In Bhaal's Name.
A Truly great Finale for the dark urge, where you stab the emperor in the back at the last second, take control of the netherbrain AND thrall your companions who fought bravely to break their chains only to be enslaved again this time by a greater evil. All of it,for your actual Father, Bhall - The God of Murder.
Overall the Journey as the dark urge was even greater, piecing together what you were and then discovering your powers if you choose to accept them. The Butler being basically Bhall messanger and how
YOU caused the entire game plot to start before being betrayed by your sister. It was you who suggested the plan and it was you who put the crown on the Elder brain.
In the end, the ending it's just your plan coming to fruition and basically the villain winning and I really appreciate the option as it was great.
And of course embracing your dark powers does give you access to an amazing transformation...
THE SLAYER
This form is great as it basically acts as a druid transformation meaning on your mage you have a close range fighter with over 100 hp and if it dies you go back to your normal form with all your remaining hp, thus becoming a lot more survivable, which you will need in the fight against your sister since that is a 1v1 and she HITS like a truck.
overall this path connected the whole story in such a way that you'd think the game was made just for it, but there are a lot of other stories without it but I honestly believe that this is one of the best stories you can choose from at first. And if you do choose to resist it, it creates a very fun dynamic and morality between your character.
Some scenes were absolutely brutal and many children were slaughtered, about 7 thousand vampires souls were killed and a couple of genocides here and there. It is truly the /Chaotic Evil/ option and it was a very fun experience. Although now I'm headed to make a good character cause I almost started to feel bad at the end.
