Not to be a jerk, but gwenmaster is 7.2, gwenperion is one of the 7.1.6 bosses
I don't know if I have a favorite, although it was insanely fun to try and beat Scytalis when 8.1 first came out and the whole game bugged out so that you couldn't see any of the traps she placed. It might sound as if I'm sarcastic, but I'm not. I think that was a really funny new element to the fight. It could easily have been a node. "Deal 25% more damage to Scytalis when she's Wounded, but you can't see the traps".
No confirmation bias hapening here I see...
We need an option for necropolis grandmaster now. 😉
ALL of y'all are on some drugs, all boss fights are neither fun nor interesting, they are just a "pain point" to siphon resources and force players to spend units. its not enough with the 20 different aggravating nodes they put on the paths for them and on much of all of the content, but, also, you have to do pain point bosses too in conjunction with nodes... its like having a bike with one pedal, half of a handle bar, no seat, flat tires, and weak brakes, to ride up a mountain with... but, go ahead, tell me i'm wrong, and tell me that y'all love these bosses so much that y'all routinely go back and play them for fun, They're just that enjoyable!!! The heck with all that...
