You might have come across a glowing purple rock or a wall with a little circular insignia over it in Shatterscarp, Galawain’s Tusks, or the Garden. You’ll need Soul Pods or Yatzli’s help to get rid of them.
These are Illusions, and the only way to get rid of them is by using Yatzli’s Dispel Illusion ability in your Radial Menu (E/LB/L1).
You unlock Yatzli at the end of the quest “A Path to the Garden” in Thirdborn, the main city in Shatterscarp.
Illusions tend not to block you from any rare or Unique loot, and so it’s safe to leave Yatzli at camp if you like. Typically, there’s just a treasure chest underneath with some upgrade materials and money, but there are a few exceptions:
- Trickster’s Boots (Clothes) in Shatterscarp
- Helwalker’s Vestments (Armor) in Galawain’s Tusks
- Wayfinder (Spear) in the Garden
As of Update 1.4, you can also use Soul Pods (Poison Grenades) to get rid of these purple obstructions just like you can use other grenades to eliminate other obstacles. Other sources of Poison don’t work.
