The black bonecharm on the top of Addemire can't be obtained without powers. Since it's on top of the roof. I tried to get on the roof via the window but to no success. If I make any progress I will update you guys.
However I did find a way to get the Blade Verbena without powers. Basically you need to carry a few bodies onto the small roof leading up to the window. Just climb the pipe and try your best to jump on it. Then stack the bodies on the end of the pipe (the one across the side of the roof) because the pipe goes a little higher near that end. Stand on top of the bodies and jump to the wood part near the window. It doesn't matter whether the bodies are alive or not. Jumping on the NPC probably won't kill them but I haven't really tested that out.
I'll try to get the video out again, but last time it didn't work too well cause I messed up the rendering. So I just wanted to state that I found a way to get that souvenir (Blade Verbena) with no powers, and that the black bonecharm on top of addemire cannot be obtained without powers. At least not yet.
Bonecharm on addermire very much impossible atm y, we've tried all sorta shit - can't even grab on to the surface so even if you'd have abit more height coming from the window, wouldn't help sadly.
It's an obvious oversight by the devs.
NOPE. I did it. I got the Blade Verbena on No Powers! I have a video of it on PS4! Will upload tonight! If you don't believe me I can PM you my PSN with the trophy list and you can see. Got the souvenirs trophy moments before getting the no powers trophy.
"However I did find a way to get the Blade Verbena without powers." Ye he obviously wasnt talking about that when you literally wrote it in your post...........
Dude, the fucking souvenirs don't even belong in AC D: like, no need to stress about it. Damn.
