The Ice Bank is a building unique to the Polaris tribe that produces 3 stars per turn for every 20 frozen tiles in the world. The Ice Bank is unlocked with Trade and replaces the Customs House.

The Ice Bank costs 20 stars. The level of the Ice Bank depends on the number of frozen tiles, including both frozen land and Ice, in the world, regardless of which Polaris player froze the tiles (in games with multiple Polaris players). The Ice Bank automatically levels up as more tiles are frozen up to the maximum level 10. Each Polaris player can only have one Ice Bank.
