Nice battle.
The Queen was able to stay up front FOREVER.
I think because your enemy (because of fog of war) went with more ranged attacks... but YOU planned for that (with shielded monsters). Once their tanks (melee) were gone it was them attempting to kill your backline, but they couldn't... leaving the Queen to destroy over and over. Love it!
I've been getting a few of these in my rewards lately. I need to move my account about and get leveled up better. #timeforupkeep

Yeah I know that Nectar Queen is a Melee monster so could be used as a Tank for sure. But I tried firt time like this and found useful because I was used to place Flesh Golem or LA as a tank always whenever I had to play with Earth Splinter.
