ok so i deleted my old one to go in deeper on what i mean,
-the wolf boss is grindy plus after you defeat it the second phase happens and you dont get your team revived making you grind more. which comes to my solution you could add items which caused your attacks to do over time effects or debuffs which make it easier, also reviving your team to make it more fair since the boss can also revive itself.
-my second idea is where we dont get our team revived but you add a different character we can unlock and also give us more exp boost items to help with the grinding at least. my idea for the character is a lizard type girl. also great game
