Let her take you to her chamber.
Then, you can kill her before she calls for help (You can spam Hold Person on her freely until it sticks and then enter TB mode and beat her up if you need more than 1 round)
You can kill her, then if she called for help, leave the area before someone rings the bell (You can loot her key from her corpse and then enter her basement) which will reset the "Temporarily Hostile" effect on everyone else.
You can allow her to put a character to sleep (Has to be a non-elf), then have your party raid her basement while she's down there in dialogue with your character.
I think Hold Person is pretty reliable if you have Shadowheart or spellcaster with that one in the mix, that's my go to now. I've had it happen too many times where I forgot I was an Elf. Instead of initiating convo to drink the potion, just ping her with hold person until it lands to crit her for the dirt nap. Silence draws aggro immediately when it fails, but if she saves vs CC spell usually she just fires off the warning line so you can try a second time for the honour hehe. If she somehow gets off an alarm anyway with 1 HP, or you get caught up like that, you can break for the door to her inner chambers. Then dip to camp to regroup from there before someone hits a drum or Roah joins in the fray, since she has better stuff later on. If trying for Minthara KO, I like doing her then Glut, cause if you get stuck in the weeds and have to summon Lump you can draw aggro towards Ragzlin to make sure all the Ogres die with the INT boost. If you just want to post up in the rafters and take out all the drums while the gobbos get dropped by team Lump that's a pretty good show. Ideally though you just gut Gut immediately with Hold Person or Command Halt which is also pretty solid. There are two barrels of smoke powder in the area behind Ragzlin which can even the odds. like if you just want to blow her up with no fuss and then jet for the door. I think they're a little lighter than the firewine downstairs for a monty haul kaboom there. I feel like barrels are free game if they're just sitting right there across the way. Seems believable enough, like pretty much the same deal as magical arrows in the chest upstairs. You can also kite the goblins to one side or the other by using a darkness arrow if you want to funnel them around for dagger clouds and such, but I think it's easier to do those antics after the Minthara/Gut/Downstairs. If you're stuck with no spellslots trying not to wake Minthara from her beauty rest, the cost is 100 GP on a Shadowheart respec at Withers. I like Thunderheart Shadowheart, comes back from camp with shatter to wreck. Lae'zel with a barrel in her backpack can come pretty clutch. Guess it depends on who all is around. On a second out, sometimes it's just expedient to smoke em if you got em hehe
