I have been around the block, with MMOs, and the system of ‘chance based item upgrade’ usually comes with a cash shop item. The cash item protects the in game item, being upgraded, from adverse effects of the upgrade attempt… like preventing the item from perishing.
In Eve’s case, I guess, the item from receiving a negative bonus?
Was such an item announced, for the cash shop?
If not, I have already horded a lot of PLEX and please introduce it soon!
