I had to skip the tutorial, because my team killed the 3 enemys off before I was able to cast the spell. In the next fight the game asked me to cast that spell but I haven't had enough energy (or whatever it's called) and there was no "Done" button. So I lost my bonus. So if casting that spell is required, make sure we can at the point we are originally supposed to.
now im just spitballing. but i just went throu both tortoirals. i like them both equeal. but the combat jusat a smig more. why dont you find a way you tell all the rules then put them into a real combat?
