Hole

A hole is a trap, but it is always visible. Holes, like most other traps, show as ^ on the screen. Sometimes a monster will intentionally jump into a hole to escape.

You can zap a wand of digging downward to make a hole, dropping you down a few dungeon levels. If a monster has a wand of digging, it might zap it downward as well. This can be annoying; whenever you find that dwarf, it makes another hole, and when you finally kill it, the wand is empty.

You can also dig downward with a pick-axe to make a hole, but that is very slow, and not useful for escaping monsters. First you would make a pit, and if you dig more it becomes a hole.

Zap your wand or apply your pick-axe, and press [>] to fire it downward.

Some dungeon levels are made of hard material which is undiggable.

Creatures of size "huge" or larger will not fit into holes and can walk across them. Flying creatures can also traverse holes.

Holes in Sokoban are special, and have air currents that will pull you into them even if you are flying or levitating.
