Beyonder’s Veil

Wondrous item, rare (requires attunement)

This shimmering translucent veil seems to hold shifting stars within its weave. The beyonder’s veil infuses your illusions with the essence of trans-spatial nightmare dimensions beyond the stars.

Targets have disadvantage on Intelligence (Investigation) skill checks to disbelieve an illusion spell you cast, and the target is frightened by the illusion for 1 round unless it succeeds on an additional Wisdom saving throw against your spell save DC. This works a number of times per day equal to 1 plus your spellcasting ability modifier.
