I suggest having a feature that Pandora or, with the future jeweller skill we have been hearing about, could “pacify” a level 3 or 4 gem that a character has, to make it tradeable within that same account, similar to what you can do with vitality coins.
This feature could cost something like 250 dusts (half of what is costs to seal a level 5 gem.) That way, you wouldn’t want to trade the gem around unless you were sure of using it there.
It’s already hard enough to level a gem to 3, that having a lv 3 or 4 jewel stuck on a character you dont play anymore is quite frustrating.
Let me know what you guys think about the idea.
