I remember when I salvage something. There is something shows in the bottom right of the screen.
In addition, there were log entries regarding RAD got from salvage and RAD reduced from AD bonus.
Right now, in the log, it only shows one line:
[Inventory Notify] Successfully salvaged Elemental Alliance Ward Ring.
I suspect there is something to do with the RP convert because RP items are also 'salvaged'.
[Inventory Notify] Successfully salvaged Peridot.
[Inventory Notify] Successfully salvaged Amethyst.
