Mine, stun

Mines can be set to detonate when a creature comes within up to 15 feet of it or paired with a remote detonator. As an action, you can prime and set a mine on a surface you can reach, which arms at the start of your next turn. When detonated, each creature within 15 feet of it 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.
