Arelith

Right now, it feels almost lackluster (at least in theory in my head) compared to how much everything else is now.

It was super cool at first, but I feel like it was like a poke of your toe into a lake to test the waters with what could be done.

I'd recommend:
-100% ASF
-Raise the HD to d8 (If it wasn't already?)
-IF POSSIBLE allow for the Arelith specific epic spells (-ward, -scry, enchanting, ect.) to work with only Greater Focus, and level 24, to try to simulate favoured souls getting all the way to ninth level spells in PnP (and make it take piety like a cleric rather than spell components?)
-Is it possible to give the choice of taking feats at non-feat levels?
Like allowing someone at level 5 upon levelup to take a feat they would not be able to otherwise.
If so, at level 10 give the PC Resist Energy and let them choose what to be resistant against, or just give it automatically based on alignment
-And then, possibly expand upon the Resist Energy and maybe give DR of some kind.

Just my thoughts. Does this make it too much like warlock? I feel like the loss of bard song is a huuuuuuuge thing.

OH ALSO. Is the Raise Dead ability still infinite for Favoured Soul? That seemed a bit. Much. Especially when Cleric Healers only get it 3x a rest.

If the Favoured Soul is supposed to be a Cleric that just casts divine spells without preparation like a Sorcerer/bard, then I agree with the -100% ASF since divine magic can be cast in armor. I also agree with raising HP since Clerics are meatier than bards. The Energy Resistance and DR though 'does' sound like pushing to match the Warlock changes.

I refuse to comment on the current Raise Dead of Favoured Soul

The whole epic spells and greater spell focus idea though seems like your thoughts are in the right direction, but you missed the target. No offense meant

Since bards miss out on 7-9th level spells it does seem like the Favoured Soul is missing out on something the class should have. Then again this would depend on if my original assumption about this class was accurate. If Favoured Soul is more than just a spontaneous casting Cleric, then someone please point it out so I know what I need to be talking about lol.

This is where I got the DR and energy resistance idea from.
