Change the first paragraph of rule 2.1 “Commoner’s Economy” to:

Each Commoner has an Income (a number which can be positive, negative, or zero, and defaults to 50), and amounts of Coal, and amounts of Iron, Wood, Quicksilver, Caffeine, Cogs, Gems, and Electricity (numbers defaulting to the median values among Commoners, rounding up to an integer if necessary). Coal, Iron, Wood, Quicksilver, Caffeine, Cogs, Gems, and Electricity are collectively known as Resources.

Add the bullet point “0 Electricity” to the bulleted list in that rule.

Add a new subrule to Rule 2.2 “Inventions”, titled “Lightning Rod”:

Cost: 10 Iron
Power Requirement: 5
The owner of an invention which includes a Lightning Rod additionally gains DICE5 Electricity when Scavenging.

Set each Commoner’s amount of Electricity to 0.
