We need a fresh start. Colson lost sight of what we need to be a long time ago, and I don’t think his protege is the one to give us anything but more of the same. I think a council is the way to go in the long run, but for now, I think Tamrin Credence has the decisiveness to take us in a bold, more meaningful new direction.
I was thinking about this just today, and am kind of leaning towards the Arcane Trickster with a Fey Sorcerer for the arcane class.
Bards are, of course, always awesome. While I haven't looked closely at the Sandman Archetype, I could really see Realistic Likeness as being a great way to get close enough to use their spell stealing ability. They're all about deception, which Realistic Likeness would add a lot too.
I would also recommend looking at an Inquisitor with the Infiltrator archetype. Ranged Inquisitors can be devastating, and their added abilities all would go well with realistic likeness.
An almost 7 foot tall, very solidly built man with a slightly angelic look to him, and a copper tinge to both his hair and skin walks in, finishes whatever is in his mug, burps, and says "Hi, I'm Thaddeus Meade. You may recognize me from such Knowlege Geography lectures as "Galt with the Wind" and "So I Married a Cheliax Murderer." Has the mean guy already insulted us and told us our mission, or did I get here too early again?"
I would suggest skill focus; Knowlege Planes. Few things are more embarrassing that hitting a Devil with cold iron. Plus, it would allow you to get a Familiar with your next feat. A Thrush would make a wonderful backup singer for you, and be ridiculously appropriate for a follower of Shelyn. And of course, the eventual possibility of a Cassian Angel or Silvanshee Agathion sidekick is pretty awesome as well.
Is he only interested in maximizing his own pleasure, or everyones? If the latter, what about an Evangelist Cleric of Cayden Cailean with the Revelry subdomain. Kind of like Bluto in Animal House, adventuring both for the adreneline rush and to fund his massive Toga parties between adventures.
Good news: after spending a lot of gold and effort to atone, you still get to be a Paladin. Even better news: You are now a Goblin! Now you can see first hand how wrong it is to mindlessly judge things on appearance alone, and can hopefully teach others that lesson.
p.s. Now go plant some wheat, you slacker!
