Okay, I think I've decided that I'm going to try to get a custom Enlightened template approved. I'm just trying to work out how best to implement the concept I have, and I think it involves too many class levels for Paragon to be a good choice.
So, my thoughts on it so far. It isn't written up in proper style yet, this is just to give you an idea of where I'm thinking of taking it.
[sblock=Enlightened] Can be applied to any Humanoid, Monstrous Humanoid, Outsider or Undead with a Wisdom of 16 or better and an Alignment that is partly Neutral (Neutral Good, Lawful Neutral, True Neutral, Chaotic Neutral, Neutral Evil).
Type changes to Outsider if it is not already. Enlightenment is a way of transcendence, and humanity and mortality are left behind. The Enlightened one can no longer be affected by any spell that would bring him back from the dead, if he could previously. Part of Enlightenment is realizing the detachment to accept your fate and to understand that death is merely a transition.
+8 Dex, +4 Con, +4 Int, +12 Wis, +8 Cha. One who has found enlightenment exists in a permanent state of awareness and experiences utter synchronicity between body, mind and soul. He has perfect command of himself both physically and mentally.
An Enlightened person does not need to eat, drink, sleep or breathe.
+5 Insight Bonus to AC and Attack Rolls. The intense awareness of one's surroundings and one's place in them that comes with Enlightenment is a significant advantage in a combat situation.[/sblock]
I'm open to suggestions for any other abilities it should gain. I was wondering whether it should have DR and/or SR. Obviously they're not much use to me, but still... they make sense for the template, so perhaps the 'honest' thing to do would be to put them in, not sure.
Also not sure what LA it should have. As I said, I was aiming for about +5. It's probably that already, I would think, so if more abilities are added I might have to lower some of the current bonuses.
