From Age of Aincrad Wiki
Shield are one-handed equippable defensive items, which can be used with one-handed damage equippable items to raise the amount of armour the player has and the amount of damage he/she is able to take.
Information on shields
- There may be some skills which will allow the players to wield two shields in both hands simultaneously, raising the players' defence even more.
- Shields will be probably used mostly by tanks, as they are going for the highest attainable defence possible.
- Shield users will play a major role in every boss fight, as without their help most players could be stomped by high damage dealing opponents.
