So I'm on level 2 of the Swamp and I came across my first Rougaru, and it wiped the floor with my wolves. Two of them are at level Skull Crush, but the other three are at base level and level 2 battle.
Do I just need to keep replaying lower levels on my weaker wolves, or is there something else I can do? It seems like a waste of time to keep replaying, especially since you can only explore once per hour.
