I have an aasimar with the metallic wings feat, and was wondering if strength is added to the wing attacks that it grants. It is not listed in the feat description, but it is offered for other natural attacks I have seen, such as razor tusk. Any help with this would be appreciated.
One thing that is included for rule of thumb for TWF and Natural Attacks is based upon the type of attack it is, or where the attack comes from/is used with in terms of limbs.
If the Wings you attack with are considered Secondary Weapons (or Off-hand Weapons), you are still allotted your Strength Bonus, but the amount you gain is cut in half (-50%). So if I have an 18 Strength (+4), I only add half (50%) of my Strength bonus, rounded down (+2).
If the Wings are classified as a Primary Attack, then you add your standard strength. Some Natural/Primary attacks add Strength and a Half (150%) for Strength Modifiers, but are usually listed with the description.
This should cover some ground as to how to add Strength Modifiers to your Wings. As far as what the Wings are considered in terms of additions, I have no clue, and would be wise to ask your GM about it.
Benefit: You gain two wing attacks. These are secondary natural attacks that deal 1d4 points of slashing damage (or 1d3 if you are Small).
You get 1/2 strength on each wing with a -5 to hit, but they don't occupy an of your other limbs or interfere with your manufactured weapons.
