If we need a narrative justification to explain a stat spread which is higher than the PC can achieve via point buy, we can just say that it was the Absolute who granted her those extra Attribute bonuses with the crazy high Charisma etc.
Perhaps if she ever strayed from the path of the Chosen, she knows she'd take a hit on all her Attributes in divine retribution lol. Basically the Absolute granted her a +2 ability score increase to everything, and a +5 in CHA so she'd be persuasive enough to carry the gospel of the Absolute effectively across the Realms.
The narrative conceit is that she went from something like...
STR: 13 DEX: 14 CON: 13 INT: 8 WIS: 16 CHA: 10
Which is more like an achievable Stat spread, that the player might recognize from their own Character creation process. But she's got the Absolute's boost to that all around, so...
This explains how she become such a potentate. If she didn't keep the Absolute happy she'd get knocked off her hight perch down to a more normal Stat spread. But staying True, she's basically a murder machine!
