Vanquishing Snake Dance - active quests?

I'm about to vanquish 3 of the 4 remaining areas to achieve Legendary Vanquisher, Snake Dance > Dreadnaught's Drift > Lornar's Pass all in one go, wich makes up for a colossal number of mobs and spent time.

So I'm doing everything I can to shave some of it off. The wiki reports that some active quests can lower the number of mobs in the 1st area by 80+, but for the life of me I can't find anywhere wich quests are those and where I can get them. Wouldn't somebody be able to help me out? Both wiki's and google failed me on this.

Wiki areas> check what quests that involves the area>get them>???????>Win

I think it's just luck with spawns and popups in Snake Dance. Anyway, you shouldn't worry about Snake Dance, it's easily the easiest of the three.

There is no quest that I know of really. Good luck with your vanquish ;-) hope everything goes alright

Derp, go read the OP.

Anyway, I got started on the VQ after posting and it was easy. Took me about 3 hours to clear all 3 areas, not nearly as bad as I thought it'd be considering I once took 4 hours to do Talus Chute. Now all that's left for Legendary Vanquisher is Grenth's Footprint, will get on it tonight.

Thanks to both of you.
