I don't know if this is common knowledge but it isn't explicitly explained here and it is relevant to anyone doing a NG+? playthrough. I did Varre's quest before 1.06 and my first priority in starting my first NG+ last week was to head straight to Altus plateau right after I killed Godrick to get the giant crusher because the chest was bugged and empty for the entirety of my first playthrough. I also went to writheblood ruins for a third great-stars and the red NPC invasion sigil allowed me to invade and kill Magnus. I wasn't playing offline and I hadn't spoken to Varre outside the rose church before invading Magnus. I didn't interact with any grace checkpoints at Altus plateau while I was there.
The interesting bit is I spoke to Varre at rose church earlier and he gave me festering finger or whatever. I switched to offline play on start-up and reloaded I hadn't invaded any players but Varre acted like I had followed the steps of his quest and the three invasions and he gave me the pureblood knights medal.
This means anyone on a + playthrough can quickly and easily get access to the fat coinpurse rune farm down the hill from the palace approach ledge-road grace.
