Glass Wand of Leng

The wand weighs 4 lbs and is roughly 18 inches long. When you tap the wand, it emits a single, loud note which can be heard up to 20 feet away and does not stop sounding until you choose to silence it.
The tip of this twisted clear glass wand is razor-sharp. It can be wielded as a magic dagger that grants a +1 bonus to attack and damage rolls made with it. 
This wand has 5 charges. It regains 1d4 charges daily at dawn. While holding it, you can use an action to expend charges to cast one of the following spells (save DC 17): arcane lock (2 charges), disguise self (1 charge), and tongues (3 charges)
