You can quickly turn the compounds and catalysts in your custom microlab into medicinals (Core Rulebook 231). You can create an analgesic, an antitoxin, or a sedative with an item level no higher than your biohacker level. If you are an instinctive biohacker, you can also make excitants and stimulants (Armory 133). If you are a studious biohacker, you can also make antiemetics and coagulants (Armory 132). These medicinals are highly unstable and cannot be stored for later use or used by anyone else. You can add one of these medicinals to any attack you make with an injection weapon as part of the action to make the attack or attacks, but you can’t add a biohack of any kind to the same attack. You can use this ability a number of times equal to your key ability score, and you regain all expended uses of this ability (up to your maximum) when you take a 10-minute rest to recover Stamina Points.
