After you kill the last Barbarian, you have 20 minutes of "Occupying" status. You must leave your units there.
Stop fighting your neighbors for a single marble mine. Go sack the Barbarians. Your Treasury will thank you. Have a specific Barbarian level you’re stuck on? Drop the details in the comments below and I’ll build a custom kill-sheet for you.
If you’ve been playing Ikariam for a while, you know the drill: build your marble quarry, secure your wine, and fight off human pirates. But eventually, you’ll look at that swirling, dark icon on the map—the Barbarian Village —and wonder: Is it worth the bloodshed?
