Bubble Bank Formula

This is a basic build/research order I used for the bubble bank. No Mithril was purchased, just the free Mith for getting a Kabam ID. Use it wisely and it will last to get the bank rolling. With a bit of focus you can have wagons rolling in under a day.

Remember to place the bank in a central location with the relocation rune, next to your old bank, preferably. Placing it by the old bank facilitates moving billions of res in a relatively short amount of time.

Here's the basic build order I like. Again, it's also my preference a bit. You can tweak it to suit you.

You can now start training wagons. Don't bother with porters, carts or troops. Train Wags to drop in 1 hour increments. Fill out the rest of the city with barracks. Level up Cartography and Tavern to boost march times during the week. Level barracks to decrease training times for wagons. Keep training wagons all week until you start your next bubble bank. Remember to give yourself a day of lead time before your bubble expires to build your next bubble or you can't march wags for a day.
