Skylance 3 the library:
This mission basically involves running around and matching up the clues with the items you see on the outside. When you get all 8 right in a row you kill boss and leave. Everytime you use the switch more mobs spawn on the outter ring. A good FD class can make this mission go fast. It took my group about 30 minutes to figure it out and win the mission.
Here is the solution for the puzzle. The emotes come in random order and every time you get one wrong you have to start over and a mob spawns in the center. I didn't write down the exact emotes for each point, but this should be close enough.
1: Remove Necromantic Tisue
2: Trans Injector
3: Ethereal goo
4: Call Spirits
5: Manipulator
6: Dispensor
7: Gaze'o'rama
8: Spirit Disteller
