Instrument of Ice

Made of ice taken from the highest peaks of the mountains and enchanted with the powers of the elemental plane of water, this instrument has been imbued with magic to never melt.
While playing this instrument, all allies within 60 feet deal an extra 3d8 cold damage.
Additionally, any allies within 30 feet of you while you are playing also gain resistance to fire damage.
You must use your bonus action each turn to continue playing, and you cannot attack or you lose concentration.
The instrument has 5 charges and regains 1d4+1 each day at twilight.
You can expend 1 charge to create an icy gale that deals 1d6 cold damage to any enemies within 30 feet of you and the instrument at the beginning of their turn or when they enter the space. Furthermore, the gale causes visibility to fall, giving an attack disadvantage to any enemies in the area.
