Armour
Armour is a set of equipable defense items that provide gear level and reduce damage taken from enemies and players. Armor pieces are equipped by placing them in the armor slots of the player's inventory. Armor pieces are crafted through Inventory Crafting Tab, Simple Workbench, or Tailoring Bench.
Each piece of armor has a gear level that indirectly reduces damage by Damage% = Gear Level/Enemy Level. However it should be noted this does not apply for PVP. Also, each armor provides with flat health.
In addition to the health and gear level provided by individual armor pieces, some armor types provide a Set Bonus when all two or four pieces of the same armor type are worn simultaneously. For example, Bloodmoon armor set is one of 4 armor sets that provides set bonus.
Over all, there are 8 different armor sets obtainable and 4 of these provide set bonuses.
