Staff of Swarming Insects-2/2

Insect Cloud: While holding the staff, you can
use an action and expend 1 charge to cause a
swarm of harmless flying insects to spread out
in a 30-foot radius from you. The insects
remain for 10 minutes, making the area heavily
obscured for creatures other than you. The
swarm moves with you, remaining centered on
you. A wind of at least 10 miles per hour
disperses the swarm and ends the effect.
