Freya ( tactics ) Freya is one of the boss encounters in Ulduar , similar to Sartharion when it comes to her hard mode . She is in the center of the valley in Ulduar , surrounded by three ancients which all have unique abilities that will make the fight harder if players choose not to kill them prior to fighting Freya . Strategies . The fight takes place in a lush oasis - like valley inside Ulduar . There are three Elder boss - tree mobs you can choose whether or not to kill . They are similar to Sartharion ' s hard mode : if you choose not to kill them , the fight gets considerably harder as each elder buffs Freya and her adds . As you engage Freya , she will cast a HoT on herself and a buff that increases her received healing by 4 % per stack , starting with 150 stacks for a total of + 600 % healing which makes her basically invincible at the beginning of the encounter . Freya will then spawn six waves of adds in a fixed interval of 60 seconds . Defeating these waves will remove various amounts of stacks from her buff until it is completely removed by the last wave . The waves are of three different types , cycling through twice in a random order . The fight hinges on controlling the adds . Having said that , add - killing is far more central to this fight ' s strategy , as it is essential that adds are killed not merely because they will wipe the raid if it is overwhelmed , but also because in order to beat Freya ' s healing versus damage dealt to her , the adds must be killed . Throughout the whole encounter a slim , glowing tree called Eonar ' s Gift with 65k ( 20k in 10 - man ) HP will spawn somewhere near to Freya about every 45 seconds . It will grow for 10 seconds after which it will heal Freya and all her summoned adds in the zone for 60 % of their maximum health ( 30 % in 10 - man ) . This tree should be killed immediately by a few designated spotters or else killing the adds within the 60 seconds time to the next wave becomes a lot harder . Phase 1 . Every minute waves spawn in a random order : Wave Type 1 : Storm Lasher , Ancient Water Spirit and Snaplasher . They have varying HP from 500k to 1M and yet they all need to be killed at about the same time , otherwise 12 seconds after death they resurrect ( reminiscent of the High Priest Thekal raid boss adds ) . All three adds can be stunned and interrupted . Reduces Attuned to Nature stacks by 10 each . Unlike many mobs , Snaplashers ( on 10 - man ) will not melee a target next to them if the person highest on their threat list is out of melee range . In a melee - heavy raid , the DPS can work on the other adds first while the tank builds up threat and periodically lets the debuff fall off . When ready , the tank can simply walk away and the other DPS can hit the snaplasher with impunity . Another option is to kite the Snaplasher with a high - threat class like a hunter , helped by any slowing ability ( Slow from Arcane Mages , Hamstring , Crippling Poison , etc . . ) . This way you can go all out on DPS on it , as it has the highest amount of the three , and completely cancels the effect of its debuff ; this method also frees up a tank so in a typical 3 - tanks raid allows better control of the other two adds . Wave Type 2 : They have 234k HP , are untankable , and randomly run from player to player . When one dies it does a short ranged AoE for 8k ~ ( around 15 yards ) which makes AoEing them all at once on one spot a bad idea . Reduces Attuned to Nature by 2 stacks per mob . Wave Type 3 : She will also spawn a bigger add at some point , an Ancient Conservator with 2 . 2M HP . This is wave type 3 . Just off - tank him and kill him to remove 25 stacks from Freya . He periodically uses Conservator ' s Grip to silence and pacify all members of the raid . Staying under the Healthy Mushrooms that spawn during this time in the zone will remove and protect against this debuff . A paladin using Aura Mastery with Concentration Aura can offer temporary protection from this debuff if no mushrooms are near . He can also cast Nature ' s Fury on a random player who will damage all nearby players for 10 seconds , so he should quickly move away from the rest of the raid . Reduces Attuned to Nature by 25 . Phase 2 . The waves will stop spawning , Freya has the same abilities as phase one with the exception of the healing augmentation buff . It is a tank and spank phase . Freya will begin throwing out Nature Bombs in this phase and raid members must be careful to move away or they can prove lethal . If too many raid members are lost it may become impossible to DPS through Freya ' s Touch of Eonar . Normal mode . To engage Freya in normal mode you must kill the three Elders within the area before engaging her . The three Elders are easy mini bosses but require a little strategy to kill smoothly . Make sure to clear out any trash mobs between the mini boss and freya as it ' s easy to gather a patrol while moving around on the mini bosses and have them link Freya into the fight . Hard mode . The Elders , left alive prior to engaging Freya , do not engage combat , but banish themselves and provide the following buffs , while granting Freya some of their abilities as well : Suggested Elders to leave up : Quotes .
