Yep, I turned off all the shits from 1st and 2nd fight and the 3rd was a push over. Finally complete! Now I need to unlock Uber lab. Time to run more maps!
I also tweaked my build. Instead of Mon'Tregul's Grasp, I'm trying a Midnight Barbain. Zombies are squishier, DPS is less, no AoE explosion corpses, but I get 12 zombies now instead of 6, so I can handle larger groups. So far so good. I'm sure on harder maps I'll have to switch back to Grasp, but so far I like the larger army I have :-)
