Tazgaars' Annoying Sigil

You point at one creature within range and draw a sigil in the air in front of you. The sigil springs into exsistance in front of the face of that creature in a brightly glowing, undulating form. The creature must make an intelligence saving throw or be distracted by the sigil. As a result the creature suffers disadvantage on its attack rolls for that turn. After the creatures turn, this sigil disappears.

On a successful save, the sigil dissipates with no effect.

This spell has no effect on creatures that are blind or have no eyes.
