I know everyone wants to keep it to fantasy items only here. But it's my thread and I say balderdash to that!
Poké Ball
Ranged (0), Unique Perk: Capture! (+40), Cancel: Humans and Owned Pokémon (-20),No Damage (-20)
The poké ball can capture Pokémon as well as store a single item per ball. They do not work on humans or pokémon that have been captured by another poke ball. Now if the poké ball works on ghosts, slime monsters, elves, demons, or any other non human creatures is up to your Game Master.
We all know it is easier to capture something when it is weakened and OVA already reflects that so I didn't do more with that. The poké ball itself does no damage, but if the target is captured, then they are effectively out of the fight.The target can try to roll to break free of the capture as if it were resisting paralysis. If some one attacks the ball it can interrupt the capture like interrupting the paralysis perk. The mechanics behind this is the same as a paralysis perk taken twice that paralysis on contact, except if you fail your escape roll you are trapped in a poké ball until some one lets you out.
