Killing someone is allowed as long as no one sees it.

Although it is geometrically impossible and ridiculous, rotating a piece will both alter the configuration of the piece and teleport the piece translationally.

I learned that while you may be able to command the elements, you can still only have exactly 15 items of equal size in your inventory and in terms of size: 30 herbs = 30 potions = Short Sword = Sol Blade = Fairy Ring = Chain Mail = Running Shirt.
