I just set up a server using valhelsia 3 and the soul extractor doesn't seem to have a recipe. I managed to find a video with the recipe (utrem jar, 2 nether bricks, block of quartz, and nether quartz) but it doesn't have any output. Only Item I haven't been able to make.

Descovered that Valhelsia was using an old version. Updated it and can now make the soul catcher!
