Didn't get "Sins of your Father" achievement - HELP

[Rhowin]

I just completed a Durge playthrough and going evil as possible. It was rough as it locks you out of a lot of companion content and such.

Anyways, killed the Brain and had the option to take over the world for Bhaal, but I didnt't get the achievement. I did lose the 1v1 with Orin because she one shot me in 1 turn through the slayer form and my health bar which was fun, but the option to take over the world still said "in Bhaals name".

Help... I don't want to go through another Dark Urge playthrough again...

A bit late to the party but I think its because you lost to Orin. Happened to me as well when i lost the !v! but still tried to claim the brain in Bhaals name. I think its because Bhaal doesnt approve you anymore but still uses you to get what he wants.

so this is not an honor run ?

you need to reload and kill Orin

you have 3 rounds to kill her if you get initiative until she does her special atack which is what I think got you?

Not sure tho, I only have 1 durge play where i became bhaals chosen then defied him in the end

horrible ending

As far as I know if you dominate then brain as Durge thats the ending. Just and evil grin sitting atop the brain

not sure about the achievement..
