The Scale Armor is a set of armor added by the Hexxit Gear mod. It is one of three sets of Hexxit Gear Armor. When fully equipped, the player receives Strength, Resistance and Fire Resistance II potion effects that last as long as the player keeps all four armor pieces equipped as well as the maximum 20 Armor Points, the equivalent to wearing full Diamond armor. It is also the armor with the best overall defense.
This armor set gives Fire Resistance II, which has no difference from Fire Resistance I. Fire Resistance II is used because in Java, the level input (1 in this case) will have 1 added to it in the game
Even though the amount of armor points is maxed out, making it look about as good as diamond (but less durability), it gives you Resistance I with the full set, therefore being better than diamond raw defense-wise (not taking into account the Fire Resistance and Strength).
The full set of armor is dubbed the best for melee battles, due to the Strength, Resistance and Fire Resistance buffs.
