Took my 62 Pally with a 70 Ranger and a 59 cleric looking for a drop for the ranger's 1.5 Had group camo up and had no problems till we got to this mob. He could see right though it and has a large agro raidus so that almost as soon as we came down the well to him he attacked us. Never did have enough time for the Ranger to try Harmony on him to see if it would work, but Invis sure doesn't
Also drops Piranha Scale Sash, which is crappy for the classes listed. Only use I can think of is for a charm soloing druid. Boy, were we disappointed...
