You gain three extra potion mixing slots per adventure.
Fuelled by Ichor
You may consume pure black ichor transmuting it within your body to produce the effect you desire.
You may consume 1 dose of ichor to produce the effect of any potion you know how to make.
This takes a toll on your mind, costing 2 psyche.
Berserker Serum
Twice per adventure you may with 10 seconds roleplay apply special serums to a willing or unconscious individual. This temporarily boosts their physical capabilities far beyond their natural limits.
The individual takes all damage as singles and is IMMUNE to REND.
They are driven into a blind rage however and must always attack the nearest enemy (if available) or otherwise, their nearest target.
This lasts until the end of the encounter.
Potion Tolerance
You can drink 2 additional potions per encounter without suffering any ill effect.
However, taking a rank of this skill means that your body begins to mutate.
