Possible PB run victory method?

Not sure if this helps, but a Corsair's Hypnotize also de-aggros monsters.
Are there any other skills that de-aggro monsters/bosses?

Disorder makes the monster lose aggro completely.

Hypnotize does the same thing, and is ranged.

I don't think it would work, though.

Reading a hypnotize thread reminded me, however i specifically left out hypnotize for 3 reasons.

1) No corsair maxes it or is high enough to do so.
2) It's useless compared to disorder unless maxed. (see point 1)
3) Corsairs deal a lot of damage. Having them for such a purpose would be a waste, especially since a corsair can't survive having the aggro towards them as well as a shadower. (nor could they take aggro in the first place)
