I think I know the answer, but I wanted to get clarification.
Can the Returning Weapon spell be placed on a melee weapon, giving the returning ability to that melee weapon? The spell does not say it cannot be placed on a melee weapon, but it does say the spell acts as returning weapon quality.
Obviously, the returning weapon quality says it can only be placed on a thrown weapon.
I just wanted to make certain the spell was not granting this to a melee weapon despite the returning quality decription.
