@lycantrop - Izki's Noxious Gust kills any characters in front of the current target of Petrify. You want to time it so that Petrify is on your tank when Noxious Gust goes off.
There seems to be an issue with having multiple items of the same type. I had 2 round shields (because I had to make a second one for the quest) and both were equipped, selling one sold both.
Wisdom definitely has something to do with tower placement. I tested on level 1 by placing 2 towers next to each other so they both hit the creeps and then playing again where 1 tower soloed everythng and the other was off in the corner. The result was wisdom badge on the first attempt, but nothing on the second. I did a third attempt where both towers were in range of a large amount of track, but the first tower still soloed everything. Wisdom badge awarded.
TLDR: Place your towers where they can cover the maximum amount of track to get the wisdom badge.
I think I'd enjoy it a bit more if skill points cost more the more points you have in a skill, rather than the absolute "each point costs more than the last no matter where you put it"
Ok, lvl 5 seems to be impossible, mainly because the enemies level up just as fast as you do. Also, the more I play, the more buggy it gets. I had a soldier explode like a frag and kill half my team.
