Icicle Bow

Weapon (any bow), rare (requires attunement)

This magical bow has six charges. When you use this weapon to make a ranged attack, you can expend one, two, or three charges to create and shoot an icicle arrow. You have a bonus to attack and damage rolls made with that piece of magic ammunition. The bonus equals the number of charges you expended to shoot the icicle arrow.

When an icicle arrow hits a creature, it melts into the creature, and the creature's speed is reduced by 10 feet times the number of charges expended to shoot the icicle arrow until the end of your next turn.

When an icicle arrow hits a noncreature, the icicle arrow shatters explosively. All creatures within 5 feet of the point the icicle arrow struck must make a Dexterity saving throw or take 2d2 cold damage.

At each dawn and whenever the bow's attuned wielder takes cold damage, the bow regains 2d2 charges.
