I went to charge my phantasmal residue at the skill point in the Ascalonian Aqueduct skill point and ran into the following small glitch.
I happened to also have some quartz crystals in a bag at the time, and when interacting with the place of power, it would only offer me the “charging crystals” option, even though I didn’t have 25. I had to remove them from my inventory before I could see the dialogue to make my residue “weird.”
Ideally, you would see both, I think.
