Dark Cloud/Steve

Steve is a slingshot (Xiao's weapon) that you may pick up in Wise Owl Forest, but it's rare enough that you may play an entire game without getting it. As a weapon, Steve isn't that great and it's only upgrade, Super Steve is nothing spectacular either, but it has the ability to talk and it makes comments on the monsters you fight with it. Most of what Steve says is blather, but if you pay attention you can find a few pieces of useful info.

Steve starts talking when you target and enemy and says 10 different things for each one. These are in a cycle and to restart from the beginning just open the Item screen (you don't have to do anything there) and close it again.
