This mob spawns at 630.20, 90.44, -146.06 and will ROAM down the center pathway past the other mobs there including see invis Belikos so be careful. He will eventually path back to his spawn point so take him there.
Spawns adds (time based) that hit for ~4,000.
This mob spawns at 507.03, -197.75, -124.93 and is at a STATIC location. It also can be found at 586, 34, -147.
After much guess work based on the posts listed here and two weeks looking for this guy I want to give out two of the EXACT spawn points for this mob. Hopefully this will keep future hunters from killing their hopes and time by having to guess where Creeping Mold spawns. The PH mobs as was stated earlier will always be a Large Beetle so look for these as place holders. The first spawn point is at 630.20, 90.44, -146.06 and will ROAM down the center pathway past the other mobs there including see invis Belikos so be careful. He will eventually path back to his spawn point so take him there. The second spawn point is at 507.03, -197.75, -124.93 and is at a STATIC location. Both of these spawn points are visually within eyesight distance from each other so there’s no need to run all over the place looking for them. When Creeping Mold spawns I don’t think I got any adds to step in to assist him when I killed him. He will however spawn his own adds at a rate of one every 20 seconds so kill him as quickly as you can then take care of the adds that he’s spawned. It took me about three kills of him to get my Golden Ore. Good luck guys !
Additional info, killing this mob for AC aug, me (90 SK) and my T5 cleric merc.
HP = approx 1 million (just a touch over) Adds spawn every 20 seconds after aggro. Took me 143 seconds to kill him and got 6 adds. Don't know if there's an upper limit to how many. Adds have about 200K HPS each. The beetles and insects inthe area do not assist; you can safely pull the named thorugh/past them. Except for one 'an odd looking insect' which will assist if there's one in range.
Killed 4 times so far, type 7 cloak every time, + a couple clays.
Well yeah that spot isn't the only place he spawns, just one of them; other posts below point out other spots.
I suspect that the Creeping Mold can spawn from any of the 'a large beetle' spawn points in the area, as have seen him in the same spots and/or wandering hte same paths that they do - but I'm not certain.
I killed Creeping Mold four times today to get the two augments I wanted. Mob spawns at LOC +640, +45, between the zone wall and a stone pillar. Placeholder was always "a large beetle". As indicated below, the mob roams in a zigzag pattern between spawn point and the nearby Genari statue. I sat on the spawn point and killed nothing but the placeholder/named. No other mobs are within agro radius.
post patch where they consoldated / moved some named / ph-ers, I found one up at approx location pos 500 x neg 50 x neg 145. It was pathing north west of that location to south east. the location is center of its path. I did not kill it so do not know what can spawn there when named not up. This path takes the Creeping Mold from approx between farm 7 and farm 2, down through First Avatar of Saunk ( from the instance) and ends up a little north of genari 3 spot.
Eh more info please. what class/stats are you/tank? adds die quick? only four adds? and at which point in the fight? are they rootable/snarable? i am assuming fight didnt last long enough for additional info to be collected. just wondering. but thanks for the warning!
