Shielding

Shielding is a skill like Axe Fighting or Sword Fighting and decides how well you can stop Melee hits from creatures and other players (on PvP worlds). Knights will advance the fastest in shielding, faster than any other vocation. Druids and Sorcerers, will advance the slowest, and rarely get a skill much higher than 25~30. Paladins are more in the middle.

To train your shielding you need to have creatures attacking you while wearing a shield. Your shield can only block two creatures at max, so more than two will not help to train your shielding.
