I'd have to say that the Khlysty aren't really worthy of going for a strong bless.

Considering they're MR 11, boosting that with an S bless seems a waste of time, since most spells will still affect them. Even with a twist fate they're going to drop like flies.

Also the blood bless is pretty weak. Strength is good, but they have a decent chance of killing non HI already with a morningstar. And the curse (+ small horrormark) chance is pretty useless.

However, the F9 is always good when you can mass something. That should add the extra damage, and ensure they hit stuff with the morningstars.

So I'd say F9 if you're going for a bless for the Khlysty, but that's not even where Bogarus shines.
