Spawned for me right where the red dot is in the map, second set of 3 goos working back from the tunnel entrance. By the way, I don't have a picture of him, but he is easy to spot amongst the other goos, he is MUCH larger than the regular ones and is a green color (acid right?) whereas the others are a dull brown. So no need to run around conning them to see if he's up, if he is, you'll spot him right away. He took a while for me to spawn, but dropped the aug on first kill.
Using the Angram Coldheart spawn point as a reference, he has spawned for me in the first tunnel clockwise and the second tunnel clockwise. I don't know if it's always the same, but he spawned in the second set of goos in that first tunnel and way back in the second tunnel. Some of the regular goos can see through invis. My group consisted of two 85 mages (with ~1700 - 2000 aa's) and one 85 shaman (~1100 aa) each with J5 mercs (two wiz and one healer). Killed it twice and he killed group once (bad pull).
Ok so after many many hrs searching goo's for this guy i finally found him he was at Location -1939, -1135, -390. For those of you that use maps from raspers its right around where zendrilla the dread is. camped the area for 4 hrs before he spawned and got my aug on first kill =) (ill try to get an image uploaded to show where he spawned)
Went back here tonight to farm aug for friends and he spawned 3 times in 2 hrs 2 things ive noticed are he spawned from the same goo each time which was the front goo of the 2nd set of 3 and his spawn rate was increased (that or im really lucky lately) GL
Good question Relife. I'd like to know where Acidic Goo's new /loc is as well. He seems MIA since the patch that changed up all the named spawn points. Nobody seems to know where it spawns now.
since the patch has anyone seen this mob pop in s different spot other then the PG zoneline? .....popped him twice there prior to the patch but yet to see it pop there since.
