As glad as I am that you patch bugs, this one was so incredibly useful that it makes me wonder if you’ve ever considered increasing the time it takes to sacrifice an NPC on the Sacrificial Stone, or making it skippable.
The ritual takes too long when you take into consideration the amount of blood flasks that are needed for sorcery, such as Leather Pouches and Summon Corpse, etc.
Just thought I’d drop this suggestion here.
