What is War Harbor?
War Harbor is the commercial port for seasoned Warlords. War Coins earned in PvP can be traded in for useful items (for example Shards or Gold) here.
War Harbor resets twice a day, like the Dwarf Merchant. You can also choose to refresh for 50 Diamonds at any time.
War Harbor also has items on sale regularly, so make sure to check out their offers frequently.
