Arcanists Circlet

The Arcanists Circlet is an item that was recovered by The Phoenix Knights from Adair of Storia's demiplane. The item was then sent to Savic Lofthaven II as a token of gratitude from Sanctis Lofthaven II. 
It is an ornate silver circlet that seems to conjure three swirling motes of arcane energy above the wearer
When attuned to the circlet, it allows the user to cast the spell "Magic Missile" as if it were a know/prepared spell. Additionally, as a bonus action the user may fire one of the arcane motes at a creature within 120ft. Each mote deals force damage equal to 1/2 the users level rounded down. Once all motes are used, they replenish after 1 minute.
