The line "take the boots" makes no sense.
I have already taken them.
- Go to mykoid village, agree to kill the duergar
- Talk to duergar and agree to get the boots
- Make an inspection check on the poisoned gnome in the mykoid village and take the boots
- Kill the duergar and find the antidote
- I can give her the antidote ( the whole village becomes hostile then ) or take the boots ( makes no sense, I already have them )
If anything I should be able to give her the boots back to cure her without making the village go hostile.
