Drizzle

As a bonus action, you can expend 1 charge, summoning a rainstorms in a 20 foot radius, centered on a point you can see within 60 ft. The area becomes heavily obscured and difficult terrain, however you remain unaffected. Any creature, other than yourself, that moves within the area, must make a DC 13 Dexterity saving throw or fall prone. The rainstorm remains for 1 minute or until you dismiss it.
