Megrima the Plaguecaller  

I've been camping this zone for days now. Only seen Megrima twice. 2nd time I was just running around killing other named mobs and I had just been by the crypt two minutes before, no sign of her. All the sudden when I headed back she was there! Sweet. She dropped the veil. It was a daylight 8 am game time spawn.
No one else was in the zone, and I had been there for hours just killing named spawns, so I can't confirm there is a placeholder.

I am rather disappointed on the lack of information surrounding this mob. No one really understands exactly what spawns her or where to find her, there are just estimates here. I would think that the sword would have been a little more important in days long ago, and as such pulled more user input. Trouble is, alot of people browse, but don't post, so I guess I'll at least include this observation for others to utilize.

As for the Crypt.. it's a night spawn situation here, which is leading this necro to believe that she also spawns at night.

I have been in the zone for 2 days studying their behavior. Today i noticed that at 6pm game time, there were un-targetable placeholders in the spots where skellies normally spawn throughout the Crypt.

At 7pm game time all of these PH's pop out and the crypts are empty. Then, at 10pm game time the targetable versions are here, and sometimes the named that spawn here is also up, which is not even listed above.

At 5am these skellies will stop spawning and the un-targetable PH's will return once more.

This does not seem to affect the spawning of skellies outside of the Crypt as they can be up pretty much any time.

Now, as for her.. I found her up finally today about 1am game time in a static spawn at this location - -2075, -60.30, just outside of the little city area in what appeared to be an undead spawn point. She was of course utilizing the sword, but dropped the mask and a worthless weapon. This is a different location then any of the above, so I'm quite positive that she spawns somewhere, anywhere in the zone, in some type of undead PH spot. I will update this post if I encounter any new information. Best of luck, she's a long spawn :-(

I've been hunting this broad for days now, on my bard main. I looked all over the internet collating information on her spawn patterns, and seemingly none of it rang true. In the end I had her spawn, back to back and within 5 minutes of each spawn, at this location: -1465, -560. That's just north of the Crypt entrance, next to a rock and a tree.
Being a tracker helped a great deal -- doing this camp without a tracker would be truly frustrating. Anyways, I'm not sure what ended up getting her to spawn. Long story short, I ended up collecting all of the undead mobs in the zone into one big pack and then killing them off one by one, by charming and suiciding them into eachother. After they were all dead, I did the same thing to the Bertoxxulous Chosen mobs -- every single one at the entrance to the Temple zone, all killed off. It was after that that Megrima spawned at the location above.
My advice then, is kill all undead within ten minutes of eachother, then camp the Temple area and kill all of the Chosens, and keep an eye on tracking. I'm not sure whether she spawns from undead or from Chosen, but one of those tactics worked. Second spawn she dropped the sword. My pally will be a happy camper.

Also drops Veil of the Plaguecaller, item 80486.

Not sure didnt read much into it but she uses two effects. A group Harm Touch ablility EMote went Much of your life force expires in a deadly poison you take 3195 points of damage. At least thats what it looked like cause everyone in group dropped down to half there hps. Also she uses an ae Darkness looking DoT called Doombringers Plague or something close to that got cured instantly most of the time sorry i didnt get the name.

any info on how to spawn her? wanting to get the sword for my sk since hes gonna be stuck at lvl 70 for a while (im keeping up on defensives instead of getting to lvl 80 only to get my *** kicked by a LB) so any info would be much appreciated

ive heard she roams all over the zone and ive heard she spawns at night and ive tried to get her to spawn on several different occasions with no prevail so if anyone with anymore information than this would be so kind as to post it it would be much appreciated
