Nystul's Golden Revelation

With this spell, the wizard can reveal hidden, concealed, or invisible creatures within the conical area. The concealed creature is surrounded with an aura of golden light, shining out in a 1-foot diameter about the creature, making it easily seen. The wizard can make a full 360-degree sweep-search of the area in one round. The spell might reveal a thief hiding in shadows, a barbarian concealed in natural terrain, or a creature hiding behind an obstacle. The spell creates a glow around an invisible, out-of-phase, ethereal, duo-dimensional, or astral being in the area of effect, as well as a creature using a cloak of elvenkind, robe of blending, ring of chameleon power and so on.

No saving throw is allowed against the golden revelation, although successful magic resistance protects a creature from being outlined by the spell.

The material component is a box wrapped with waxed parchment, containing a glowworm.
