Alchemist Achievement in A Plague Tale: Innocence
Craft 100 ammunitions
How to unlock Alchemist
Introduced in Chapter 4 through a tutorial, ammunition crafting is an essential part of the game as many areas and puzzles rely on crafting the correct types of ammunitions to overcome. Therefore though not story-related this should come naturally in later chapters. However, if you desire to speed up the process, the rinse-and-repeat method can be used to accumulate the required ammunition number.
Materials for ammunitions can only be picked up within chapters as there is no open-world or currency in this game, and thus it is recommended to fully explore the environment to collect as many materials as possible. Killed enemies sometimes also drop materials in small quantity.
