I do feel like a lot of people in this thread have either forgotten or never noticed that you do not need to help her attack the grove to recruit her. You *only* have to not kill her. (Knockout still counts as kill because game.) The tieflings still die off screen, sure, but not by your hand, and the grove survives. Which also means you can have Minthara alongside Karlach and Wyll. ....I still agree you should be able to spare and recruit her while saving the tieflings though. Because if you kill enough of the goblins that should save the tieflings by virtue of their not being a goblin army left to attack them, regardless of whether or not you deal with the leaders.
people haven't forogtten the meta gamey exploit and no one would do thought a wiki page or guide telling them, we just ARE TALKING ABOUT SOMETHING ELSE ENTIRELY and can people stop 'um actually'ing with this game-y exploit as a solution to this problem in every thread it comes up in as it has ZERO to do with this conversation and isn't a solution.
I am not talking about an exploit. You are SUPPOSED to be able to recurit Minthara without helping her attack the Grove. It is entirely intended. She even has dialogue with both Karlach and Wyll, because it is completely intended to be able to have them in the party together.
The only thing that was an exploit, is screwing with Halsin's dialogue/quest and sequence breaking to get him and Minthara. That's the only combination of characters that isn't supposed to happen.
If you proceed to the mountain/act 2 without killing the leaders, it completes the "help the tieflings quest" with "you didn't help the tieflings and they died in an ambush" and Minthara moves on to be recruitable in Act 2. Neither Karlach nor Wyll leaves the party, because you didn't do anything to make them see you as an enemy. You just didn't do a particular side quest. You stayed out of it, and the story moves forwards with the results of you staying out of it.
