Because of STR builds dominance, I would like to suggest changes to make CHA-based Paladins more viable, with more options for the Oaths:
The principal thing with cha based is the low AB compared to other builds, so perhaps this:
Divine Sinergy (Lv.21) - While Divine Synergy is active, the paladin receives AB proportionally to (Hard CHA modifier/4)
And for the Oaths:
Inquisition
-Mark of Inquisitor: Deals and receives (CHA SOFT BONUS)% of extra damage from selected foe
Ancients
-Extra Move speed from (5 + (cha soft mod/2))% in wilderness
-Stone Skin Spell
Perseverance
-Holy Sword healing: Heals (Cha Soft Bonus)/2 per hit for the paladin and his teammates
-Extra feat at lv 26 OR Expertise at lv 6
-Healing spells with (Cha soft bonus)x5 chance of replenish in use
-Remove Extended Spell Feat
Reckoning
-Skill Focus Discipline at Lv 26
Thank you.
