Kael ' thas Sunstrider ( Magisters ' Terrace tactics ) Kael ' thas Sunstrider is the final boss of the Magisters ' Terrace in Patch 2 . 4 . 0 . Note : As of patch 3 . 0 . 3 , this instance is far simpler than it used to be . Heroic Only : Strategy . Phase 1 . At the start of the fight , Kael ' thas will largely stick to melee , as well as throwing out the occasional Fireball . If you have no one in melee range , Kael will resort to casting spells instead . Fire Resistance isn ' t necessary , although a bit of it ( from a Paladin Aura or a Fire Resistance Totem ) will help . Kael ' s casts can also be interrupted so players with silencing abilities should be sure to interrupt his Fireball , and a single shaman can avoid almost all damage from fireballs by alternating grounding totem and earthshock . However , it is not possible to interrupt the Flamestrike , Phoenix , or Gravity spells . He also uses Flamestrike which is easily avoidable , but will kill you if you stand in for the initial hit . You should kill the bird and the egg before Kael ' thas reaches 50 % . Managing Phoenixes Ten seconds after combat begins , Kael will summon a phoenix , and will continuously summon new ones every minute for the duration of the first phase . When a phoenix is out it needs to be beaten down quickly ( with ranged damage ) , by at least two party members . The phoenix should be kited away from the tank and Kael , as it will eventually explode when it dies , dealing tremendous damage and throwing nearby players backwards . Once it dies an egg will spawn in its place , which will very soon hatch and respawn the phoenix if it is not destroyed . A total of two phoenix spawns are almost unavoidable for most groups . Take Kael to 50 % to start Phase 2 " after " the second phoenix egg is broken ; having even one phoenix up during Phase 2 is an almost guaranteed wipe . To minimize the damage Hellfire causes to players that the phoenix passes , you should plan out positioning and aggro . Phase 2 . Phase 2 begins when Kael ' thas hits 50 % health . After a few seconds , Kael ' thas will cast Gravity Lapse , which will throw your entire party into the air and allow you to float freely around , much like the fight with him in Tempest Keep . He ' ll begin channeling Arcane Energy onto your entire group , which deals 300 damage every second for 30 seconds . He will also summon three Arcane Orbs , which will hit you in melee range for around 2k + . It is thus vital for your party to swim around and avoid the orbs . It is a good idea to move outward immediately , while still trying to DPS Kael ' thas as much as you can . A healer with an AoE , such as a Priest , or HOTs like Druids , is tremendously helpful for this fight , whereas Paladins and Shamans will have extreme difficulty keeping an entire group alive due to the nature of their healing . There is no tanking at this point . Ranged DPS may continue firing upon Kael as opportunities present themselves , but the priority is to above all give the orbs a " wide " berth . Phase 3 . After 30 seconds Kael ' thas will tire and Gravity Lapse will end , giving you a few seconds to freely attack Kael without reprisal . Kael takes 50 % more damage in this state . After 10 seconds , he will get back up again and re - cast Gravity Lapse ( repeat Phase 2 ) , so try and do as much DPS as you can while you have the chance . Again , tanking does nothing . It is possible for classes with at least 1 healing spell ( such as an Affliction Warlock ) to solo the boss for the remaining 50 % on both Normal and Heroic , as Kael will no longer use direct attacks . For this reason , do not assume that your group has wiped if you lose some members during the encounter . Thus as long as there are any remaining survivors , do not release your body if you die during the encounter , lest you not get credit for the kill while you return back in spirit form . Alternatively — if you feel confident that the battle will last long enough , you can safely walk back , and will be transported back to the room Kael is in when he recasts gravity lapse . Heroic . In Heroic Mode , Kael ' s damage with Fireballs and Flamestrikes is increased . After sixty seconds ( and if still in phase 1 ) Kael will use the Shock Barrier ability ( identical in behavior to the one he uses in Tempest Keep , and similar to the Priest in the Maulgar fight ) , which will absorb 10 , 000 damage . When the shield has taken the 10 , 000 damage , it will disappear and allow someone to interrupt the Pyroblast that he is casting . The Pyroblast will kill any tank that lacks sufficient spell damage reduction . It is very possible ( especially with Bloodlust / Heroism ) to take Kael to phase 2 before this time has elapsed , and if done he will not cast Pyroblast . Also note that the 60 second delay is perfect for a Warlock to time a Curse of Doom to hit during the shield , making it trivial to interrupt . Paladins should bubble ( after he has started casting ) and then use Righteous Defense on Kael ' s target at the last second of the Pyroblast cast to prevent all damage and save a character from certain doom . Warriors can use Shield Wall and Last Stand to survive it ( Spell Reflect will not work ) . Druid tanks are out of luck . Note that the tank dying to the Pyroblast does not mean the group will wipe . Usually Kael ' thas will hit 50 % shortly after the Pyroblast and start phase 2 . A tank is unnecessary in phase 2 since Kael does not move and does not directly attack . Alternative . Phase 1 Line of sight the pyroblast . After interrupting a fireball , drag him over to the wall near the start , then when the pyroblast beings to cast , run around the corner , it will be canceled , and he will go back to casting fireballs . If you have no one to interrupt , tank him where he starts , and then run around to the back of the room when the pyroblast starts . Phase 2 & 3 Same as the other strategies . Stay away from the Orbs and DPS down Kael as much as you can . Good luck ! Alternate Phase 2 Strategy . This works both in regular and heroic modes . Once phase 2 occurs , everyone should swim to the door near the ground , but not touching it as it will cause you to get shot up . Have the healer top everyone off while the orbs slowly make their way to the group . Since the group has several seconds before the orbs reach the group , this strategy works for all healer classes since the healer can remain stationary , heal , and know that everyone is within range without having to worry about the orbs ' AoE damage . Once the orbs get close , have everyone swim around / above the orbs and get close to Kael ' thas and start to dps . If timed correctly , the orbs will not have time to reach the group and the healer will still be able to remain stationary and heal without worrying about the orbs . Phase 3 should occur shortly and then back to phase 2 . Rinse and repeat . Healing Tips . Phase 1 is relatively easy to heal for any class , so long as people are not taking the damage that ' s avoidable ( flamestirke and hellfires ) . Kael ' s burst damage , especially on Heroic , is powerful but predictable . Solicit the help of any rogues / shaman to interrupt Kael ' s fireballs , and if you have a warrior tank , remind him to Spell Reflect and Shield Bash as often as he can . Phase 2 of this fight , however , is the epitome of a Healer Check . Provided no one hits the bubbles and causes undue stress on their healer , either the healer has the skill , mana efficiency and gear to heal through the ticks , or he doesn ' t . Very little else is a factor in phase 2 , as a good healer can technically solo Kael from 50 to 0 . Tree of Life is a good healer because it has many HoTs and many of them are instant , and this makes healers job easier at Gravity Phase . Holy Priests are also exceptional healers this fight once Phase 2 begins . Make frequent use of Prayer of Mending and stay close to at least one other party member . It will exhaust itself in 5 seconds , restoring a great deal of health . Spam it every time it pops . During Gravity Lapse , rely mostly on your Hots and instant cast spells . It is dangerous to stay in one place very long . If you have good + Healing , this shouldn ' t be a problem . At the end of Gravity Lapse , use this time to top of your party with Circle of Healing , Prayer of Healing or Chain Heal , as insurance against someone touching a bubble in the next air phase . All DPS should be within range of your spells during this time . Prioritizing Targets in Phase 2 A party member ' s death is both a blessing and a curse - while you will have less DPS on Kael , you also will have less damage to heal as Kael ' s Arcane Bolts will only be draining 4 members , reducing your chances of going OOM and killing everyone . Priorize your targets as follows : 1 . Yourself The healer is , by far , the most important target here - if you die , it ' s most likely a wipe . 2 . DPS Warriors / Rogues / Warlocks / Enhancement Shamans They are non - mana dependent ( or much less mana dependent ) DPS , and will still be fighting at 100 % efficiency , even if it goes 10 Gravity Lapses . 3 . DPS with Mana They are vital , but can run out of mana . Not as important as the others . 4 . The Tank After Phase 2 , the tank is no longer a factor - he ' s just a bad DPSer . If it ' s between almost anyone else , and him , let him die . 5 . OOM DPS At this point , they are mana / time sinks for you . Heal them as a last resort . Paladin Healing Paladins will need to be able to squeeze every bit of healing out that they can , as they are arguably the least optimal healers this fight , with only 1 instant cast , mana inefficient heal on a cooldown , no hots and no group heal . It ' s a good idea for Paladin healers to throw Blessing of Light on everyone during the seconds between when Kael says : " I ' ll turn your world . . . Upside Down . " and while being launched into the air . You will be hard pressed to heal while in the air , and will need to make the most out of each opportunity . Use Divine Shield if the majority of your party has fallen below 50 % life , even if you are healthy . Position yourself in the middle of the room to do this . This will give you range on all your party members , and allow you to heal without fear of the bubbles for 15 seconds . Use Flash of Light and Holy Shock while in the air to keep as moble as possible . You will be amazed at how fast bubblse can creep up on you if you try for Holy Light . Save Holy Light for when Gravity Lapse ends , as you will want to top everyone off before the next Gravity Lapse . If you use Divine Shield just before Kael casts Gravity Lapse you will not get thrown into the air . This makes it significantly easier to heal your party as you can move faster while on the ground as well as avoiding the couple of seconds it takes to re - orient yourself when thrown into the air .
