Okay, chief!
So,
1 - No teleporting into living matter, at least not yet (Manton limit gets to me even outside of Worm-verse, dang)
2 - After a dozen or so of successive teleportations guy gets really dizzy, bleeds from the pores and needs some time to regain his bearings and stop his teeth from escaping out of the head.
3 - Only SOMETIMES fast enough to aimdodge an already-fired bullet.
Plus something else of which I am yet to think.
