While I love the Razmiran/False Priest archetype for sorcerers, something that always bugged me is the fact that everyone seems to use scrolls and wands as the source of divine spells for False Channel. It's convenient and they're easy to acquire, but it completely kills the flavor; you're not going to convince anyone that you've got divine powers when every spell you cast is preceded by fishing around in your haversack for the right magic item and telling everyone to look away and cover their ears.
Rather than play a comically inept phony priest, I went looking for alternatives to scrolls. Turns out, it was another sorcerer archetype that had the answer: spell tattoos don't require storage, are silent to activate, and the activation method (touching the tattoo) can easily be disguised by dramatic posing as you revel in your divine might. Sadly, the archetypes themselves won't stack, but the crafting feat is easily acquired and the Razmiran Priest's UMD bonus means you can easily make use of divine scrolls to meet the crafting requirements.
With the thematics solved, I'm now wondering what sort of sorcerer build would work best with this theme. Tattoos are somewhat slot-limited (you can fit 11 on a humanoid), so I'd need to pick the most useful/impressive divine spells to have 'on me' at all times. Bloodline is fairly unrestricted, though I'm leaning towards Rakshasa (making it even harder to distinguish my arcane casting from divine) or Arcane (everyone loves a familiar, and with the transfer tattoo spell it could serve as storage for additional tattoos). Further, once False Channel is acquired at level 9, there's not much stopping me from multiclassing out or going for a prestige class. Tattooed Mystic and the Razmiran Priest PRC are the obvious contenders, while Pathfinder Savant gives great bonuses towards magic item use.
So, any advice? How do I make this build into the best pretender priest it can be?
