Vicious token tip thread

So it's been a long time since I tried playing Vicious Token runs. The inner ring and Grimm's are done. But man, I forgot how horrible VT can be. Nothing like a VT run to remind you how hard DD is when you play a real challenge...
So how do you all you rainbow collectors do it? Should I go ahead and get Namtar's (haven't bothered, don't really want to give up a locker space, no monster class to unlock yet...)? Or is Namtar's not really that essential?
