Does bonus wave gain bonus armor?

Hello, my question seems kinda stupid but I wanted to know if the bonus wave was getting bonus armor. And if they do, I wanted to know how it's working. And my second question is: What is taken at the first place, Armor reduction from knus or armor penetration? It would help me on some of my run :3. Thanx for your reply :D

Hey Saroe, yes, the armor of bonus round waves is increasing like in the regular game. Every wave that is spawned has +1 more armor than the previous wave. And it's first knusperhexe (her aura simply substracts eaten creeps from creeps armor), then the cactus' reduction melts the remaining armor.

Thanx for the information, I think it should be interesting
