The full Thief Armour Set equipped (with a nice house in the background)
Thief Armor is part of the Hexxit Gear mod. It is one of three sets of Hexxit Gear Armor. When all four parts of the armor are equipped, the player will experience special abilities, as well as giving the player the maximum 10 Armor Points, the equivalent of wearing full Diamond armor.
Once all four pieces of armor are equipped, the player acquires unlimited Night Vision and Strength potion effects. You also gain an incredible speed boost. The speed boost will work even on a chocobo so it is recommended to take off a piece of the armor before riding a chocobo (the world may not load fast enough to go that speed and may also cause lag). There is a bug with this armor involving Dimensional Doors. If you enter a Dimensional Door with the night vision buff, everything will appear completely black until the buff expires. Only particle effects, such as torch flames or notes from note blocks, will be visible. The Tribal Armor also shares this bug.
