How about we keep the launching thing that i came up with, but instead of hurting your enemy when you hit them, you get speed 2 for 5 seconds and strength 1 for 3 seconds? Just imagine it...a silent arrow stalking it's prey in the moonlight...and then...it strikes and leaps from the shadows and fatally wounds it's prey...(I'm trying to imagine a arrow walking down the street...*shudder*)
