From publisher blurb:
Arcana & Mechanica is the lastest expansion for The Gloom. This short expansion is mainly a revision of the Wand athame to make it simpler and more focused. The athame has been split in two—the Wand, which focuses on magic, and the Pistol, which focuses on tech.
The book includes the following:
New/Revised Athames
The Wand emits energy and gives the user a greater aptitude for investigation and magic.
The Pistol shoots bullets and provides the user with insight into technology, including the magical technology called “mechanica.”
Revised Arcana Rules
Arcana has also been revised, particularly Divination and Warding.
This book also includes the potions, elixirs, and mechanica in The Gloom, but it is only for connivence—no revisions have been made to the items.
