Unmagic worm mass
Eilinel the Entrapped
Eol
A great Wyrm of the Nexus
A great wyrm of thunder
Maedhros
Great terror wyrm
Young wizard of the high Council
Harrowen

I don't know Un, but if it is anything like vanilla, then you need to be very careful around those areas which you need to dig open inside the vault, especially those single cells.

Most of those monsters didn't tell me anything, so can't give any specific advices. Just general, be faster than they are, be prepared to escape, don't deal with several monsters you don't know anything about at same time.

It would be helpful to see your equipment and damage potential, too.

In any event, always remember the first rule of Angband: it's better to run away and live, than to get greedy and die. (Getting greedy and living is, of course, usually your best option...).

Been very careful, digged round corners. cleared only left part of vault, tping monsters which were too dangerous. Results are 5 artifacts, 4 greater runestones.

Oh... The first item dropped in the Vault was a Mace with +20 damage and a ton of slays. greediness pays
