yeah when I went through this mission on my ele it was so cake! we had all henchies on the other side and Togo took virtually no damage!
I went to go through on my ranger: assissin and rit on the other side.... togo dead before we finished the second mob on our way down.
Again: Rit Togo dead before we got the first mob (OYE!!!!)
again: assissin: made it to the last mob togo died
idea: RUN TO TOGO! = GLITCH!
So we cleared everything in the area and couldnt get togo to move his fancy pants!
disheartened cause we had a great group we dispersed and called it a night (3hrs trying to beat it).
Last night we try it again: first guy I GOT HIM HE WILL BE FINE! (assissin I think) BOOM dead before the last mob -_-
(twice this happened)
Then we come across an assassin with a staff XD!!!!
She was so confused! Anyways we talked her through it (she couldnt figure out who the heck was talking to her over local chat) and we beat it.
The trick is don't take on to much agro and try not to target anything that is not dirrectly on master togo or you will draw even more agro and get him killed! Simple as that!
The problem is being from the foriegn quarter it's easy for us - but we get lvl 15's on the other side who have no clue what to do and no party to help them till we get there! None of them are monks cause well its Cantha you dont create a new character in Cantha thats a monk!

So silly it's simple enough if the locals know what to do and that is to stay back and not attack anything unless it is dirrectly on top of Togo!
If you are an assassin for the love of all that is good: STAY BEHIND MASTER TOGO AND ONLY FIGHT THE MELEE THAT COMES ON HIM! -_- Or use a staff XD!
Poster above me: You would be surprised as to how well Master Togo can keep himself up - if your henchies are running away from agro then they aren't taking damage and Togo wont waste the heals he needs on himself to heal any of your party. Why this is I don't know but thats just the way I notice it working! I just notice it works better if they are running from him *shrugs*
