How would you handle the old fastball special?
I've got a high-strength fighter in our group who wants to throw our halfling barbarian into the middle of combat, and I'm not sure how to handle this. I'm considering treating it as a charge attack that lets the barbarian bypass difficult terrain and interposing characters, but I feel like it needs a little more than that. I was also considering treating the target as flat-footed (after all, I'd sure be surprised as hell if a foaming-mouthed halfling was flying at my face), increasing the damage dealt on a successful attack, or knocking the target prone.
My group isn't rules-savvy or munchkiny, they're just trying to have fun, and I want to let this work without giving them too much (I get the impression they're going to do this a lot...). Any ideas I haven't thought of yet?
