Archimonde's VengeanceEach time you or your pet take damage, you gain 1% of the unmitigated damage taken as spell power for 20 sec. Warlock - LvL 90 Talent. Your Dark Soul spells have two charges. Warlock - LvL 90 Talent.
With this change to locks, and the changes to rogues, I can see RLS being really good next patch.
All of these are on mmo-champion's front page atm.
