- What religions are out? IIRC, you said some unused religions will be cut, it would be nice if we could get some names. For example, the Necromancer Cult and the Sithis religion don't seem to be that important (although they do randomly pop up on rulers), but it would be a shame to seem them gone.
The list of removed religions: Arcturian, Nudri-hi, Ebonarm, Maloocian, Apologist, The Beautiful, Pact Breaker, Pact Fundamentalist, Sixth House, Reclamationist Lessons, Nirnian, Topalish, Hist Saplings, Rogue Hist, Spirits Worship, Ancestor Cult, Crimson Scars, New Hand, Anu, Void Anuiel, Miraak, Glenmorial, Nightingales
The Anuic_Religions religion group was also removed, with anuic_skaal moved to Atmoran pantheon.
- What are the changes to the Daedric cults? Are they going the be improved/overhauled (like possible reformation, holy sites, heads of religion, pilgrimages etc.) or are they replaced/changed into something else?
I doubt I can answer this question in full, but one of the big changes is that, instead of heresies, daedric cults will be popping up in provinces instead.
Not at the moment.
- Not related to the religion system, but I've seen that with the new beta patch, a modding command was added that let's you change a characters portrait gfx. Will we see this in the new patch (Lichdom changing you into a undead?)
Probably not, unless 0.1.6 is delayed significantly. General rule of thumb is that an EK patch is going to be designed around changes made in the previous CK2 patch. For example, the unit/tactic overhaul is a reaction to the new special unit system that was added in the previous CK2 patch. A lot of it is that it takes a LOT of time and testing to properly impliment something, and we generally want to get compatability patches out ASAP.
