The Harvester is a small resource unit for the Substrate.
Economy unit. Move to a Generator to increase its base income by 15%. Multiple Harvesters can enhance a region.
The Harvester travels to regions and gathers resources, even if the region is unclaimed or belongs to another player. The Harvester's resource rate is much less efficient than Extractors and Amplifiers, but there's no limit to how many Harvesters can collect resources from a region, making it useful in the late game to continue increasing resource output. Harvesters draw resources relative to the amount of Extractors on a region.
