I thought you could use a maximum of 25 joker orbs to put stars on dragons, however looking on some of my dragons that's not the case.
I can put a third star on a dragon using the last 48 orbs needed as joker orbs. I've got confused when I saw another dragon with no stars on it and I couldn't enhance it even when he needed only 28 more.
Does the maximum number of joker orbs you can use to enhance changes with the number of stars that a dragon already has?
If someone who truly knows how that works could shine some light here, I'd appreciated.
