An arm and a leg or a heart? Well this is an easy choice then. Give them your heart! Cause why give them two things when you can only give them one? :lolface:
www.moogle.com I've heard they have pretty good prices :lolface: Not to mention they have a large variety, Light realm, Dark Realm, Heck, Even twilight Realm Keyblades. :lolface: xDDD
There's one Moogle Synthesis Shop in Traverse Town that makes a pretty badass one. All you need are the right ingredients.
Screw that, just steal one. Just go to this big castle and fight the hooded aingsty teenager with issues. Do that and you can steal his nice keyblade.
