As far as we know it is based on some decisions you make, dialogue that you choose within the game IE do you support mage freedom or not? Chantry or not? (if you try to make everyone happy with you, you might actually end up with a more rng divine since your answers aren't always consistent nor are your actions), and the conversations you have with the three possible divines (I think these are more used for tie breakers). You don't have to support anyone for a divine to be chosen. Leliana was going to be my divine simply because I was a very extreme anti-chantry and pro-mage character. My dalish elf never spent time with the circle or within human chantry matters. So no matter who I chose to support she was going to be my divine.
So advice? Be consistent with your actions and dialogue, and you'll probably get the divine you want.
i can't say i was anti-chantry, i kind of agreed it needs change, when talking with Cass & Lil, rest is in my last post, not anti-chantry, but i don't agree with chantry, well with my 3th char cause its human who believes he is the herald
, i did not show my anti-chantry side with previous chars neither, but can't remember awry chat i had
, but i said mages should be free often
but mostly ur right about that
maybe we are DA nerds (even if not high LVL nerds) & the type who keep an eye on almost awry thing in the game LOL
& some forget to visit Skyhold enough often, i know some dialogues will be skipped if u play to long with out talking with people & continue mane missions to with out talking with them & that mite mess things up to
with my first char i messed up few things to (not who i want as Divine part, that went as planned) i cleared all ares before getting in skyhold, all possible areas, i was lvl 15 or 16, maybe 17 to, then i W8 long time when i continued mane missions, like Wicked eyes and..., maybe even ur mission order & what lvl u do them mite effect that to, if not that ur influence lvl, cause i had it pretty high from clearing areas/Maps so that maybe saved my skin the first time
i have noticed that to get new dialogue there are 3 triggers 2 for none companions like example Cullen, mane Missions influence lvl & approval lvl, one time after i got influence lvl up i had new dialogue with Lil & some others to i think
