Perfect spot in Galvani's house on the 2nd floor. If you've been collecting and/or saving runes you should be able to get it here.Posted by Seitzz on 28 Jan 19 at 21:12 This achievement is bugged for me (same as the Big Boy one) - I’ve done it multiple times, even got the one for staying in a vent/in possession for 3 minutes, and this hasn’t unlocked yet. With Big Boy, it eventually popped after 7 or 8 assassinations with just my sword, so I’m hoping that eventually this unlocks too after doing it enough. I’m probably at around 12 to 15 uses of it so far from doing my high chaos run.Posted by TheWyandotte on 17 Oct 22 at 17:39 Leave a comment
