Equip the Rift Device in your quick use items (e.g. where you placed your wands usually).

Select the Rift Device by clicking it once, then 'target' *whateveryoulike* by clicking on the target.

You will still need to hit *whateveryoulike* once to kill it. I think the Rift Device takes any creature down to 1 HP.
