If you have to deal with Pandora herself, go for the sorrows. They're basically 5ss upgrades to her damage, and although they don't do much on their own the damage builds up if you fail a WP duel near several of them.
Austringers are always useful, especially since their long range keeps them outside of Pandora's death bubble.
I find the scribe is pretty much an always take, as if needs be he has 4 wounds, and so can be used twice for Devil's deal and thus immediately makes his points back.
But yeah, focus on the schemes and strategies against Pandora, doubly so since you're Lucius.
