(I'm a n00b here, so if I should have done a search, or posted to a different forum, or whatever, feel free to indicate as much.)
I want to create a power that has a wide variety of effects, and roughly 25-30% of the time it does something rather wildly different than intended. Ideally I'd like the "accident" effect to be varied enough to be amusing, and more towards confusing/awkward than outright harmful. The player I'm working with was suggesting that for example they might accidentally turn somebody into the Jolly Green Giant. I'd like to aim for something a bit less comical (I want this character to fit into a somewhat grittier environment than that would imply), but equivalently weird and unpredictable. My first thought was something like:
Nd6 of Luck
Multipower (side effects of blasts), with e.g. entangle, rka, flash, maybe one or two others.
Energy Blast Nd6, linked to Multipower, variable special effects
Then I would have something (I'm unclear on how to make this work correctly, much less legally) depend on a Luck roll level 1, and choose the number of luck dice to correspond to the target chance of failure (6 or 7 dice, I suppose).
Then I need something like a side-effect that triggers on luck roll failure.
So, that's kind of close, but it still feels wonky, and limits the character to energy blast type attacks. I'd like a more chaotic feel, and I'd also like a cleaner model. At the very least, I need help figuring out how to arrange the above components.
Oh, and this is in the context of a standard power-level champions genre.
Help?
Thanks, -John
