Well, since I was going to craft faust, I wanted to get myself some curse defence. I went to Brinks, but then I noticed a bug about silver amulet staistic and sacred silver amulet statistic. The problem is, that sacred silver amulet statistic shows that it provides as same curse defence as silver amulet! Of course, sacred silver amulet still costs 50 grim sparks, while silver amulet costs only 5 grim sparks. Here's a photo of statistics (2 screenshots cut into one).
