Empty equipment slots popup tool tip

What is this suggestion related to (eg. Website / Launcher / The game itself / etc. ):

Description:

What do you think should be displayed in the tooltip?

Old earring has a word “Ears” in its description. The same description should be in the empty slot tool tip for this item. Maybe: Empty “SLOT NAME” slot. “Empty earring slot” for example.

Personally i would go for the Empty “slotname” slot one, because its a full description.
