Vanishing Veil

Description:
You conjure a swirling haze of refracted light that bends reality itself, creating a field of invisibility around you. All creatures of your choice within a 15-foot radius become invisible until the spell ends or until they leave the field.

This shared illusion is delicate — if any creature within the radius makes an attack, casts a spell, or otherwise directly harms another, the entire veil collapses instantly, ending the invisibility effect for all creatures affected. Once a character leaves the field they cannot benefit it again.
