So from 3 crystals to 25 crystals to 120 crystals for guaranteed Nico!!!!! No one’s gonna by that I think the AI used to make that offer is a little broken lol.
Oh yeah it rolls over but that’s still a massive cost
Update:It appears you can tap on the crystal itself and then select a “Details” tab to find out how many crystals you have remaining for each guarantee. This is a good feature that provides the detail I suggested above. Dr. Zola
