Eldritch Sigil

You inscribe a glowing sigil of chaotic eldritch energy on a surface or object within range. The sigil covers a 5-foot square and emits a faint, ominous light. Choose one of the following effects when you cast the spell. The effect lasts until the spell ends or the sigil is dispelled.

Eldritch Barrier. The sigil creates an invisible barrier of force around the inscribed area. Any creature that touches or crosses the barrier must make a Wisdom saving throw. On a failed save, the creature takes 2d10 force damage and is pushed back 10 feet. On a successful save, the creature takes half as much damage and isn’t pushed back.

Void Ward. The sigil emits an aura that disrupts magical energies. Any spell of 3rd level or lower cast within 30 feet of the sigil requires a successful Intelligence saving throw. On a failed save, the spell is countered and has no effect. Spells cast by you or your allies are unaffected.

Eldritch Alarm. The sigil acts as an alarm. When a creature other than you or your allies comes within 30 feet of the sigil, it emits a loud, disturbing sound that can be heard up to 300 feet away. The sound awakens sleeping creatures in the area and continues for 1 minute unless you dismiss it.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can choose one additional effect for each slot level above 2nd. You can activate each effect once per casting.
