Sacred Defender + Stalwart Defender

[apekzz]

Hey all,
Question regarding the enhancements from both Defender trees.

DO they stack?
ie : Stalwart Defence stance and Sacred Defense stance stack? (shd i be gettin 20 PRR if i select both?)

They're mutually exclusive; you can have both, but toggle one on and it turns the other one off. The passive non-stance bonuses appear to stack, though; e.g., you can take both Stalwart Armor Mastery and Sacred Armor Mastery and the AC & MDB increases will stack. And Divine Righteousness should stack with Stalwart threat bonuses, since the former is a Sacred bonus and the latter is a Competence bonus. Plus Divine Might will stack with Power Surge. So there are some advantages to pal / ftr vs pure class of either.
