Hello everyone! I am a returning player, was wondering if there are any guides or info for some of the following…

1. How to get souls for battle pass characters? I know there is a small chance to get them via chests but are there any other way like events etc. Also I know you can buy them in the shop but why are they so expensive???
2. Ways to get gold coins?
3. Good spells
   Thanks!
