Smoke Grenade

This black canister has gray marks tracing holes that will produce large quantities of smoke in a short period of time.

As an action, you can throw the grenade to a point on the ground you can see within 60 feet of you. Where the grenade lands, a 20-foot-radius sphere of smoke will appear. The smoke spreads around corners, and its area is heavily obscured. It lasts for one minute, or until a wind of moderate or greater speed (at least 10 miles per hour) disperses it.
