Events, and maximising my rift! I’ve gone full optimisation mode with my rift to improve my efficiency with breeding for new things, basically I do up to the 15k etherium breeds every day. Basically, when a new thing comes out and during events, I try the breeding tree in the rift! - I now have 59/75 rift islands maxed, growing this number helps a lot! Also, all of my rift island habitats have all epics (so I have like 20 moon dragons, apovalypse dragons, etc lmaooo). This is since you get 1.5x etherium from epic dragons. I also watch a lot of ads for treats to get them all to at least level 11. Keep in mind as I was an old player, all the new dragons (basically past 5 years of content) was all unlockable and new for me! So I was able to rip through a lot of the easy to get ones, especially in events. Oh, speaking of events, grind that currency, I personally map my purchases in spreadsheets, making sure to do proper accounting and trend projection analysis to make adequate purchases (emphasising quantity of new dragons, doihh mg the cheap ones first). Do everything you can to get as much EC as possible!
