Square

A square in NetHack is a single space on the screen, in which a single ASCII character fits.

Each square can hold:


 * One monster (including you)
 * One dungeon feature
 * Unlimited items

It is impossible to have two or more monsters or dungeon features on the same square. This is a fundamental rule of roguespace.

If multiple objects are on the same square, the symbol for the topmost object is shown. The order of objects in the pile can be seen using the look here command: [:]

The floor on each square has one of several terrain types, which affects how you move through it:


 * Room
 * Corridor
 * Ice
 * {{blue| } }} Water
 * {{red| } }} Lava
 * Cloud
 * _ Air
 * _ Solid rock
