No, just saying you're wrong. The Jeremy NPC allowed you to keep MvP cards and the equipment 100% of the time.
I see, I just read the old thread. So for 192 silvervine fruits, assuming it was an MVP card it would keep at least the card 100%, doesn't say about the equipment but could assume this particular method takes both for 100%.
Either way, there are 4 options and only one saved both, and it assumed it was carded with an MVP card.
