[Winter] Item - Frost Grenade (Patreon)

Frost GrenadeAdventuring gear

One of the earliest inventions to come out of Xanta's Workshop, snow elves and gnomes used these contraptions to set the stage of war. They typically open with a terrifying volley of thousands of frost grenades, coating entire battlefields with snow.

As an action, you can throw this grenade at a point you can see within 30 feet of you, or launch it as ammunition from a cannon. Upon impact, the grenade explodes and coats all exposed surfaces within 20 feet of it with ice. The ice melts in 10 minutes if the environmental temperature is above freezing, or 5 minutes if it is 60 degrees Fahrenheit or higher. Until the ice melts, the surface is difficult terrain. Additionally, when the grenade explodes, each creature within 10 feet of it must make a DC 14 Constitution saving throw, taking 3d10 cold damage on a failed save or half as much damage on a success. A creature that fails this save by 10 or more also falls prone.
