Can someone please explain to me the meaning of the various symbols - little closed triangles like arrowheads, and open larger (but still small) triangles - which are sometimes attached to the beginning or the end of a particular item name? The pathetically slim manual provided with the boxed retail game omits any explanation of these symbols as well as many other features of the game. Why is there no detailed online help within the game itself?

It means the weapon/armour is better then the current one, in terms of defense. But ofc your armour may have 100% faster mana reg and the other don't.

Dont think enchants are taken into account on this though
