Prospector's references

In a world of environmental oversight and trade restriction, prospector's references allow industrial boon for the everyday digger looking for an advantage. The references increase the mine ownership capability of their owners:

• Prospector's almanac increases capacity by 1 mine
• Prospector's guidebook increases capacity by 2 mines

The references are sold at the Tradeskill and Crafting Artefact Shop located in Delos.
