I'm not sure if these are bugs, but I didn't want to start a new thread. Playing as the Kahdi for the first time and have encountered some issues that I thought I should report:
1) I've received very few Psions (6, although one was killed and I'm now left with 5). I'm playing on a huge map and have a very large empire at this point: my other gated creatures number in the dozens.
2) Despite having had Earth Mana for a long time now, I've had no Earth Elementals gated in. Maybe that's intentional, but I doubt it. I have several of the other Elementals (Air, Fire, Ice, Water), as well as creatures connected to other Mana types (Pit Beasts, Flesh Golems, Aurealis, Spectres, Djinni), so this would seem to be a bug.
3) If the Kahdi complete Birthright Regained, they can end up casting both of their world spells. This doesn't seem appropriate, since the text suggests that Kahd makes an irrevocable choice to serve either Oghma or Mammon. It's also exploitative, since you can get most of the benefits of both spells. Maybe intended, but if not, then perhaps the Kahdi should be blocked from building Birthright Regained?
