Ironfall

The Mystic can create an illusion that alters the appearance of an entire room, building, or small outdoor area (up to a 60-foot cube). The illusion can make the environment appear as something completely different—transforming a mechanical factory into a lavish mansion, or disguising a battlefield as a peaceful forest. While the illusion is active, creatures within the area must make an Investigation check against the Mystic’s spell save DC to see through the false appearance. The illusion affects all senses, including sight, sound, and smell, making it highly convincing. Physical interactions with illusory objects (like walking into a fake wall) reveal their intangible nature, but the overall illusion remains intact unless dispelled or disrupted.
