Re: Faction/Race explained
 

This is actually incorrect. If you do a Welcomer (Kami or Karavan) you only gain fame, you do not lose any fame at all. This can easily be verified in the sys info window. Ambassador missions (Kami or Karavan in a tribal location) do function as you describe.

Other than this one correction, that's a great summary Sidusar.

Re: Faction/Race explained
 

Hmm, how does one kill faction fame, then?

Re: Faction/Race explained
 

Thanks for the proofreading!

I've done some missions for a Karavan Welcomer recently - I'm pretty sure it also said "You lost fame with the Kami". Though as said this secondary effect is smaller so maybe it's zero for missions that only give a little fame? I'll check again.

Kami and Karavan ambassadors give fame as if they were tribe welcomers, yes.

Re: Faction/Race explained
 

This is a table as a result of a research I did a lot of time ago. There are 6 tribes missed, despite I'm sure I've done missions for Slavers, but seems I didn't wrote back the results.
I already posted this table in the forum, but now I removed the fame values, that are just related to my race and not important in this context.
Names in parenthesis are the tribe names as they appear in the fame window list.

All the tribe missions were taken from the Tribe Welcomer only (even the tribes that kos me).

(*) They have no sign of a faction into camp, but 2 give positive fame with Karavan and one with Kami, also 2 of them are enemies of a tribe present in the same region, regardless of the faction.

(**) I have done one mission from some city welcomer, captain, corporal and ambassador, they all gave me the same results.

Edit: Added the missed tribes, for completeness. Thank you, sidusar

Re: Faction/Race explained
 

That's a nice extensive list :)

05 Darkening Sap Karavan, Matis Kami, Zoraļ
10 Lawless Karavan Kami, Fyros
20 Slavers Karavan Kami, Tryker

01 Ancient Dryads Kami Karavan, Matis, Sap Slaves
13 Lagoon Brothers Kami Karavan, Tryker, Cuzans
24 Woven Bridles Kami Karavan, Matis, The Arid Matis

Not all from tribe Welcomers, I admit, two of these tribes will still only let me take missions from their Scouts, but I've never seen that make a difference.
