I've been playing through KH 2 final mix recently and was starting to wonder about the "Draw" ability. If allies have it equipped, does it make treasure attract towards them? Or does it further boost Sora's treasure attraction ability?

I always assumed it worked for the character who had it equipped making it a shitty ability (Donald don't need that health orb). But that can't be right. Also, I can't seem to find the answer anywhere.

I believe you are correct as it is on a per character basis not just increasing Sora's Draw capabilities
