Boss Fight – Cogwork Dancers
Let’s break it down.
Silk Telegraph Dash Attack
They will telegraph their dashes with a strand of silk showing the direction.
Moving in Unison Strategy
They move in unison and in every direction. There is split second after they telegraph the direction.
Damage Window Timing
This is basically your opening for some damage. Then jump over/ dash the attack direction.
Criss-Cross Arena Attack Pattern
The second major attack is this criss-cross apple sauce attack all over the arena.
Staying in Safe Gaps
Stay in the gaps. This pattern will change, watch for the gaps and stay in it.
First Stagger – Shorter Attack Windows
After the first stagger, they will go back in their chambers and come back out. Now, the window before they start moving will be much shorter.
Middle Meeting and Twirl Move
They will also have this move where they meet in the middle.
They will do a twirl and then shoot back out. Keep dodging and going in for a hit and keep your distance.
Second Stagger – Unsynchronized Movement
After the second stagger, they will go back in their chambers again. Now they won’t be moving in unison anymore.
Defeating the First Dancer
Their movements will be staggered. The basic strategy is the same, though. Keep dishing damage till you get one.
Final Phase Solo Combat
The other will retreat into its chamber and come back out. Much simpler now so whittle it down.
After Cogwork Dancers Victory

Once they are down you will be greeted with a large ornate elevator.
