Hello guys
I discovered how to fight Mandokir without his raptor.
You need to be a Rogue (Maybe NE or mage ?)
You must cast VANISH at the same time that Mandokir dismount + Re-pull mando.
It's realy easy after 2/3 try.
Here is a video of the exploit
On Youtube.
On Vimeo. (up in 25~min)
Sorry for my English i'm French.
Have Fun
