When I did this on my pally, to my memory - it was really effective. I only put 40 points into Int, having a total of ~110 Strength / ~105 Dex / 50 Int / 55 Vit

This was at L55
However my gear was : L55 Sword - 216 EE / L55 Plate - 41 Str & 8% Quick Draw / L50 Heal - 53 Dex / L50 Heal - 140 EE
I did about 80% Success Rate, so with a ~130 EE weapon you might be at about 60-70% Success (I'm guessing)
Mind you, I was hc and I had to run many times - but I think If I did stay on most of those runs, I could of killed and improved my success rate. So you might have an advantage there being softcore and might not have to run as much
I guess you will just have to trial and error, hope this helps somewhat though
Good luck slashing,
