Next I'm trying Bogroot Growths. I considered this one to be a simple and easy dungeon in NM so it seemed a good one to do next in my "warm up" series.
Yeah right.
I'm a warrior and I'm using a standard aoe axe build. I brought along the sabway trio and my usual selection of henchies (Lina, Cynn, Zho and Aiden). Not fun. I struggled thru the first level and I do mean STRUGGLED! We limped onto the 2nd level with full 60% DP and I used a powerstone. The plants at the 2nd level spawn point finished us off quickly.
So, round 2. I read wiki and see that it suggests using a lot of SH Eles. That makes sense. Plants hate fire, right? Plants that can't move outta SH must really HATE fire. I got a plan.

Back at camp, I grab Zhed, Sousuke and Vekk, arm them to the teeth with fire nukes and pick up Lina, Mhenlo, Aiden and Zho. We head back out.
Geez, this round is worst than the first go. We die upon entering the dungeon. We can't even kill the first mob and I don't feel like wasting another powerstone. I had 5 hexes on me and I'm sure the rest of my team did as well (judging by the 8 pink bars that were rapidly turning black)
Round 3: Dump Zhed. Grab Dunkoro and load him up with anti-hex stuff. Attempt to buy flame thrower and a few grenades from a passing Asuran arms dealer and head back out. Result: a bit better. Made it past the first mob. Died trying to kill the Patriarch holding the boss key and the mobs surrounding him.
So, here I am. I know this isn't a hard dungeon. I've blasted thru it with no problems many times on NM. What am I doing wrong? Any advice on builds?
Please don't suggest something that will require real humans. Remember i'm stuck with 4 of the henchies for now. I know this dungeon is possible with henchies.
Of course 20 powerstones in my backpack will work as well, but i'm not quite that desperate yet.
