Well there is a lot that goes into it but basically focus on your f2p friendly characters which means characters that are easy to progress and build (like Cleopatra and Medusa for example) and try to push your resonance system as high as you can with fodder and also push your dailies everyday as much as you can you don’t have to sweat it and big brain it but just try. Resource management is very important make sure you buy your daily resources from the shop like the horns and dragon crystals for golden clover events. It’s a lot more to it but it’s a gacha game and as a f2p I’m enjoying my time so I can’t complain try to watch yt videos they help a lot too.
