Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General A Use for Those Blood Roses

In the book of Radeka's zombie was written a recipe where you should fill 3 roses into a perfume bottle to get something special but it didn't work for me despite I had 3 roses and the empy perfume bottle (but you can't stack the rose from the torturer with the other two from the Radeka cave).
