Continuing playing with the idea of quirks that replace favored class bonuses. So, in honor of Talk Like a Pirate Day
Any character can take this quirk in place of one favored class bonus. Select a weapon. You can treat that as any one specific other weapon of the same type (melee, thrown, ranged, or firearm), the handedness or less (2h >1-h > light), and the same complexity or less (exotic > martial > simple), that does not possess any special rules the true weapon does not possess. You can only treat a weapons as one weapon at a time – if you choose to treat a longsword as a rapier you can use Weapon Finesse with it, but Weapons Focus (longsword) no longer applies. The only thing retained by a weapon when used as another weapon is appearance, qualifying as a god’s favored weapon and/or holy symbol, and the damage type.
You may take this quirk more than once. Each time it applies to one weapon (which may be the same or different) which you may use as another weapon.
