One of my players asked a very interesting question. Their playing an alchemist. Their wanting to know how their communal extracts works, and Im having a hard time coming up with an acceptable answer. The main issue is a conflict between
An extract is “cast” by drinking it, as if imbibing a potion
Target creatures touched
There is also
In effect, an alchemist prepares his spells by mixing ingredients into a number of extracts, and then “casts” his spells by drinking the extract. When an alchemist creates an extract or bomb, he infuses the concoction with a tiny fraction of his own magical power—this enables the creation of powerful effects, but also binds the effects to the creator
The alchemist is clearly given the communal spells because of the formula list, but the question is more about how to have it take effect. Does he drink part of his extract then pass it around? Does he swish it around in his mouth and spit it back into the flask for the others? Does he drink and touch people? Does he shake the flask and spray it around like Champlain?
The class for the most part seems pretty specific that whatever the alchemist makes is for themselves (baring the infusion discovery). So how do the communal ones work?
