Dr.Hadji said:Whats so stupid about having the new ability you trained with during the entire dungeon be used as the litmus test on the boss? Knowing which weapon to use doesn't make the solution any more or less obtuse.
In the NES LoZ, there were several ways to beat the most of the dungeon bosses (which is why you can get to Ganon without even picking up a sword!).
At the least, there needs to be variety so it's not "do this 3 times and the boss dies!" for every boss in the game.
