Hello,

deconstruction of any crafted item into most of the mats, with some exceptions of course. the higher your skill the more mats you are able to recover.

upgrading existing items, even non crafted. 2 or 3 enhancements can be done, for example: any sword, gets sharpened hardened and lightened.

deconstruct even non crafted items in an attempt to recover some prized material. i.e. cambrinth pumpkin with glaes butter.
