Most Effective Monster

(I'm not sure if this belongs in the lore forum, but I'm less sure where else it would go.)

Saying we fight a lot of monsters in Guild Wars is like saying the sun is kind of hot. Most of them get smacked down by a competent team without incident, but there are always a few that we see coming and go "oh crap".

Most of the very worst have special monster skills (Glint), or have attributes jacked up way beyond our own capacity (Rain of Terror), or travel in multiples (Arm of Insanity). But some aren't too far removed from builds available to you and me, and it's those that I want to consider for the Most Effective Monster title.

Myself, I'm torn between the Ruby Djinn and the Jade Brotherhood Knight. The knight really has a lust for casters and unleashes devastating axe-based AoE. However, the djinn slams waves of damage into everyone AND sets them on fire. Also the djinn shares a skinn with the terrifying tinkerbells of Sorrow's Furnace.

How about you folks? What monsters in any chapter really messed you up but good? Feel free to also consider monsters that you considered overpowered for their place in the storyline.

Ruby Djinns are indeed scary, I'm forced to equip fire defensive skills like mantra of flame, specifically to deal with them. Besides that, those damn Avicara Braves in Mineral Spring are a slaughtering squad... and Ice imps, i hate ice imps.

Fire Imps gets my vote. Those are some nasty villains. They just kill you with Mind Burn and traveling with those titans makes them that much more potent. I hate them
Another group are those damn spiders and their interrupts and burning on Ring of Fire Island mission

Abaddon's demons are the only things that have ever killed me when I alt-tab so I guess I'll vote for them.

Spark of the Titans - love those little beasties.

I think the Wardens in Echovald Forest - the groups normally contain a nice mix of warriors, rangers, healers and mesmers...a potent combo.

I think it goes without saying that the monsters in the DoA are the absolute most powerful. However, this is not fair to answer with them as it is an elite area. If you're talking about non-elite monsters/non-bosses, I'll have to go with the Titans/Charr Lords during Titan Source (4 man party is a killer) or the Torment Creatures (that Call to the Torment means any mass AoE or teams that don't use coordinated spikes end up making mobs bigger rather than killing them.)

Any stupid birds (lvl20 and up) are the biggest pain, I think.

Dredge Gardeners.
I wished the factions henchie monks were half as effective.

Well not much can touch my dervish but one thing that puts the fear of Abbadon into me are those damned Rain of Terrors. They spike extremely well in groups of two or more and even with the interventions and a full spread of regen from Mystic regen I still have to really struggle to stay alive.

if we are counting UW/FoW then id say Aatxes, Shadow Rangers (Barrage on a AL 60 char is just nasty)

Now in non-elite areas id say Any of the Crags (huge ele dragons, use sandstorm) and the other guys they are almost always accompanied with the Shambling Mesa. EVERYTIME i go up against a group with both of em in it, a party member always dies (heros/hench)

Them dwarfs outside yaks, when your a low level! Empathy is not funny when your only been playing for a week or so

Most of the ele bosses in Factions.. they hurt!

Ruby Djins get my second vote though, I don't kite fast enough for them to not do lots of damage.

those avicara fierce have always been a pain for me

imps, annoying bird creatures, stuff that clones

Any monster that uses call to the torment is a real pain to deal with as the extra amount of time it takes to deal with them might result in a 2nd wave of enemies to close in on my team and I.

-Fire Djinn / Roaring Ether (especially bosses)
-Rain of Torment
-Dredge Gaurdian
-Shiro'ken Elementalist
-Spark of the Titans

Kormab burning heat.. or whatever its name is in the hidden city of adashim (spelling) To over powerd can wipe a team of 8 in the blink of an eye if you dont make sure your team is spread out

Fire Imps, not spark of the titan have my vote, haing 2-5 of them trowing meteor storm at you then spamming mind burn is incredibly annoying.

The bunny outside Ashford Abbey in Presearing :P

Kournan Healers. Simply for the fact that they cause so much gnashing of teeth for so many about the running A.I.

But my vote goes to those paragon demons that replicate themselves and others. They're a must kill first target.
