Im a little crazy, but this is what Im currently playing in WotR.
Oracle (Lore) 1
Paladin of Arshea 7
Ranger (TangleBriar DemonSlayer) 1
This build is a CHR for everything build. Its probably pretty cheesy but its a lot of fun.
Human: Charming, Reactionary
Paladin 1 - Fey Foundling, Noble Scion of War (CHR to init)
Oracle at 3rd - Sidestep Secret (CHR for Dex to AC, Ref saves), Extra Revelation: Lore Keeper, Knowledge Skills become CHR based
Ranger: favored Enemy Evil Outsiders +2
Greater Mercy, +1d6 to LoH if target isnt afflicted with the Greater Mercy focus. Seeing as how this will be you, its a must. getting an extra die, means at least 3 more HP and maybe up to 8!
Slayer's Knack: This is some cheese. Taking a level of Ranger, and at higher level, you get this for Evil Outsiders and double your crit range. Its insane. Keen for free more or less. In WotR its a nobraniner. As is getting Bane: Evil Outsider on your sword ASAP!
I just took Celestial Obedience: Arshea, for a +4 on Diplomacy rolls if target could be attracted to you, that stacks with Charming for a total of +5. At 9th level, I've dumped everything into CHR, have a Headband of Alluring Charisma, so my CHR is at 24 (+7). My Diplomacy is +21 (or +26 if possible attraction). Not bad.
Smite Evil is really nice, +7 to Hit and AC. really nice.
For Mythic, I may have broken/misused it? At least in HeroLab, when you take Mythic Paragon it treats you as +2 to your tier in ALL regards, including HP. So taking Guradian with Mythic Paragon got me 15HP. I also took Extra Mythic Feat and went Dual Path: Marshal.
That was probably less than optimal. Absorb Blow and Decisive Strike as Call/Order.
In my build taking the Armor feat for light armor is actually worth it. It removes the Max Dex from the armor, so i can keep pulling max AC from it. its within one point difference between +1 Full Plate and +1 Chain Shirt, plus I'll have 30 ft move.
The Paladin+Fey Foundling makes you nearly unkillable, in and of itself (at least in Society play). Oradin all CHR build adds to that, my saves are all +15 or over, +9 to Init, LoH 10/day for 3D6 (4D6 greater mercy). Its pretty nice.
The BIG downside? Im so Evil Outsider focused, its tough killing your average human cultist!!! Maybe not tough, but man, it takes a long time! I only have a 16 Str, and no Power Attack or anything to increase damage. But against EO, I can dish it out!
Tiefling is very nice for the racial level bonus, you could have some crazy LoH!
Most of the other players have taken Mythic Power Attack/Deadly Aim. Theres a power that removes your range increment penalty, our Zen Archer is taking that.
Hope that helps! Its a fun AP. Good luck and remember: A.B.D.E. Always Be Detecting Evil! ALWAYS!
