I - Rules
(see RTL, p. 21)
The Alchemist buys and sells potions.
Visit, Train, or Restock
A hero may buy potions for 50 coins each, or sell potions for 25 coins each. A city’s Alchemist rating is a limit on the total number of potions that all heroes collectively may purchase there in a given game week. Remember that invulnerability potions (introduced in The Altar of Despair) are not used in the Advanced Campaign, and cannot be purchased at the Alchemist.
