Talk:Upgrade/@comment-138.51.201.234-20140614201617

i've noticed that the price for upgrade goes up while the slime's level goes up. I only use N cards to level up my slimes (because Arcana cards are hard to come by and purchase). Since there's only a maximum of 10 cards I can use to upgrade slime once, would it be better/cheaper to evolve all my one star N cards to HN and fuse 10 of those or to fuse 10 N cards each time to level up my slime?
