A bebelith: can survive underwater. has no hands. is an animal. does not eat. (*) is not a valid polymorphable form. is normally generated hostile. can follow you to other levels. is nasty. has infravision. normally appears in small groups. may turn against you when tame. cannot be tamed.

The main threat presented by bebeliths is their armor-disenchanting shred attack. If a piece of armor is disenchanted to such a degree that it it's net AC bonus is 0, the next shred attack which hits that armor piece will destroy it. Artifacts are immune to destruction by bebelith shred attacks, but not disenchantment.

Bebeliths follow the same movement rules as grid bugs. Players can therefore use positioning to kill them without taking a hit.

‘Long we live and long we weave
Till we have filled this space.
Then, as before, we will leave
To hunt another place.
Our task ends when the weak are gone.
then fill new spaces with our spawn!'
