Yeah, the Fierce Deity's mask, transforms Link into an adult form that wields a double helix sword. It can only be used during boss fights, but when you Z-target the boss you can just swipe your sword and this blue disk will fly out and hit the boss, it uses magic to do that though, be careful. To get it, you have to get all 24 masks and trade them in during that freaky endgame part. Then, you have to talk to the last kid and he'll give you the mask, it makes the last fighs pathetically easy.
