I don't know if item classes is what Sverkerman meant. I still think it was a wierd request, though, since none of you have any idea how the game actually plays out.
The current item classes are: (each one has 4 slots)
•"hunting loot" (unnamed)
This is the inventory. As simple and noob-friendly as it gets.
Click one to access one of the inventories.
Note: The text "weapons" will be changed to "equipment" and the "berries 2" slot will be replaced by "hunting loot".
If you can, though, a name for "hunting loot" would help greatly. Basicly it is what drops from killed creeps, like furs, blood, horns etc.
