Upgrade all, plain and simple, hahahahahah

Leave at the end or dont upgrade your 20M certificate the increase of that treasure is just 1% each lvl, its your call but I prefer to upgrade the ones that have the biggest % increase per lvl

you are so lucky, I already spent more than 900 crystals plus a lot of tickets (great and supreme) and never got any crystal generating treasure not even the A-rank one :'(
