Until the player becomes a demigod (by killing the Wizard of Yendor), uvuuduams 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 it, for fear of their headspike attack otherwise being able to instakill the player.
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 glipse 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.
