Hi, I'm kind of struggling to obtain a max boost crystal. Spending Gems to Max Boost Crystal from Shop is not a good option for me. I found a several way to get it. However, I can only get few Max Boost Crystal from example Daily Kill (3 pcs Max Boost Crystal), Zenith Rewards (thru dungeon) or last option Creating and Deleting of character to get a Max Boost Crystal. Is there an easy way to get it like farming dungeon or something like on 5th Anniversary dungeon?
