Wow that is really impressive! 3x as far as I got during my attempts :-D
Really nice strategy you had with that Shadow :-)
Nevermind, came up with an even better strat. 1716 Seconds, could have gone basically indefinitely except I did 2 major mistakes, one is my fault, one is slightly less my fault :/

My mistake was discarding my Gib, my unexpected mistake that ended my run is that I equipped a second Unrelenting Force, then removed it later. This apparently removes your force stacks even though one is still equipped. Fair enough it makes sense, but it was devastating :/
But how? 70,000 sec in Hard and 30,000 in Normal.
My longest seconds in normal is 1600 in my 10 hours game play. How to achieve that seconds.
