This amulet is fashioned from a natural crystal that shimmers brilliantly in moonlight. While you are wearing it, you gain the following benefits:

• You can use the amulet as a spellcasting focus for your warlock spells.
• You can try to cast a cantrip that you don’t know. The cantrip must be on the warlock spell list, and you must make a DC 10 Intelligence (Arcana) check. If the check succeeds, you cast the spell. If the check fails, so does the spell, and the action used to cast the spell is wasted. In either case, you can’t use this property again until you finish a short or long rest.
• You have advantage on saving throws against being charmed.
