Cleaned Dungeon:16 and found the entrance to Vault, just peeked an eye on Vault:1 and the "blinking centaur" Nessos was near the stair, i threw him a fireball that took 1/5 of his health, while he shot an arrow that took half of my life.
Damn, should have launched mephitic cloud before, i always forget that spell.
OK, so after Shoals and Snake Pit, i cross Vault from my branch list for now.
That does not really leave me much choices but the near-stair areas of those 3 branches are just way too dangerous, uniques and strong monsters near the stairs are a big no no for my low healthed kobold.
Found another pesky unseen horror in the open, it allowed me to make sure 2 of my unidentified rings were not allowing to see invisible.
Only thanks to a controlled teleportation near a corridor and then sticky flame once possible directions were reduced to 2 that allowed me to see the thing and kill it.
While cleaning the floor, Sif Muna awarded me with a book that finally got Blink in it, it's been a long time i hoped to learn that spell.
Unfortunately, no controlled blink spell in there.
Dungeon:16 was really hot, a few centaur, a few centaur warriors, several skeleton warriors and 2 hydras.
Took me a few hit&run attempt to get rid of those dangerous foes for my low health.
Controlled teleportation is definitively a life savior.
I hope to find very soon a few identify scrolls, it's been a long time i have not seen any.
I have a few scrolls i can't know what they do, several potions i have no idea about, and some rings and wands that does not seem to shoot something.
