The Great Expanse

This spell envelops a select group of targets in a dull, blocky monochrome vision, stripping away the vibrancy of colors and reducing their perception to shades of gray and splotchy patches of shapes. As a result, targets are unable to distinguish between creatures and inanimate objects, making it difficult to identify threats, allies, or obstacles, even affecting senses like tremorsense, truesight, blindsight, etc.
