Ever tried ganking someone in booty bay but your target has too much hp for you to kill before you have to jump in the water and book it? Well ive found personaly that if you have a "Gnomish Mind Control Cap" and use it on a enemy player right after you jumped off the docks, your target will *most of the time* go aggresive to the gaurds and will get beat to death, causeing durability. Its really quiet fun
What you do is first target your enemy, Have cap equiped, jump into air *make sure you are falling to the water* and while falling use it on enemy.
it does have a chance to fail like all engineering things and youll become your enemys slave, then in that case nothing happens but losing a 30 min cooldown
Hope this helps
