Let Kagha tell us that thanks to our cruel decision to help her with the tieflings, the druids were able to maintain their independence and avoid problems with the goblins, organize a celebraty party with the druids for us that will leave good feelings.
If you help her to maintain independence of druids ... they are right now locked inside the groove under the roof of thorns. O_o
She specificly tells you:
No one enters, no one leaves, the sanctuary.It should be self-explanatory. :-/
Only way to avoid ritual of thorns, and therefore allow druids to parcipiate at your party is ...
- either expose Kagha as Shadow druid ... wich could lead to either her death, or her redemption (trying right now in curent play) but i dare to presume that if we will save both druids, and tieflings ... they should be both present on that party aswell.
- simply join Tieflings, and kill Kagha for Zevlor ... wich will lead to death for all druids ... so, kinda dead party if you ask me
- steal idol of Silvanus ... not sure here, since i didnt try this way yet
Ofc. there could be others that i dont know about so far.
Let Minthara see that MC can be a true friend she can trust, who won't stick a knife in her back for Lolth, the Absolute, or anyone else.
Simply ... no. -_-
Once again you are trying to change characters. :-/
There is no words like "thrust" or "friend" in Mintharas vocabulary ... you need to understand that she grown in society, where such things are weakness and litteraly anyone is more than willing to use it against you ... if there even can be some kinde of friendship between her and our character, it should be build during gameplay for quite some time, and it still should be carefull and unsure from her side.
She simply either desires you, or you are obsacle for her ... i dunno what you dont like on it, for me its just fine to at least sometimes see in story some unhealthy, or inperfect relationships ...
Let the fake paladins of Tyr tell us that the infernal legions are grateful to us, and perhaps offer cooperation in the future. Now there is no reason to kill Karlach, it leaves a bad feeling that we are getting nothing morally for it.
Show the paladin leader as a difficult person who will tell about his difficult fate which made him serve evil, so that we feel sorry for him no less than Karlach.
As someone else allready told here, this is classic "one tells the truth, one lies" quest ...
You can create some believes, you can asume ... but you are not suppose to "know".
Also, tell us that the infernal legions are grateful ... are you serious here?
Do you really think that someone who give so much effort and possibly resources to convince us that he is a paladin should reveal that he tricked us?
Dont you see here a little contradiction between trying to trick someone and confess that you tricked him?
