This is an annoying thing in DDO, imo.
All belts drop from Amarath quests share the same icon. So does those necklaces.
Spell boost effects share the same icon with spells. (ex: Superior Freeze shares the same icon with Ice Storm. Superior Ardor shares the same icon with Heal).
The arcane spell Jump shares the same icon with FvS's Leap of Faith.
Tons of named gears share the same icon.
Lots of effects share the same icon or even no icon (an exclamation mark).
......
This really should not happen in a quality game.
To me, it is a flaw, or even a sign of carelessness of development.
Developers, you were able to create hundreds of collectable icons. Please give every named item and effect an unique icon as well.
