I did my (naked INT - 7) and your (naked INT - 7) for the sheet above. I was subtracting 7 because I assumed that was the INT value for the numbers Pharcyde posted.

Mine is 195 ((lvl - 1) * 5), yours is 245. You can see from the chart that your Drain Life does an average of 16 more damage per cast than mine, for example (if both our characters are naked).
