So, this was recently offered as an option in one of my higher-power games. While I will likely not choose this as my reward, it made me curious on what other players would do with it.
If your DM gave your character a free feat that you could ignore all prerequisites for (including race, BAB, class, and alignment), what would you choose and what interesting stuff could you do with it?
You are allowed to choose stuff like Leadership or Sacred Geometry, though that might be a waste since you can get those fairly easily with normal feats. Also, while prereqs for a feat are removed, a feat can still be rendered invalid by its function. For example, a feat that adds spells to your spell known list still does nothing if you don't have a spells known. Also, you can't use this to take the same feat more times than the feat allowes you to, so no double leadership.
For the purpose of having an interesting discussion, let's ban Spell Perfection from being taken with this reward as well, since that is a bit too obvious of a choice. EDIT: Mythic feats are also not allowed.
(Also, feel free to list multiple feats for multiple characters or builds, as long as it's still one feat per character. Characters still have their normal feats and bonus feats in addition to the feat gained by this reward.)
