Prerequisite: Alchemist 12
Benefit: Once per day, the alchemist can dilute any one potion or elixir, creating two doses of the same potion from one. Diluting a potion costs a number of gp equal to one-quarter of the potion’s market value. A potion that has been diluted cannot be diluted again. This discovery cannot be used to dilute extracts or mutagens.
