This guy spawns in the upper parts of the theatre area en route to Alice in Wonderland Area. What sets him apart from the other jesters in the area is his costume is a bit different and he is bigger. he does see thru invis but went down easy. If ur making the run to the AiW area good idea to have a tracker check to see if this guy is up cause he will aggro you if you are running thru. Even if u make it to the chessboard the performer and his friends will glitch onto you thru walls and stuff so it would be a good idea to kill him, as he gives a fair amout of AA exp for the group when killed, and has some ok drops, it is also important to pay attention to aggro messages when u are pulling from the upper parts of the theatre, if u snag a mob from one of the terraces overlooking the stage, its possible that you will aggro everything below and make a huge train.
