Anyone have any suggestion for how to translate Power Well and Warp Bane into Deathwatch's rules system?

Power Well is easy - I'd suggest that it grants either +5 to all Focus Power Tests, or a bonus Degree of Success on all Focus Power Tests - one of those two options should work well enough.

I can't actually remember what Warp Bane does, as my copy of Daemon Hunter is packed away and I've not looked at it in a while.
