Sigmascape V1.0

Strategy

Shoot the train and don’t stand in the AOEs. There’s a stack marker that’s a column rather than the usual roundy bit. Sometimes spotlights will chase you for a bit and then leave a puddle (like the fire in the Ala Mhigo scorpion fight), try to place the puddle on any ghosts in the arena to disperse them.

If you touch a floaty ghost, you and the ghost will get teleported into a sleeper car (to get out, kill the ghost and exit via the aetherial clicky), so try not to.

There are a few adds to clean up, and then you get to jump up on top of the train and kill a Doom Chimney! Yay!

After the Doom Chimney, you hop back down and everyone gets a debuff that kills you if it stacks too high (like the suffocating toad bubbles in Rabanastre); face plant into a floaty ghost to be teleported into a sleeper car and clear the debuff.

Then you go back to shooting the train and avoiding AOEs and dispersing ghosties with puddles of light.
