You're talking about Presto's hat. Yeah, I noticed that too.
That's kind of what I'm already trying to do. It's already got +2 Force, and is a +1 composite longbow with two +1 abilities, for a total of +5. The Illuminating aspect of it is no problem for me to afford, but the Power Shot and 2d6 is what's bugging me. I'm not terribly worried about the Power Shot feat being part of the bow, but that extra damage would come in very handy. I'm considering just adding a +1 frost, flaming, and/or shock to it because they'll be 1d6 force as well thanks to the +2 ability, but still.
