We already have Performance 5. Combined with Excellencies and Charms, we probably can out-debate a lot of people. Granted, we need to eventually be able to outdebate everyone, which is a hell of a task, and there is something to be said about new Charms...
Especially seeing as Performance is Supernal, we can get those regardless of their Essence requirements. It is tempting to be an absolutely peerless orator, to be honest.
Hm. It seems down Performance path there are literally charms to harm demons in an area around him. That'd be very much Ignatius tbh.
OTOH, we probably need to beeline TWT, especially given that we chose Defiance. Which means higher War can be of use.
On the third hand, we will probably need to diplomance Navy representative soon...but that's not necessarily Performance.
On fourth hand, not relevant to this vote, we probably really need Dodge and Athletics to survive assassins and stuff.
And Resistance 5 to not be poisoned.
[X] The Pilgrim's Path. A series of minor shrines and monasteries, traditionally visited by those who wear masks to preserve their anonymity. Walking the paths as one of the crowds has always filled you with a sense of community and peace, which will allow you to return to your duties appropriately refreshed.
[X] War. Witnessing first hand how a planetary peacekeeping operation is conducted, along with the insight offered by Canoness Galina, has been educational.
We need at least some more levels of War; 2 is very much not enough in 40K, I fear.
