Most Effective Monster

How some people can call Fire Imps heavy :P
They're no higher than lvl 11

If that's not what you mean then you realy need to learn your Bestiary tbh.
It's [wiki]Lava Imp[/wiki] you're referring to if you see them cast Meteor Shower.

As for thoughest one i've encountered so far...
I think [wiki]Lushivahr the Invoker[/wiki] did a fine job in pissing me off and sending my party off to 60% DP

i'l kill creatures of torment mad dwarves even overgrown moles but dont make go after tengu i'm almost sure tengu means bird of death in some language o.O

I hates them! I hates them I do! Stupid Madness Titans!

I take great, great relish tackling these things with my necro, ranger and mesmer (ss, broad head & empathy/backfire respectively) since the nightmare they've given my other characters.

Ruby Djinns, Spark Titans, Shiro'ken Elementalists, Margonite Sorcerers, always die first when I meet them. I guess I just have the tactic of shutting down their offensive capabilities first and then take out the monks.

Save for the Awakened Acolytes and Cavaliers. There's been more then a few times where I thought I'd delt with a group, only to find that a Cavalier resed an Acolyte, that started to bring back the others and then I have to wipe out the entire mob all over again.

Marrow Scarabs are very effective. With their touches and their Well of the Profane they are the bane of all wammos. I loved it when ANet added them to Prophet's Path to spoil that area for all the solo farmers.

Leviathan of the Deep, only monster I know that can do 600 damage a whack, and whacks quite often.

Ruby Djiin's are nothing...BHA and Concusion Shot ftw.

Personally I hate the Diamonds cause they tank like crazy. Not hard, but time consumming.

And Jade Brotherhood Kinghts seems to have a rather quicker than normal recharge on Triple Axe.

And the nominations for most effective monster are:

Prophecies:

• Ice Imps. God, I hate Ice Imps. (Who doesn't?)
• Wind Riders (lvl17.) Cry of Frustration is aptly named.
• Avicarra Fierce. R-Spike hurts...

Factions:

• Jade Brotherhood. Something for everyone! Big AoE damage+KD...
• Dredge Monks. Oh dear, lets hope we get lucky with interrupts...
• Shiroken Elementalist. Happy, slivery, burny Death! Fun for all the family!

Nightfall:

• Sub-lvl20 Monks. Ususally running away before you've even targeted em...
• Stoneflesh Mandragor. Weakness+KD+seemingly unlimited energy pool. Ouch.
• Torment Creatures. Killing machines, even in multiples of one.

And the nominations for most irritating monster are:

• Wurms. Too many reasons to list.
• Diamond Djinn. Slow you down. A lot.
• Rain/Rock Beetles. That sound...

I don't care what you want to say about anything but Beetles ROCK! *sigh* No pun was intended but I realized it before I hit submit.

No the pun isn't about the beetles being "Rock Beetles"...please give me some credit

Avicarra Wise cause me more problems than any other type. I can slaughter all the Fierce and Brave muppets easily enough... but the "Wise" ones insist on Disenchanting me, then kiting like crazy when I give chase to pummel them for their crimes. They're annoying as hell... and serve their purpose in keeping me distracted while the physical-attack birdies kill off the rest of my AI party.

Wind Riders.... just attack without skills and they drop SO easy.
Ice Imps.... no comment. Hell froze over and Ice Imps were born.

The Stoneflesh Mandragor might seem tough... but its as simple to beat as Chilblains > Plague Touch > Spiteful Spirit ... and perhaps a bit of blasting. I consider them "easy" foes... at least compared to those big Craggy monsters that travel in twos and lay the smack down with sandstorms...

Oh come on. Torment mobs are only effective because they're 4/8 levels higher than you, have infinite energy so QZ doesn't bother them, aren't effected by Environment effects and duplicate if your not careful.
They cheat so much they don't count.

Jade Brotherhood get my vote. They're the same level as us and cause so many problems to dumb AI... Dragon Stomp + Triple/Cycline, that and the Power Return spam.

Ruby Djinns are strong... but can be shutdown so easily.

Aatxe don't even count. They're lvl28... its like saying a Tortureweb Dryder from DoA is effective. Its not, it just does 4 or 5 times more damage than your eles do.

Oh yeah, Ice Imps and Avicara Fierce mobs get an honourable mention. Maelstrom is fine until mixed with henchies, then you get a 60dp. Avicara Fierce are just annoying! That Ignite Arrows/Dual Shot spike... if they had a better elite than Practiced Stance to go with it they'd definatly be 1 of the most powerful enemies out there. Imagine them with Forked Arrow, Needling Shot and Prep Shot...

I am predominantely a necro...that being said, Mesmers and dervishes cause the most angst. I go with the dervish beetles, Ruby Djinn (not me or D, but will doa totla party wipe in no time)...Dasha Vestibule was the last mission I got masters on for my prot title...

A deadly trio of fire, Hloy damage Djin and roaring ethers to really make me miserable

Also a nod to the Stone summit between Yaks and beacons' perch...took me a week to find new skills and change my build

With the Avicarra, I specifically meant the ones that always end up ganking you at the mineral springs entrance. Wise can be wanded to death, so they're no biggie for me and Braves can be kited.

When you met the wind riders for the very 1st time, they were irritating, no? Don't tell me you wanded them to death at lvl14?

Stoneflesh aren't annoying in a normal capacity, but their skill chain is an effective one, more so if the change to weakness gets implemented permanently.

Oh and you're talking about the Sandstorm Crag monsters, right? Well, theyre not nearly as annoying if you just flag out the hench as soon as they cast sandstorm - leaving them with just stone daggers. I do agree that the earlier ones with Armour of Earth can be annoying, but degen=gg extra armour.

- Shadow of Fear: They can keep up an infinite amount of minions if provided with corpses.

- Behemoth Gravebane, Scytheclaw Behemoth: Just plain annoying while going through Vabbian territory.

- Sarss, Stormscale: Going through Maishang Hills, it's impossible to avoid his group, and he has single-handedly whiped out my group several times. This goes for a lot of elementalist bosses in Factions.

That's about it.

either Spark of Titans or Shiro'ken Elementists always gave me the most trouble.

Lag. Worst monster ever. appears in any and every zone.

Jade Knights were awful. Just awful. Once you get out of the city, Factions gets much easier. On the otherhand, they teach you how to fight decent warriors.

The Luxon Naga are somewhat tough.

Rain of Terrors are tough, but Prot Spirit and LB Gaze gets them good. Prot yourself and the monks and anyone else critcal before engaging.

Avicara Fierce are extremely annoying. They aren't hard to kill like the other monsters, but they don't deal enough damage to trigger most defensive spells. Then they swarm ya and it's death by numbers. They tear up minions as well.


Regarding Bosses:

Mungri Magicbox is the toughest boss in all of the games. God he sucks to fight. AMAZING healing capacity.

The Ele boss in the NW corner of Poisoned Outcrop...the one with Sandstorm. I simply CAN'T kill this boss with minions. Period. Can't. If he gets Sandstorm off, you're done.

Gwen, she's pure evil I tell ya!

The trick to this boss is to space out your heros using the flags. Place a monk in the center, flanked by 2 SF eles, or a SF ele and a curse necro. It also helps a ton if you get a spawn of the boss, a second crag, and 2 mesas. The first time I attempted this cap, the boss spawned with 3 other crags, and I got wiped out before the first attack landed.

As far as difficult monsters go, I'll give my vote to Josinq the Whisperer. The mob he/she/it spawns with contains a second monk, making this mob VERY rough to take down (at least for me it was).

Yeah most any monk boss that spawns with a second monk is going to be a loooooong fight unless you have the godliest interrupter of all time. A hero interrupter works well but even they can't stop some nasty spells like MoP, which pretty much totally screws you if you aren't looking out for it. They basically end up being one monk healing another monk who is healing the first monk.

I say the Awakened Grey Giants, especially when their heads fall off. XD
