Fan of the Four Winds (5e Equipment)
From D&D Wiki
Weapon (battle fan), very rare (requires attunement)
This beautiful fan has an almost ceremonial appearance with a picture of a beautiful mountain scape on a very windy day, the picture itself continues to move as though the viewer was looking into a window.
You have a +1 bonus to attack and damage rolls with this magic weapon. The battle fan also deals an additional 1d6 slashing damage and has the reach property when use you wield it with two hands due to the strong gusts of winds this weapon can emit. The wielder of this fan is considered proficient with it for as long as they are attuned.
While holding this fan, you can use an action to cast the gust of wind spell (save DC 15) or the wind wall spell (save DC 15) once each from the battle fan. The fan regains use of each of these effects at dawn.
