Tempest Tide (Patreon)

Trident, rare (requires attunement)

You gain a +2 bonus to attack and damage rolls made with this magic weapon. You can use a bonus action to hold this magic trident above your head and speak the command word. When you do a storm cloud appears above you in the shape of a cylinder that is 10 feet tall with a 60-foot radius, and for up to 10 minutes freezing rain starts to fall.

The area is heavily obscured, and exposed flames in the area are doused. The ground in the area is covered in water, making it Difficult Terrain. When a creature enters the area for the first time on a turn or starts its turn there, it must make a DC15 Dexterity saving throw.

On a failed save, it falls prone.

While holding the Trident you are unaffected by its effects and a creature hit by this weapon takes an extra 1d6 cold damage. The trident has 3 charges and regains all expended charges daily at dawn.
