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.

Effects

• The percentage of barriers on your land determines overall spell resistance
  • Building ~2.5% barriers gives the maximum 75% barrier resistance
  • The skill Barrier Proficiency can raise maximum resistance to 83%.
• Barriers require 30 m.p./turn upkeep on non-oversummoning servers, and 60 m.p./turn on oversummoning servers
• Barriers provide no space for population, vs 10 for wilderness.

Building barriers

• The number of Workshops does not increase the building rate for barriers (these are magical buildings, only the mage can make them)
  • Neither does the Engineer (these are magical buildings, only the mage can make them)
• If you build 50 barriers at once you will
  • first pay the building cost 50 barriers times 50 m.p. = 2500 m.p.
  • but also pay the upkeep for 50 barriers times 30 m.p. for 50 turns at a cost of 75,000 mana in upkeep alone.
• Building them one turn at a time saves you ~37,500 mana on upkeep mana.
  • of course the faster you move, the less you risk being attacked while building barriers...
