I am making this post to add info that I gather from GMs (or game) and will state which source is was for clarity, for peoples searches:
* Cant make a Magi Robe act like a vamp robe (make the hood adjust via double clicking) via the Item ID/ED change. (per Dante)
* Cant make an item have more then +20 LRC. I asked if an item that already has +10, could have +20 or more. (Per Dante)
