Success
So I actually beat the game, a lot of levels do require ad revives and gem revives/ needing the exact skill combos to win but it just takes time. Some levels (especially the pirate world) you’ll need to switch between a sword and magic user depending on the units they throw at you. I never actually used the archer because honestly their skill select was useless. Just make sure to upgrade your gear a lot and you’ll be fine. Hope this was helpful!
