1d10
You can move instantaniously from "point A" to "point B"
You + 50 pounds/4 levels may teleport. You have a margin of error of 1d100-4/level. If it lands within this range you have no mishaps when teleporting. If it does not you could teleport to a place you didn't expect (nearly always at least similar such as warehouse "C" instead of warehouse "A".)
You can teleport 4+Positive CoP mod. times in quick succession.
