An uvuudaum: can fly. can phase through walls. can survive underwater. does not breathe. has no eyes. has no head. has a thick hide. regenerates HP quickly. can see invisible creatures. does not eat. (*) is not a valid polymorphable form. is a lord to its kind. is normally generated hostile. can follow you to other levels. is nasty. is strong. can pick up weapons and food. can be seen through infravision. does not appear in Gehennom. never leaves a corpse. cannot be tamed.

The uvuudaum is a dangerous monster added in dNetHack, as part of the U "unknown abomination" monster class.

Until the player becomes a demigod (by killing the Wizard of Yendor), uvuudaums will peacefully float around the level, meditating. Even if provoked from their meditation, they will soon return to being peaceful. However, they will cease their meditation once the player is on the ascension run, and will be hostile.

One should always wear a helmet when fighting an uvuudaum, for fear of their headspike attack otherwise being able to instakill the player.

Uvuudaums have intrinsic life saving, though it can activate no more than once every 34 turns. They also heal 25 HP per turn and have 10 intrinsic damage-reduction

Uvuudaums cast the following spells with a base damage of 19d6:

• Psi bolt: Direct damage (capped at 50)
• Spacewarp: Direct damage (capped at 100)
• Stun: Causes stunning
• Paralyze: Causes paralysis
• Time stop: Allows hastened recovery (50–125 HP)
• Temporal duplicate: Creates a clone with timed life
• Nail to the sky: Applies cursed levitation
• Prismatic spray: Multiple large elemental explosions (6d6 each)

Uvuudaums receive +20 to hit, and deal an extra 3d7 damage to curse-sensitive enemies (primarily Angels) and an extra 4d9 damage to holy-hating enemies (primarily demons and undead).

While the easiest courses of action involve avoiding or teleporting an uvuudaum away, uvuudaums can be killed with some persistence and preparation, particularly once the Amulet has been obtained and they all become hostile or (on the Anachrononaut quest, where they are always hostile). Players will need high damage output and accuracy to counteract both the uvuudaum's high regeneration rate and intrinsic life saving. Further, uvuudaums have intrinsic displacement, which means you will have to attempt to pummel one repeatedly to get through.

Uvuudaums also like to retreat to far walls as you chase them making them difficult to kill on levels without an open design. Further, uvuudaums often try to remain a knight's move away, so fast speed to close distance will be particularly useful. On levels with an open design, a player can chase one to the edge of the map and stand vertically or horizontally next to them to force a confrontation. Standing at a diagonal while trying to attack an uvuudaum will often cause them to continue to flee.

Anachrononauts with one or more lightsabers (particularly the Annulus) will be able to generate high damage output enough to punch through an uvuudaum's defenses with melee attacks. Using the a lightsaber style like Djem So, which generates copious counterattacks, can also increase damage per turn. Finally, if seals are known, binding a spirit with damaging abilities and extra attacks could be useful, as long as they do not need to beat the uvuudaum's high magic resistance.

Players should be prepared with several items, including:

• a towel or a high drunkenness level to deal with the uvuudaum's confusing gaze
• several potions of full healing (or, for Anachrononauts, a hypospray with full healing ampules)
• a ring of sustain ability to avoid any attacks that can compromise the player's stats
• above all, a helmet to avoid instakill brain spike attacks

Strange creatures with long, claw-tipped tentacles in place
of heads, Uvuudaums hail from a far realm beyond the known
planes. It is said that they are the lords of those realms,
although evidence for this is thin at best. As with all
supposed facts about that place, that claim is more likely
a gross anthropomorphism, if not an outright falsehood.
The merest glimpse of their form drives men mad, and they
are capable of crushing a man's head with a single flick
of their headspikes. Even if the victim escapes this fate,
their long spikes run with strange venoms.
