Choose one creature, object, or magical effect that you can see within range. You attempt crossing weaves with the target by another illusion potentially causing a violent disruption.  One non-instantaneous illusion spell of 1st level or lower on the target dispels forcing that entire spell to end. If the target is able to choose, then they must decide which illusion spell ends. Shatter Illusion has no effect if an illusion spell was not dispelled.

Besides yourself, targets inside the same area of effect as the dispelled illusion spell must make a Dexterity saving throw. Affected targets take 2d8 force damage on a failed save, or half as much damage on a successful one. If the individual parts of the illusion spell were smaller than a 5-foot-cube, then each part acts as if their area of effect was a 5-foot-cube. Shatter Illusion only triggers the saving throw and damage once on an affected target.

Attempting Shatter Illusion on your own illusion spell does not require sight to perceive it within range, and your chosen illusion spell dispels completely regardless of what level you cast Shatter Illusion.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st. Additionally, the chosen illusion spell to dispel can be equal to or less than the level of the spell slot you used to cast Shatter Illusion.
