Flying is an intrinsic property that appears in NetHack, Monsters that fly are defined in the source code with the M1_FLY flag.[1]

Flight allows a monster to avoid contact with the ground as with levitation, but additionally allows control over vertical movement - while flying, you can pick up items on the floor, go down stairs, use ranged weapons without hurtling in the opposite direction, and so on. Broadly speaking, flight gives almost all of the benefits of levitation with none of the downsides.


The detailed effects of flying are as follows:

You can sometimes displace flying monsters by kicking them. If the "foo swoops, nimbly evading your kick" then it is moved to a vacant square randomly selected from those nearest to you.[2] This means that on sufficiently crowded levels, it is possible for a flying creature to swoop through a wall. (This is possibly an effect of bug C343-38; it is hard to tell from its description.)


The amulet of flying is an item that originated in SLASH'EM and has since appeared in many variants.

Various new flying races and monsters (and thus additional polyforms) are often added in variants - the vampire player race]] has intrinsic flight in all variants.
