Most Lethal and Most Irritating Non-Uniques?

[Bogatyr]

Umber hulks can be both irritating and deadly in the early game since they melee to confuse and can be hard to get away from since they tunnel.

Yes especially deadly for mages, I've lost a number to those horrible "X"s.

Very dangerous until you have all high resists covered, they often summon more Great Wyrms.

Yes, definitely an irritating one. I virtually always simply avoid or get rid of them rather than trying to fight them.

Irritating: acidic cytoplasms
Lethal: agree with the above, I'd add Death Drakes and Ethereal dragons - both show at level 45, are invisible, go through walls, and can breath light/dark/nether for a fair amount (they have 1848hp)

I find the cytoplasms irritating; at the very least I have to swap gear to get my acid immune item on. I haven't found the other two all that irritating; perhaps I typically only encounter them when I am powerful enough to deal with them.

[Egavactip]

Black Reavers.

Yes, definitely.

For me, I think gravity and plasma hounds are top of list, I have lost quite a few chars when I teleport away from tricky situation into room where there is pack or two of mentioned houds, knocked char out and then slowly killed.

Grand master mystic are real PitA like mentioned earlier posts.

Drolems are killers when they manage to suprise you, and since they are not seen by ESP, running to detection edge is occasionally risky when drolem is out of sight

11 headed hydras in pack are also lethal, as they breath hellfire which stuns

Chaos hounds irritate me, I think, more than Gravity and Plasma. I don't find Drolems irritating, just scary. The hydras are definitely irritating until/unless you can do enough damage to very quickly kill them or you get immunity. But they don't usually come in packs, like hellhounds.

Aranea!!!!!!

Really? I haven't found them that irritating.

1. Grandmaster Mystic
Only because I didn't know about "knocked-out" status the first time I fought one.

2. Ochre jelly
Can't get away from them and they ruin your gear.

3. Gravity hound
If you don't know a pack is in the room you're in, you have a high chance of ending up dead.

4. Hummerhorn
If you don't have pConf, these breeders can spell disaster.

5. Great Wyrm of Balance
Very dangerous until you have all high resists covered, they often summon more Great Wyrms.

6. Magic mushroom patch
Hallucination

7. Nexus hound
"You sink through the floor."

8. Pit Fiend
Summoner able to deal massive damage.

9. Nexus quylthulg
Often teleports you away, cannot be detected by telepathy.

10. Greater balrog
Summoner that often burns up everything on the floor.

Translation: Derakon thinks Aether hounds should breathe only Time, Gravity, Force and Plasma.

Hm. Maybe they should breathe Aether? You know, like a Vacuum only less true.

[mushroom patch]

Hm, perhaps my fear of Aether hounds is irrational. I don't remember ever letting them breathe on me in vanilla, so maybe you're right.

Sounds good to me!

Aether hounds are nigh-totally neutered by having access to every single breath attack, because they pick elements at random. There's a lot more non-threatening breaths than threatening ones, really. In particular, stuff like gravity, force, and plasma is much less dangerous when you're only getting hit by it once.

Aether hounds, chaos hounds, time hounds, and gravity hounds, hands down. Not easy to avoid, often make an otherwise profitable situation not worth it.

Chaos hounds are a pain without resistance, no question, and time/gravity/plasma hounds are all rightfully dangerous, though.

I think Nexus Qs top my 'most irritating' list. All the other annoying monsters are damaging and hard to fight back against, but at least they're something you can run from given the opportunity; Nexus Qs are trivial to destroy but just ping you back across the level again and again and again when you're trying to get to that vault treasure or staircase that you've already cleared all the rest of the monsters from. I have died multiple deaths to frustration because I've just held down the arrow key to fight through a corridor of orcs or something trying to get back to the same corner of the level for the thirty-fourth time. And usually been relieved when I died. (That game where I cleared a zoo of everything but the FOUR Nexus Quylthulgs sitting in there guarding the floor treasure... fun times.)

Hummerhorns are pretty evil as well, because you just can't stay clear-headed long enough to get away. And I actually find Ochre Jellies more of an annoyance than Acidic Cytoplasms - at least by the time you meet the Cytoplasms you've probably got better melee damage, ranged weapons and some escapes, while the Ochre Jellies usually hit you well before you've got the tools to do anything but stand there and get slimed for a few dozen turns of poking it with your pathetic +3 dagger.
