Loken ( tactics ) Loken appears in " World of Warcraft " as the final encounter in the Halls of Lightning . Quests . His death is the objectives of in which players are sent to slay him and take his tongue . Tactics . Lightning Nova and Pulsing Shockwave . In order to reduce the damage taken from these two abilities , correct positioning and movement is required . The Pulsing Shockwave forces the group to generally stay close to the boss , but whenever he starts casting Lightning Nova ( which is announced by an emote ) , players must run away 20 yards . The group needs to agree beforehand on a run path . A frequently chosen pattern is the bright line on the stairs leading from Loken ' s initial position to a platform and from there further down another flight of stairs . On the pull everybody runs to Loken ' s initial position , on the first Lightning Nova everybody runs to the platform , on the next back to his initial position . This method has the drawback that people dying on his initial position can be difficult to rez , for this reason it ' s better to run on the second Nova further down to the end of the stairs , and then back to the platform . Moving on the stairs has the general disadvantage that it can cause line of sight problems for the healer . For this reason some groups prefer to run from side to side on the platform where Loken starts ( there are pillars on each side of him as reference points ) . Arc Lightning . This boss ability has the potential to cause severe damage to the group when people stay close together . If the initial target gets the debuff and all others are within 10 yards , the probability is very high that at least one other player gets the debuff , leading to a nearly neverending chain of Arc Lightnings . To avoid this people need to stay 10 yards apart from each other at all times ( this partially conflicts with the positioning required to avoid Pulsing Shockwave ) . Alternately , players with the debuff can try to run away from the group . Alternate Strategies . The problem with running around is that it greatly reduces both healing and DPS , and may cause confusion . So if the healer is able to sustain about 3600 hitpoints healed per second for two minutes , all group members have over 14k health ( the tank over 25k ) , and some form of nature resistance is available , it ' s possible to simply stay in melee range of the boss and not move at all . The healer in this case must AoE spam heal . This variant works particularly well with a Shaman healer ( Riptide buffed 4 jump Chain Heal plus Nature Resistance Totem ) , quite a few groups with shaman healers report success killing Loken in under two minutes for the achievement using this tactic . Average as of patch 3 . 3 is around 30 seconds using the random dungeon finder . On Heroic level , this should be preferred tactics when all members have 19k health ( shield absorption incl . ) or better ( tank about 30k + ) . AoE healer a must , preferably priest with Spirit of Redemption talent , since the fight should be very fast ( 2mins or less = 3 Nova blasts ) . Often a Paladin ' s Judgement of Light can handle most of the Pulsing Shockwave ' s AoE , assuming that players stand at minimum range . Always good with 2 rezzers to rezz priest , since there will will be casualties in last Nova blast . If party members are below 16 - 17k at blast they will die . Highly geared players , especially with Heroism , can blast Heroic Loken in less than 30 seconds , in which case they only need to worry about one Nova . If the healer sports some integrated self - heal ( Paladin or Priests ) the following tactic may be appropriate : Loken is kited on his platform as in the standard tactic . The healer is placed 20 yards away from both tanking spots , resulting in a triangle : the two tank spots are two corners of the triangle , connected by the 20 yard run path , the healer stands on the third corner of the triangle , 20 yards away from both other corners . This way , the healer continuously takes damage from Pulsing Shockwave which must be healed through ( abilities like Beacon of Light or Binding Heal facilitate this ) .
