus half the gp cost), though retraining a class still takes the normal amount of time (5 days for a class with which you have synergy, 7 for a class with which you don’t). If you take this feat via retraining or replace it with another feat in the same manner, the retraining time takes twice as long as normal in regards to this feat only.
Can I retrain a feat to replace it with a feat I didn’t qualify for at the level I originally gained that feat?
Yes. As long as the new feat is a valid feat for your current character, you can retrain the old feat and replace it with the new feat.
For example, if you are a 3rd-level rogue who took Improved Initiative at 1st level, you can retrain that feat and replace it with Weapon Focus. Even though Weapon Focus has a prerequisite of “base attack bonus +1” (which means you couldn’t take it as a 1st-level rogue), it is a valid feat for your current level (3rd), and is therefore a valid choice for retraining. (Note: Likewise, the fighter class ability to retrain fighter bonus feats does not require you to meet all of the new feat’s prerequisites at the level you originally gained the feat.)
