Armors of Hiraelia
There are five different levels of item quality when it comes to armor in the world.
Low Quality Armor
Low quality armor either carries a penalty to armor (-1) or to armor check penalty (+1) (randomly selected).
Low quality armors are abundant in shady areas of towns or at city exits.
As seen in the handbook.
High Quality Armor
High quality armor provides no increase in protection, but it moves more easily, granting a benefit to the armor check penalty (-1) of the item.
