I'm playing mystery of Westgate as a druid and didn't turn into a vampire after I accepted that option thanks

What? I don't understand what you are trying to communicate.

OK, so I think I know what the OP is about. In MoW, if you choose to become a vampire, you do not get the feats, any of them, not mark of the vampire or any of the powers feats. The don't show up in the Feats/History section of the character sheet like the game says they should, so, no-power vampire except in-dialog powers usage, which really sucks.

The feat should work though, there is discussions about how to use it outside of MoW so it is not broken like some other feats....

The feat didn't appear in my character sheet under feats/history in 2 different playthroughs, so yes, it is broken somehow. I just want to know how to fix this problem so I can continue MoW, as a vampire with powers intact.

Do you have mods installed?

Especially check the override folders in your userfolder (Documents\Neverwinter Nights 2) and in your gamefolder. A rogue feats.2da might be the culprit.

Could you provide a savegame made before the conversation which should give the feats?
(Had hoped I can play up to that point but wont be able to do so)

Would like to test it ;)

OK, so I deleted all of the feat.2da or feat.2da files in my override directory, and went through the dialogue to become a vampire again, and this time it worked. Mark of the vampire and the 4 powers feats all appeared in m feats/history section like they were supposed to. Oh, I also verified and repaired the installation after removing the 2da files since the game crashed without them. The whole reason I wanted to get this working, aside from MoW, is the MotB Vampirism mod which I am trying to port the vampire character into by exporting him and then importing him back in the start of MotB. So far, the vampire stuff is not showing up in the MotB mod, rhe Vampire class is not there to select, but after I level up my character, there are feats ind the history tab with names like Cleric, Paladin, Monk, and I think fighter, maybe? So that is the next step in my journey if you can help with that mod too, that would be appreciated. Thanks for all the help in fixing the vampire issue in MoW.

Not sure if this helps?
