I’d like to know how to get past the third shortcut. I can’t seem to win against all those monsters! I come close, down to the last few dreameaters but they put Godfeather to sleep and that marks the end of that.

When is the Dungeon Challenge gonna be open again?

Locking this thread since it’s been bumped, question has been answered in the other one.
