Big Goron's Sword from Zelda: Ocarina of time. That thing was so easy to get and just means that you win after you get it.
I have literally used that to lay siege to Evergreen Mills and Tenpenny Tower(though technically nothing happened to the latter). I won many, many times.TestECull said:Experimental MIRV by far. Eight mini-nukes, no telling where they'll go, but who cares? Once you've got this thing they might as well roll credits, 'cause there ain't a single baddie left in the game that can stand up to you.
