additionally, the elemental stinger swords only weigh 5 apiece, which makes them really valuable.
ie: great for opposite element damaging, or for those that have weak elemental resistance, they weigh very little, and they can be sharpened.
while they cannot be improved upon with a melee skill (one handed, 2 handed or with shield), the other items do make up for it.
good combo: weaken an elemental resistance using an elemental curse type, then hammer them with the appropriate sword.
