This magic crossbow appears as a large gilded kaleidoscope until wielded, when parts of its length unlatch and spring outwards to become the limbs of the crossbow. The lens is made of a multicolored crystal.

You gain a +1 bonus to attack and damage rolls made with this magic weapon. Additionally, when fired, the crossbow doesn’t deal piercing damage. Instead, the dominant lens of the kaleidoscope determines the damage type it deals. As a bonus action, you can try to shift lenses in order to change which lens is dominant, as shown below. In order to do so, you must succeed on a DC 15 Intelligence check. On a success, you choose which lens is dominant. Otherwise, the dominant lens is determined randomly.

Dominant Lens	Damage Type
Green	Acid
Transparent	Cold
Red	Fire
Yellow	Thunder
Blue	Lightning
Purple	Psychic

Proficiency with a Heavy Crossbow allows you to add your proficiency bonus to the attack roll for any attack you make with it.
