Ok you do this after your at the academy and your training against whisper when your older. After you beat don't go over to archery wait there and a guy will walk over talk to him, you have to do another fight and then you get a Katana. After go to the archery do the lesson and stick around after complete the challenge and you get a crossbow. Next go to the next place and
drop the lesson stick around do it again and you get two ressurection potions( I think ) or mana potions either way it's good.
