Something Weird.

The El Nath Challenges when u get into a battle , the werewolfs one where u have to fight them to cross the stairs , you can actually use escape 4 and skip the battle . when you do that , u can just go on with just escaping. Simplified : The El Nath Challenge , When you fight the werewolfs placed on the stairs you can just escape till the boss , the crystal i have no idea if it's a bug or something just putting it here incase feel free to move it to the correct section

I think this is known already. Including Zeru....

There's another secret to this challenge too...

anyways its been known for a while so either Zeru forgot or is too lazy to fix it, or he's completely fine with it. Consult him?

Its part of the game, same thing with the crystal transportation save.
