In fact, the only way to get the item is to use extremely metagamey option prior and some shenanigans to prevent the event from firing in the first place.
I'm not judging you but you wouldn't be frustrated if you didn't know about the reward. I don't know if you're experienced on playing games like this but when we saw dark urge we knew it would be an origin that would sacrifice a lot of things (maybe even companions) so we didn't choose it. You can't get everything in this game unless you spoil most of the things to yourself and that's not fun at all in my opinion. I'd recommend you try to enjoy the story and the way your origin interacts with it.
You can wait before fufilling your Dark Urge until the sidequests are done. Part of being a serial killer is choosing the right time
Thanks for the spoiler, I guess?
