How can that be?  If a mob has a base resist of 500 to everything and this brings it to 350, mobs don't mitigate damage anymore.  The only thing I can think of is that they mitigate 0 damage based on if they have 500 to all resists... so if you bring their resist to 350 with this spell, then they essentially have -150 resistance because it is based on how much resist they started with.  So basically their base resist is a line for where they mitigate 0 damage.  I am not really sure exactly but there is one way to test it.  Find a couple of mobs and get max int and then cast this spell and just keep casting siphon life and see if it ever hits for more than the max damage.  (which I will do and report back)
