Warlocks: Fel Armor has been redesigned. It now surrounds the caster with fel energy, increasing spell power and causing the warlock to be healed for 3% of any single-target spell damage he or she deals.
Items: The Honor Commodities and Justice Commodities Vendors now sell raw tradeskill materials. These are not intended to be a cost-effective source of these world of warcraft gold, but an option for players with lots of Justice or Honor Points who have already purchased all of the gear that interests them.
Lich King trinkets with bonus armor values have been adjusted using the new Cataclysm formula, reducing their armor values substantially. The PvE hunter 4-piece set bonus has been redesigned. It now reduces the cast time of Steady Shot and Cobra Shot by 2 seconds. All PvP 4-piece bonuses have had their flat stat values cut in half. Primary stats are very powerful in Cataclysm, so much so that players were considering using PvP gear in PvE just because of these primary stat bonuses. PvP enchants are properly valued and attached to Honor Quartermasters and Tol Barad/Baradin Hold Quartermasters.
Archaeology: The sell value of all common artifacts has been doubled, while a small subset of common artifacts have had their sell value increased far beyond that wow gold. Engineering: Mystic Cogwheel is a new Engineering Cogwheel gem which provides resilience rating and can be purchased from the Engineering vendor for 55 Honor Points. Synapse Springs now increase Agility, Strength, or Intellect. In addition, the effect now lasts 10 seconds, down from 12.
