Why do the flaming fist not hunt me down for my reputation when the amnish attack me?

Please help me as I need to finish the nashkell mines with an evil party.

What do you need help on? The Amnish soldiers attack you if you have a low reputation. They flaming fist do too, but your reputation needs to be very low for them to fight you.

The flaming fist ony hunts you down when you're not in Amn, which is basically Nashkell and the surrounding areas. There, the Amnish soldiers are after you. If they seek you at all, that is.

And just because your party is evil doesn't mean your reputation has to be 1. Anything under ten is most acceptible for a badguy
