Creatures relying on eyesight and with a Wisdom score of 11 or less ignore the target as if it were not there—unless directly attacked or addressed by the target. Creatures relying on eyesight and with a Wisdom score of 12 or higher can make a Wisdom saving throw to pierce the illusion and see the target of the spell. Blindsight and tremorsense work normally.
At higher levels: If you cast this spell using a spell slot of 2nd level or higher, you can either target one additional creature or increase the duration of the spell by 1 hour for each slot level above 1st.
