Age of sorcery build path

I recently started to play a game on windows phone, Age of Sorcery. Found out no one has posted its building upgrade path yet, so here it is, hopefully it can be helpful to other new players when they google: Academy => Shrine of fire 1 Academy 2 => shrine of wind 2 Academy 3 => shrine of earth 3 Academy 4 => shrine of fire 4 Academy 5 => City walls 5 Academy 6 => Shrine of Fire 5 Academy 7 => shrine of fire 6 Academy 8 => Castle 7 Academy 9 => Shrine of wind 8 Academy 10 => shrine of earth 10 House 2 => farm 1 House l3=> farm l2 House l4=> mithril 3 House l5 => farm l4 House l6 => Shrine of earth 1 House 7 => Academy 1 House l8 => warehouse l6 House 9 => City walls 7 House l10 => Warehouse l10 Warehouse 2 => Castle 1 Warehouse l3=> mithril l2 Warehouse l4=> House 3 Warehouse 5 => Shrine of Wind 2 Warehouse l6 => castle l5 Warehouse 7 => Castle 5 Warehouse 8 => house 7 Warehouse 9 => Castle 8 Warehouse 10 => City walls 9 Farm 2 => Castle 2 Farm 3 => Warehouse 2 Farm 4 => Castle 2 Farm 5 => Warehouse 4 Farm 6 => Shrine of Fire 1 Farm 7 => Academy 4 Farm 8 => City Walls 6 Farm 9 => City walls 8 Farm 10 => Warehouse 9 City walls 2 => Castle 1 City walls 3 => mithril 1 City walls 4 => farm 4 City walls 5 => House 6 City walls 6 => Warehouse 7 City walls 7 => Farm 7 City walls 8 => Mithril 7 City walls 9 => castle. 8 City walls 10 => castle 10 Castle 2 => House 1 Castle 3 => Warehouse 2 Castle 4 => City walls 3 Castle 5 => House 4 Castle 6 => Academy 5 Castle l7 => city walls l7 Castle 8 => Academy 7 Castle 9 => forge 5 Castle l10 => academy l9 Mithtil 2 => Warehouse 1 Mithril 3 => Warehouse 3 Mithtil 4 => Warehouse 3 Mithtil 5 => Academy 2 Mithril 6 => Academy 2 Mithril 7 => Castle 6 Mithtil 8 => city walls 7 Mithril 9 => Shrine of Fire 7 Mithtil 10 => shrine of fire 10 Shrine of wind => Castle 2 Shrine of Wind 2 => farm 3 Shrine of Wind 3 => mithril 3 Shrine of Wind 4 => mithril 6 Shrine of Wind 5 => farm 6 Shrine of Wind 6 => Castle 6 Shrine of Wind 7 => city walls 7 Shrine of Wind 8 => Farm 8 Shrine of wind 9 => Academy 9 Shrine of Wind 10 => Castle 10 Shrine of earth => Castle 3 Shrine of earth 2 => castle 3 Shrine of earth 3 => mithril 4 Shrine of earth 4 => Warehouse 5 Shrine of earth 5 => Castle 5 Shrine of earth 6 => forge 4 Shrine of earth 7=> forge 6 Shrine of earth 8 => Academy 7 Shrine of earth 9 => Academy 8 Shrine of earth 10 => Castle 10 Shrine of Fire => Castle 4 Shrine of Fire 2=> city walls 4 Shrine of Fire 3 => mithril 5 Shrine of Fire 4 => House 6 Shrine of Fire 5 => Castle 6 Shrine of Fire 6 => forge 4 Shrine of Fire 7 => Academy 6 Shrine of Fire 8 => Academy 6 Shrine of Fire 9 => Academy 8 Shrine of Fire 10=> Castle 10 Forge => Castle 7 Forge 2 => Shrine of wind 4 Forge 3 => Shrine of earth 5 Forge 4 => shrine of fire 5 Forge 5 => city walls 6 Forge 6 => shrine of earth 6 Forge 7 => shrine of wind 7 Forge 8 => Shrine of Fire 8 Forge 9 => city walls 9 Forge 10 => castle 10
