Clarifications:

• Remember: Whenever you complete a task, you gain 1 Resource from the supply. See Complete a Task for details on what counts as completing.
• You can purchase multiple Tools and/or Allies at once. See Focus for details.
• Resources are unlimited components. If you run out of them, use regular dice or coins to represent them temporarily.
• There is no limit for how many Resources you can have.
