How does Beastmaster's Catgoblin resource extraction work exactly?
Do they extract resources passively the same way they go about gathering them?
Is a digging squad supposed to dig around resources, extract resources, or both?
Do the digging squads exist separate from your normal Catgoblins? If you try to summon a squad when they are all busy does nothing happen?
Which upgrades do I need to get the most out of catgoblin extraction? More Catgoblins? More squads? Faster digging? Less downtime?
I'm trying to do Iron Challenge with Beastmaster utilizing the Efficient Catgoblins supplement.
