Suggestion has been instantly declined.
This change would in combination with 100% upgrade chance for weapons from +6 to +7 cause huge problems.
Players would farm lower grade Valeron's Blessing, then exchange them for higher grade ones.
If you have lower grade ones you don't use yourself you should sell them to other players.
For the doubtful case that Valeron's Blessing Grade 33/34 ever become useless, we can add a NPC-price for them.
