Grenade, Incendiary (Devastating)

Grenades can be set to detonate on impact or with a timer that causes them to explode on initiative count 20 (losing all initiative ties). As an action, you can prime and throw a grenade at a point you can see within 30 feet + your Strength modifier x 5. The grenade explodes, setting the ground in a 10-foot radius ablaze for 1 minute. The fire ignites any flammable objects in the area that aren't being worn or carried.

When a creature enters the fire or starts its turn there, it creature must make a DC 24 Dexterity saving throw. The creature takes 12d8 fire damage on a failed save, or half as much damage on a successful one.
