Charging Angel build.
The build idea is to take advantage of the awesome Angel defensive and offensive buffs, as well as the busted Sword of Heavens Abolish Guile upgrade alongside Spirited Charge doubling all your damage on a Charge - and Mythic Charge + Boots of Stampede providing even more damage.
We use Travel Domain with Domain Zealot to be able to Swift teleport trough the battlefield to find optimal positions for charging - even every round, when so desired.
Race: Kitsune, obviously.
Stats:
Strenght: 15 + 5
Dexterity: 12
Constitution: 12
Intelligence: 16 (I like skill points, YMMV)
Wisdom: 15
Charisma: 7
Background: Acolyte.
Level Progression:
Level 1: Cleric (Erastil) Power Attack
Level 2: Cleric
Level 3: Cleric Exotic Proficiency: Fauchard
Level 4: Cleric [Animal Companion]
Level 5: Monk – Sohei Boon Companion, Spirited Charge (!)
Level 6: Monk – Sohei Indomitable Mount, [Evasion]
Level 7: Gendarme (Cockatrice) Outflank, Weapon Focus: Fauchard
Level 8: Cleric
Level 9: Gendarme Shatter Defenses, [Dazzling Display]
Level 10: Cleric
Level 11: Cleric Improved Critical: Fauchard
Level 12: Cleric
Level 13: Gendarme Vulpine Pounce (!), Cleave, [Cavalier's Charge]
Level 14: Monk – Sohei
Level 15: Monk – Sohei Metamagic: Extend
Level 16: Monk – Sohei
Level 17: Monk – Sohei Skill Focus: World/Arcana, Combat Reflexes / Imp. Initiative
Level 18: Loremaster Secret: Great Cleaving Finish (could also pick some spell.... but not sure which).
Level 19: Whatever (but preferably a pet class - Mad Dog could be good if no longer Lawfull alignment - I went with more Cleric) Cleaving Finish
Level 20: Whatever
Raise Mobility for the pets defenses via Indomitable Mount and Athletics for Charge damage proc with Boots of Stampede. Plus skillchecks.
Mythic abilities:
1 Mythic Charge (!)
2 Improved Critical Mythic / Mythic Power Attack
3 Impossible Domain: Travel (!)
4 Domain Zealot (!); Abolish Guile SoH upgrade (!)
5 Enduring Spells; Piercing Rays Halo upgrade
6 Improved Critical Mythic / Mythic Power Attack; Everlasting Flame SoH upgrade
7 Greater Enduring Spells; Solar Winds Halo upgrade
8 Mythical Beast/Last Stand/Mythic Improved Initiative/Leading Strikes/Ever Ready; I took Overwhelming Flames SoH upgrade, though I guess Speed of Light is cool also
9 Mythical Beast/Last Stand/Leading Strikes/Ever Ready; Unfailing Beacon Halo upgrade
Weapon: Fauchard. I think Finnean is the best option (but not vs undead or constructs) - as it will let you use Power Attack without worrying about accuracy loss. Mighty Blow of Good is decent.
Other notable equipment: Boots of Stampede (for another proc on Charge - alongside Mythic Charge). Hammer of the Masterpiece. Half of the Pair amulets. Shy Lily's Helmet. Clemency of Shadows Ring, Ring of Imminent Demise. Fencer's Gift gloves. Timely Assistance belt.
Animal Companion: I like leopard a lot. Thank you for the recommendation, Desiderius
Note that as a Kitsune, you need Reduce Person to ride it (possible at level 5).
The idea is to use Frightful Aspect buff (or possibly Legendary Proportions, if for some reason you don't need the Shaken effect) and then cast Reduce Person, which will let you keep most of the positive effects, but will reduce the size of your model (and your weapon too). Also comes with a slight Str debuff, but what can you do.
The smaller your companion is, the less of a nuisance on the front line. And more importantly, the closer to the enemy it will be able to activate a Charge and the less it will be bodyblocked or stuck in geometry. And his early high AC is just great. Later he doesn't need Barding, so has more feat flexibility too.
If you find the need to use Reduce Person a nuisance, go with another, preferably somewhat tanky and not too bulky, companion.
Here are the proposed feats for leopard:
1. Weapon Finesse
2. Fury's Fall
3. Dodge
4. Outflank
5. Improved Unarmed
6. Crane Style
7. Crane Wing
8. Weapon Focus
9. Dazzling Display
10. Shatter Defences
Bully to support the free Trips on with Fury's Fall. It will also need 3 Int for Ouflank and Improved Unarmed Style for Crane Style, so either add 1 point to Int ASAP or have it wear an Int tiara (Bookworm's Headband is nice for the Compulsion immunity).
A nice idea, particularly if you have more animal companions in your party, is to either have an Oracle with Nature Mystery and Friend to Animals Revelation - or dip 1 level oracle on a high Charisma character (like Ember, maybe Seelah) for that Revelation. It will greatly boost the saving throws of your pets.
Note: the pics below mostly come from earlier revisions of the build.
Edit:
6.06.2022: Updated the build to current game version. Lost some AB and a lot of critting power (without Loremaster able to select Trickster feats, greataxe spec with Mutation Warrior), but gained reach with fauchards, significant damage from Mythic Power Attack, Improved Cleaving Finish. Also moved away from horse to smaller pets, with leopard being my favorite.
