Grace of Gloom is a heavy armor set. When you take damage from a single target attack or ability, you have a 10% chance to become a living shadow, causing your Light and Heavy attacks to heal you for 3440 and gaining Major Evasion for 5 seconds, increasing your dodge chance by 15%. This effect can occur every 15 seconds.
Grace of Gloom is part of the Summerset chapter and drops in Summerset in the Overland content. You can also find it on Guild Traders. Each set item is bound on equip. You can acquire heavy armor, jewelry and weapons for this set in the Ebonshadow motif style.
