my idea i saw this things on custom specil attackes well howbought something like this alternatesword choices for example you could chose between
Mace
Sword
Fist
Staff
stuff like that player could make the gifs they would do the same damage just diffrents gifs and actions as you swing them like fists you would get gloves and you could hit harder (wow i actuly didnt post something usles)

sort of like Diablo?

This idea was already suggested a while ago.
