Lock of Lullabies - 5e

Magical trap (Simple trap, levels 1-4, setback)

Description. This is a trapped lock enchanted with the sleep spell. It can be locking a door, a chest, or a window.

Trigger. Unlocking the lock without its key will trigger the trap.

Effect. Once the lock is unlocked without the key—like with thieves’ tools—or it’s broken, sleep is cast from it at 2nd level.

Countermeasures. The lock has been enchanted with a 3rd level glyph of warding, which casts sleep when activated. Finding the glyph on the lock requires a successful DC 14 Wisdom (Perception) check.

Casting detect magic reveals that the lock exudes a magical aura of abjuration, and casting identify reveals the nature of the glyph cast on it. Alternatively, a creature that is aware of the glyph may make a DC 14 Intelligence (Arcana) check to learn its nature.

The only way not to trigger the glyph is by opening the lock with the correct key, which is enchanted to dispel the glyph. Alternatively, casting dispel magic will dispel the glyph.
