Some info I happened upon from publish 81:
Armor Revamp
Armor Stamina Loss Update:
Player’s stamina loss will now be based on the type of armor as well as the amount of armor that is equipped. Each piece of armor up to five pieces will reduce the amount of stamina lost when taking damage. The armor pieces which provide the most stamina loss reduction will take priority.
- Cloth armor, leather armor, and jewelry will give the same stamina loss reduction as Pub 80.
- Blacksmith armor (platemail, ringmail, chainmail, and dragon armor) will provide a heavy bonus to stamina loss reduction.
- Studded leather armor, stone armor, bone armor, woodland armor, and hide armor will provide a light bonus to stamina loss reduction.
Human racial ability Tough now provides a small bonus to stamina loss reduction.
Armor Inherent Lower Mana Cost
Each piece of non medable armor will provide lower mana cost with the exception of woodland armor. Each piece of armor up to five pieces will provide a percentage which is not subject to the lower mana cost cap of 40. The armor pieces which provide the most lower mana cost will take priority.
- 1. Platemail, ringmail, chainmail, and dragon armor provides 1% of lower mana cost per piece.
- 2. Studded leather, hide armor, stone armor and bone armor provides 3% of lower mana cost per piece.
