WONDROUS ITEM

Wondrous items are not appearing on character sheet page. 

Do you mean in the manage equipment pane when filleting by Wondrous Items? I'm settin Wondrous Items in my inventory. 

when you try to add wondrous items to a character through manage equipment you can only add it if you type it in. 

Is it possible to have stages for legendary, wondrous, and artifact magic items?

Example being that you unlock more effects and abilities from a magic item over time as you level up.
