Kaylon mentions taking Bear's Fortitude, so that's probably here the extra 10 is coming from.
Sword and Shield Style is a pretty big Reflex boost if you keep up with enhancing your shield's quality. My Paladin had minimum Dexterity and maximum Intellect and Resolve and Reflex and Will were dead even. In the case of Orlans, it helps that you can crank Perception so high to make up for the missing Dexterity. Remember that S&S itself adds 6 to the shield's deflection, and that plus the quality modifier stacks with the shield's base deflection to transfer over to Reflex. Even with a small shield like the Outworn Buckler, that can easily be 8 (shield) + 8 (exceptional) + 6 (S&S) = 22 Reflex, not counting the extra bump from the Herald quality.
Yep, added bear's.
As for reflex, assuming 18/16/3/20/3/16 build:
20 base + 33 level + 27 faith and conv + 27(buckler w herald, up to 30 with exceptional big shield) + 10 fox + 10 defiant resolve + 10 item = 157-160. + whatever you get from food/rest but if you're using might/con/res resting bonus then nothing from rest probably. Still almost enough.
And just to finish the picture: will
20 base + 33 level + 27 faith and conv + 10(15) item + 10 defiant resolve = 100-105 + whatever you can get from food/rest. Plus there's a paladin passive for +15 vs a lot of will based afflictions. Weakest save but still quite good.
All in all, looks pretty solid.
