Becoming an Unholy Assassin has no ending consequences for any character.

  • For any non-Dark Urge character - becoming an Unholy Assassin is just an inconsequential roleplay thingy that provides access to the exclusive Bhaalist equipment, more lore from Sarevok and a quicker access to Orin.
  • For a Chosen Dark Urge character - it provides all of the above and is also a requirement if one wishes to gain Sarevok as an ally against the Absolute.
