Torghast's Wings are Skoldus Hall, Fracture Chambers, Soulforges, Coldheart Interstitia, Mort'regar, and The Upper Reaches. Only two of the six Wings will be active at a time; these rotate every week.
Each Wing offers different environments, enemies, and bosses and is divided into three Layers atm. Each Layer is divided into six Floors.
Once you complete a Layer, it is unlocked and you can talk to the Wayfinder at the start of a new run to teleport directly to that Layer. The higher the Layer and Floor number, the harder the enemies get. If you already done with some Layers no need to do them again. You can get your rewards once per week from each Layer.

- layer: 180 Soul ash
- layer: 330 Soul ash
- layer: 460 Soul ash
- layer: 565 Soul ash

Also, if you re-pass the same quarter in the same week, you will get 20% of the Soul Ash, which can be useful for twinkies.
