Wondrous Item, rare (requires attunement by a Spellcaster)
This amulet has 2 charges per Long Rest. While wearing it, you can use a Magic action to expend a charge to cast an altered Thunderwave spell.
The wearer shouts loudly, and each creature in a 15-foot Cube originating from you makes a CON save. On a failed save, a creature takes 2d8 Force damage and is pushed 10 feet away from you. On a successful save, a creature takes half as much damage only. In addition, unsecured objects that are entirely within the Cube are pushed 10 feet away from you, and a thunderous boom is audible within 300 feet.
For 1 charge, you cast the 2nd-level version of the spell. You can increase the spell slot level by one for an additional charge.
Notes: Spellcaster, Damage
