Barriers

Magical barriers block enemy's spells and items to your country. Requiring certain formula and technique, only an Archmage can build a barrier. There's no way to order anything when you are concentrating to build them. Higher rate of barriers will increase the chance of protecting yourself from various kind of magical attacks.

Building barriers:

• If you build 50 barriers at once you will pay upkeep for 50 barriers for 50 turns at a cost of 2,500 mana in upkeep alone.
• Building them one turn at a time saves you 1,250 mana.
  • of course the faster you move, the less you risk being attacked while building barriers...
