Traits

A mythical trait controlled more often than not by a leech's developing psychic abilities or natural magnetism.   

It's never hard to pinpoint a leech with floating objects, as they will have something levitating close to their body!  These objects vary from leech to leech and may be something the leech values, a man made accessory, or even things like appendages and eyeballs. 
Whether or not the object can be pulled from the leech's grasp is entirely up to the leech, but it's a better idea to let them be, just in case there are other more dangerous psychic abilities that the creature is hiding.

Note: This allows for one object per upgrade, but multiple upgrades can be made for more objects.
Floating appendages will require an extra limb upgrade.
Floating eyes are non-functional.
