Defensive knowledge skills were nerfed ages ago to be 1% per 5.
I miss the days of taking 0 damage from all physical sources. . .

If it was 1% Physical and Magical DR per 5 faith while invoking, that's maybe fine. Still kinda pushed I think. Lowered damage + Healing is a ruthless combination, and faith already adds to your ability to resist interference. I also don't really think the trait adds much to the class overall. . .
Devotion is really cracked and I still think that'd be a bit pushed for an already excellent class.

I always imagined the no prayer tool and no devotion thing was an intended feature. As a high faith character who wants to use devotion for power, I actually enjoy it not being around. Faith is already a really good stat.

Personally I think it'd just be best to keep things in the same spirit and just make you have a 2.5x faith% less chance for invocations to be broken, so at 40 faith you don't need to spend your 7 talent points to make your invocations unbreakable. 1 skill point for 7 talent points is a pretty good deal in my opinion. Its only a terrible skill because you literally can't get it to 100%.
