An Injection for Zombies adds red skulls to a body and takes off as many white ones, 1, 2 or 3 of each by grade. You make it at the Formulation Bench from an Alcohol, a Preservative and a Comet’s Tail, with Anatomy mastery 8, after Embalming III (150 red, 150 blue) on the resurrection branch.
Each item is studied once, on the Study Table. Studying does not use the item up. With the Scientist perk, a 30% chance of a Story.
Notes
For a zombie it does the same job as the Solution for Zombies. Zombies make no use of white skulls, so the extra effect changes nothing, while the injection costs a Comet’s Tail and more mastery.
On a corpse you mean to bury it is doubly bad: more red skulls and a lower ceiling.
At Anatomy 8 every bottle comes out grade III. The town Alchemist sells grade I from its first tier and one grade III a week (80 silver) at its third.
