I recently acquired the red illusion from the quest “Tis But A Scratch”, but have been unable to apply it to my bretonian sword and shield. I can apply my other green illusion with no issues. When I attempt to apply it in the crafting menu, the progress bar will fill completely but will not do anything else. It will stay filled as long as I hold the button down.
Have attempted it unequipped and with another class to no avail
