Coromon
- It takes a while before the game explains the mechanics in detail, so don't worry too much about the long term strategies and keep playing at least until you get the second pile of books from the Hayville library (unsurprisingly it's mostly just Pokemon).
- Solving the library quiz gives you an XP share item (lazy gem) which is handy to keep your benchwarmers leveled up. The second library quiz gives a sloth gem which is even stronger. There's another early sloth gem hidden in Donar Island.
- You can reallocate the potential points later, so no need to worry about those too much, and the game isn't too tough on normal difficulty anyway, so some extra grinding or rethinking your squad works if you're having trouble.
