2-level Enchantment
With this spell, you blow softly through your material component. All undead creatures within range must make a Wisdom saving throw to avoid falling into a trance.
If a target has a CR of 1 or lower and it fails its save, it is stunned for the duration of the spell or until it is physically disturbed. If the target has a CR of 1 or lower and succeeds on its save, it has disadvantage on its next attack roll or saving throw.
If the target has CR higher than 1 and fails its save, it has disadvantage on its next attack roll or saving throw. If the target has CR higher than 1 and succeeds on its save, it is unaffected.
When you cast this spell using a spell slot of 3rd level or higher, it affects undead 1 CR higher for each slot level above 2nd.
