A consumable set is shorthand for one of each of the following three consumables: Grail of Might, Essence of Celerity, and Armor of Salvation. More commonly referred to as a conset, it is used by players to reduce the risk and/or the time spent completing any challenging PvE goal, e.g. vanquishing, speed clearing, elite areas (such as the Domain of Anguish), or Beyond.
Used together, a full conset provides the entire party with the following benefits: +100 maximum health, +10 Maximum energy, +1 to all attributes, 20% faster movement, attack speeds, skill activation, and skill recharges, immunity to 50% of critical hits, +10 armor, +1 Health regeneration, and damage reduction of 5 for 30 minutes.
