I made the mistake of not reading a feat guide before starting and selected Improved Initiative for most of my characters (amongst other apparently useless feats). I'm currently at the fjord so not that far and I really like my current party setup.

Is there an item later in the game letting me reroll or I need to use an editor to remove and replace some feats?
I guess I could also restart, I just really really dislike Targos.

Use Dalekeeper 2.

Thank you for the suggestion, this will be handy If i ever mess up again!
