Organ Improver 
The white-skull Organ Improver is an alchemy result with four green runes. In the full game it turns any skin, bones, skull, heart, brain or guts into the version of that organ with the most white skulls, 3 of them, at the Formulation Bench. White skulls are what a buried body’s grave quality is capped by (see Graveyard).
The demo cannot build the Formulation Bench, so there a mix only gives 4 green tech points and progress toward the Alchemist inspiration. At the Laboratory I it is easy to make: 2 Flour, 2 Onions, or one of each.

Notes
- The other Organ Improver (red skull) does the same for red skulls.
- The town Alchemist sells it from its second tier in the full game.
- Studying it costs 15 Science and gives 10 green and 50 blue.
