ToME WikiKhymChanur: In 2.x sound resistance provides resistance against stunning by other damage types, like plasma and ice. It might be interesting to make it so that sound resistance only keeps you from being stunned by sound, so the player will need to find a generic source of stun resistance for other damage types. On the other-hand, doing this would require us to add stun resistance to various items, egos and artifacts in such a way that players will get generic stun resistance at about the same clvl/dlvl as sound resistance, so it might not be worth the trouble.
Orvin: How about granting generic stun resistance only when the player has all of resist sound, resist confusion, and free action? This wouldn't require adding a new resist type to objects, but would also have the effect of granting stun resistance at about the same level as sound resistance.
