Hello guys, I've been playing the game since ~3 days ago and I'm not sure about what to focus on first when leveling up. Anyway, here are my questions: 1- WHAT IS THE BEST WAY TO SPEND CRYSTALS? 2- WHAT IS THE BEST WAY TO SPEND COINS? More specifically if it is worth it to use them in bronze or silver characters 3- WHAT CHARACTERS DO YOU RECOMMEND? I saw some posts saying cold stones and the bronze rank cerebella with light nature are nice and worth to make them gold rank, but I wanted to know good options for the other characters as well, specially Filia. And while talking about specific fighters, are red velvet, bad ms frosty and temple tyrant good? As for the bronze rank, are bad hair day, twisted mettle, icy hot, heavy reign, rerun and In Denile good options? 4- IS INVESTING IN BRONZE CHARACTERS BETTER THAN IN SILVER OR GOLD ONES? I mean, they are a lot cheaper and you could upgrade their skill tree way quicker and for a cheaper price since they're originally bronze, whereas if you're upgrading a gold or silver one they'll be more expensive even though the only difference between them is, correct me if I'm wrong, their passive skill.
