Prestige Plus agent of the grave Modded build recommendations?

[Kobold]

so the prestige plus mod https://www.nexusmods.com/pathfinderwrathoftherighteous/mods/552
adds the agent of the grave prestige class and at level 5 you have the option of learning all necromancy spells for a lich build, becoming a vampire, or becoming a ghast.

I am very interested in doing a claws/natural weapons build centered around being a ghast but am unsure of how to build my character around that and still meet the requirements for agent of the grave (5 in arcana and religion and be able to cast 3rd level arcane or divine spells)

Claws with spell casting is tricky as as far as I know, only shifter and elemental rampager gives you permanent claws, do you know what the 5 levels of ghast give you? Shifter doesn't give you spell progression so won't multi into ghast, where elemental rampager will but it is a class around wildshape aka changing into an animal. But if you can live with ignoring that feature, the class gives you spells and claws that hit their final upgrade at 15, so pairs well with the 5 levels of ghast.

If your ghast can give you unlimited claws then we have a lot more options, like sorc 6/7 into 5 ghast into the rest in dragon disciple. This would give you claws but limited uses of them per day so that is why I am hoping ghast has them.

Then the question of mythic path, I normally wouldn't suggest legend off the start but a set up like this would benefit huge from it. Then you could easily take the best for your claws and really boost your melee capabilities.

Ghast does come with with perm claws as well as a aoe effect that makes enemies around you make a fort save or become sickened i believe. rn i was going into shadow shaman since thats one of the few classes that give you the requirements the quickest as well as giving sneak attack not sure what else i should multiclass into tho thinking either monk or barbarian
