=/=? At level 8, he'd be a 8th level caster, -2 CL for not worshiping The Dark God would make him a 6th level caster. So that's possibly a loss of 2d, 2 minutes, 2 rounds, 2 hours, etc
Edit: Which raises the question(third time now 
) which Yuan-ti Deity does this settng use? Standard D&D one?
Edit 2: Already have a planned Red Lotus member in the party?
=/= is "does not equal". He'd be an 8th-level caster with a CL of 6. Yes, -2d, -2 levels for duration, etc... but still access to the correct level of spells and the right number of spell slots.
The only homebrew deity is the Dark God. Any other deities (racial deities, etc.) are standard.
And maybe not... I was just suggesting a possible way to connect a Yuan-Ti and a Firre Eladrin.
Also liking the idea of a Human Cleric of the Dark Lord. Would be alot more simple than the Yuan-ti, so not sure. Need a bit more information and such first.
Seems one of the gaps is a Divine Caster.
Edit: Also, wouldn't a large snake creature be uhhh.....rather obvious...? 
Human Cleric would certainly be easier from a backstory perspective. But again, I don't want to stifle your creativity... so we can make a YT work if that's what you want to play.
And as for obviousness, that's what Deceivingly Innocent Form or Alternate Form are for.
It seems that sponsorship isn't as great as I thought. (As I understand it) It is only temporary and you pretty much lose "everything," the only benefit really being that if your selected domains are shared with The Dark God, you get to cast those spells at full strength/caster level. So there's another monkey wrench. It just seems that perhaps a Yuan-Ti Abomination Cleric isn't really going to work out for this campaign. I'd still like to make it work, I'm just not really sure if it'll be that great. Starting off he'd be pretty much a grappler, and we already have(I believe) two meleers.
So thinking more "realistically," might go ahead with a Human Cleric of The Dark God.
Need a bit more in-put though before any final decisions are made, if the Yuan-Ti Cleric can be made to work, awesome. If not, no big deal.
The way "sponsorship" works is that you essentially change your deity to the Dark God. You don't lose anything except access to domains which aren't on the DG's list. But if you want to go back to worshipping your original deity, you have to atone.
Aye, most of them RP. The thing is really starting off he'd be a grappler pretty much. It wouldn't be until 8th that'd he'd beable to cast divine spells. And from what I see, a divine caster is a current gap in the party.
While I'd very much like to see if we can make the Yuan-Ti Abomination Cleric work, I think for time-saving-sake, I'm going to go ahead and work on a Human Cleric of the Dark Lord.
While it's established that PBPs are slow and we may never get out of 6th level, what's the highest possible level for this campaign?
Highest possible level is 20th. This is going to be a pretty brutal game, so expect a lot of experience. Should help offset the slowness of the medium.
