Grenade, stun

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. Each creature within 10 feet must make a DC 14 Constitution saving throw. On a failed save, a creature is stunned until the end of their next turn.

Additionally, on a failed save, a creature is unconscious for 1 minute, until it takes damage, or until someone uses an action to shake or slap the creature awake. At the end of an affected creature's turn, it can repeat this save, ending the effect on a success.
