Thanks for the wonderful replies and the good discussion everyone.
It seems that the HN is the first choice of everyone here, so I'll camp that. I considered it before, but since I generally had no trouble getting 100 TP in 60 seconds, I was using slower, higher damage weapons. I'm still intrigued by the Kidney Dagger, so I might buy that just to try it out too.
I will look into the Chicken Knife too, but I was thinking of pulling with blind bolts for a slight increase in survivablility against the perma-flee mobs. I used sleep bolts to pull the wyverns in Riverine site A01, and that worked out well, but that would be a problem for xp chains.
