In Infinity Blade 2 for the iPhone and iPad, there is a chamber in the castle known as the weapon chamber or the dead king’s chamber.
There are symbols in this chamber that signify specific weapons. Owning these weapons and bringing them to the chamber will open a door giving you access to powerful items.
