Des's Imperceivable Object

You touch an object no larger than 5ft in any direction, that isn't being carried or worn by another creature and its form begins to shift in such a way that it becomes difficult to perceive, even in plain sight.

For the duration, any creature other than you must make a perception check against your spell DC to perceive it, or have a passive perception that is higher than your spell DC. The object can still be perceived by touch, or any other non-visual sense where applicable. It is also susceptible to true sight, and any form of detect magic if magical.
