Smoke Bomb
By removing your Bomb’s explosive contents entirely, you can change it into a Smoke Bomb. This Bomb deals no damage, but creates a Sphere of smoke that is Heavily Obscured. The radius of this Sphere is twice that of the Bomb’s Explode property. The smoke lasts for 1 minute or until a strong wind (such as one created by Gust of Wind) disperses it.
