Hist Bark is a craftable set. While you are blocking you gain Major Evasion, decreasing the damage you take from area of effect abilities by 25%.
Hist Bark is a very popular set for beginner tanks because of the bonuses to Health, Resistance, and dodge chance. Note: Do not slot an ability that gives you Major Evasion while wearing this set, since 2 like buffs do not stack (a Major buff does stack with a Minor buff, however).
Hist Bark is part of the base game. The crafting stations are located in Greenshade (Rootwatch Tower), Rivenspire (Trader's Rest) and Shadowfen (Hatchling's Crown). You can craft any armor, weapon or jewelry of this set in any motif style you know, as long as you have 4 traits researched (per item). You can trade crafted pieces to other players. Each set item becomes bound on equip.
