This text, written in Ancient Arathian, is difficult to translate even for one familiar with that dead language, as it contains lengthy, erudite passages featuring complex alchemical terminology using what appears to be a heavily modified version of the long-defunct Sarkasian nomenclature.
ELETRO-ALCHEMICAL DISTILLATION OF ARCANO-CEREBRALITE POTIONS
“The arcanists’ mind – both physical and ephemeral – is laced with the highly potent potential of the vast energies they harness and hook through their personal cerebral cortexes. Like all energies of life, these are not instantly dispelled upon death, but instead dissipate lingeringly over time. If the brain can be harvested in due course and before this final dissipation occurs, the occult energies can be salvaged.”
PRESERVATION: Part of this text describes how an arcanist’s brain can be surgically removed without disturbing the nascent arcane energies of their currently prepared spells (requiring a DC 18 Wisdom (Medicine) check) and then preserved through the use of an alchemical bath (25 gp in material costs, DC 12 + highest spell level to be preserved Intelligence (alchemist’s supplies) check).
PULPING: The rest of the text describes how the brain of a freshly dead arcanist (within 24 hours) or a preserved arcanist’s brain can be pulped using a three-dimensional mortar and pestle in order to create potions from the spells they had previously prepared.
This process is complex, requiring an Intelligence (alchemist’s supplies) check at DC 15 + spell level for each spell withdrawn from the brain. The alchemical supplies cost as much as it would normally cost to brew a Rare potion, but without the need to expend spell slots or meet other prerequisites. The process also only requires one day of effort.
There is no limit to the highest level of spell that can be turned into a potion using this method.
DETERMINING SPELLS: In order to determine exactly which spells were prepared by the arcanist, an alchemist can use a detect thoughts spell and make a separate Intelligence (alchemist’s supplies) check (DC 10 + spell level) for each spell. On a failure, there’s a 25% chance that the spell energies have been disrupted and lost. On a success, the alchemist identifies the spell (which will then allow them to know exactly what the pulped potion they prepare will do).
POTION EFFECT: Brain pulp potions are distinct from other potions due to their eponymous pulpy texture. Drinking a brain pulp potion will either immediately allow the drinker to benefit from the spell’s effect or allow them to immediately use the spell effect as if they had cast it.
