Haha, we had a trampoline when I was younger, sadly my grandmother sold it.. D=

There really aren't any great limits to the abilities. xD; especially seeing as I've based it loosely off of an old rp I had with friends a year back or so. However it generally goes that Vampires have an average of 2-3 abilities if they're in the council (sometimes more), and 1 ability or less if they're not in the council.. Werewolves really don't have abilities on average.

Basically the abilities are up to your imagination as long as you don't god-mod with them. There should be a weakness somewhere of course, even if it's a mental block the character has against using the powers to a certain extent.
