Adventurer tier gloves. This and all my other magic items can be seen in the PDF linked at the bottom.
Gloves of Iron Grip: Anyone wearing these gloves has a grip like a vise. Not a little vise either, a big ol' cast iron blacksmith's vise. As long as you have a free hand in combat, you can grab any creature of large size or smaller. If you grab a large creature and it moves, you move with it with no penalty. Medium and small creatures cannot move while grabbed. You can also perform any act that requires a grip with no effort, such as hanging off a ledge for hours (if you really want to do something that boring.) The only thing that can break your grip against your will is unconsciousness.
Quirk: Pit Bull with a Bone. Once you have something, anything (money, equipment, mediocre sandwich, etc.), you have a lot of trouble giving it up for any reason.
