Trifrost Trident

Weapon (trident), rare (requires attunement)

This metal trident is covered in sharp icicles. It has 3 charges and regains all expended charges daily at dawn. It deals an extra 1d6 cold damage to any target it hits.

Once per turn when you hit or miss with a ranged attack using the trident, you can choose to expend 1 of its charges to cause a dazzling flash of ice and light to erupt from the trident. Each hostile creature within 10 feet of the target must make a DC 15 Constitution saving throw; the target of the attack has disadvantage on the save. On a failed save, a creature takes 1d10 cold damage and 1d10 radiant damage and is blinded until the start of your next turn. On a successful save, a creature takes half as much damage and isn't blinded. In addition, friendly creatures within the effect's area gain resistance to cold damage for the next minute. The trident then crystalizes into solid ice, shatters, and reappears in a flash of light in your open hand or at your feet (your choice).

Worlds beyond number can be seen through the icy fractals left behind, each vision a fraction diverged from the last.
