Jumping

Jumping is a property that allows a player to traverse multiple tiles in one movement. The extended command #jump allows you to perform this. The ability to jump comes from three sources: being a Knight, wearing jumping boots, and casting the jumping spell. Knight jumping and jumping from the boots are practically identical; the only difference is to which squares you can jump. All sources of jumping require that you see destination tile, and all sources of jumping consume d25 nutrition (in addition to any spellcasting hunger penalty) and render the player immobile for one full turn (not simply one move) after landing. The jumping spell allows you to jump farther than you could if you were a Knight or wearing jumping boots; just how far depends on your escape spell level.

In the following diagrams, tiles to which you can jump are marked by an 'x'.
