I'm Genthru, Town Bomber.
Every night I have to PM the mod the name of a targeted player. This player receives a PM telling them they have a bomb, and the pm explains the rules of the bomb. They have to give it to somebody else during the buy phase, and then it comes into somebody else's possession for the Day phase. I can post a command to detonate all bombs that are in play. If somebody gives one of the bombs back to me, I can't detonate. I also can't detonate within 24 hours of the last detonation, which means I can't do it during today's day phase, I have to wait for the next one. I can only detonate twice during the game.
I have a Tracking Device listed as a passive ability that allows me to see the locations of all my bombs, but one of my Restrictions says that the device is broken and doesn't work. If my Vase of Flowing Water hadn't been ninja'd from me, I could have removed my restrictions and been able to properly track all my bombs, and I could even detonate as many times as I wanted. The 24 hour rule probably would have been removed as well. Too bad it got stolen.
Oh and my bad, I just reread the rules for the bomb, and Kary can't hold onto it. The mod will randomly choose somebody if he doesn't pick someone. That's all explained in the PMs No Lynch and Kary already received though so I dunno why you're asking me.
