MrCheezIt was working on this a while ago. I'm implementing his changes for the dead deities; he never got the monster deity changes typed up.

DEAD DEITIES    LISTED DOMAINS                NEW DOMAINS
Amaunator:      Knowledge, Sun                Law, Sun
Bhaal:          Death, Evil                   Death, Evil
Ibrandul:       Earth, Protection, Strength   Cavern, Earth
Moander:        Death, Trickery               Death, Trickery
Myrkul:         Death, Trickery               Death, Trickery

Surtr is indeed the correct spelling; the Faiths of Faerun forum has been updated to reflect this.

I'd still keep knowledge domain for amaunator as a placeholder for planning.

Also instead of Sea caves.. you could use simply Sea. which is talktable strref # 31429 used in place of any deities with OCEAN domain or WATERY DEATH domain.

Neither Helm or the Red Knight get Knowledge, despite having the Planning domain. This is because there is not a lack of suitable NWN domains for those two deities. As there is not a lack of suitable domains for Amaunator, I do not see any reason to add additional domains only tangentially related to domains that he has in canon.

I dislike domain names that have unnecessary punctuation in them. They look clumsy and unpolished.

"Sea Caves" is a substitute for the Ocean domain.

I guess the point is moot when it comes to amaunator, he's afloat on the astral plane , only a remnant left, considered dead by most and lost by everyone else.

As for substitution yeah it's a great idea, i'm sure theres quite a few other gems that would make good substitutions for other unimplemented canon domains. I do agree about the unneccesary punctuation making it look "ugly" but it is just a pick from a bad choice for some of my other domain ideas.

since someone was asking about this in IRC...

has anything been done about the poor abandoned monster deities? Are they updated in game and just not on the forum listings? or are they not updated at all?

Forum listings should be consistent with the way they're handled in-game.

Alright, as of v841, the new domains suggested above have been added for the monstrous deities.

Forum listings updated.

Forum listings should be consistent with the way domains are handled in v841.
