This is all just my opinion on what I learned and took away from fighting there two bosses, I'm hoping that this can help people who may not fully understand how they work and if there are points that I messed up on and may not have stated correctly or clearly enough feel free to inform me in the comments so I can fix it to not only help me, but others as well.
###My Thoughts
Having Wei Wei will make all runs go a lot smoother due to her Skill 2 giving a massive defensive buff, may not be required BUT highly recommended. I ran my Stage 10 Akhenaten and Damocles with the Defense Formation to apply the defense buff to my squishier characters and an attack buff to my DPS characters.
