Just Use Guts
Berserk Tips and Tricks
Through the vast majority of Berserk and the Band of the Hawk’s story you’ll have control of guts, but there are points where you will have the option to play as a few others. Ignore those options. Yes, it’s tempting to try out something new, but it will only do you a disservice in the long run.
The reason for this is that only the character you play as earns experience. However, you can use the gold you collect while playing Berserk and the Band of the Hawk to bring your other characters up to the same level. With Guts being the main character for most of the game, he’s definitely going to be your highest level, so it makes sense to continue building him up in order to save yourself a grind later. Also, he’s the only usable character in the last few missions, so he deserves all of your attention.
