Ossirian the Unscarred Ossirian the Unscarred is a horusath and the last boss of the Ruins of Ahn ' Qiraj . History . During the War of the Shifting Sands , as the anubisath constructs crumbled under the bronze dragonflight ' s assault , a single anubisath did the seemingly impossible — he found a way to fight back . Ossirian targeted one of the leaders , the massive dragon Grakkarond , and hurled his obsidian sword through the beast ' s wing . The crippled wyrm descended , crushing the qiraji as it fell . The dragon mauled Ossirian nearly to death , but the remaining anubisaths and qiraji now had a target on the ground to focus on , and they swiftly converged and overwhelmed the noble dragon . Ossirian ' s beaten body was dragged back to the Ruins of Ahn ' Qiraj following the battle , where he should by all rights have perished . It is whispered that Ossirian found the favor of the malevolent force that reigns over the qiraji , for in spite of his wounds , the construct survived . When the mighty anubisath awoke , he found himself transformed , his strength bolstered and his wounded head bound in the visage of a hawk . Emperor Vek ' nilash himself explained what had occurred : Where all others — including the qiraji General Rajaxx — had failed to find a way to counterattack , the Anubisath had succeeded . For that he received a gift ; Ossirian ' s essence had been bound to several ancient crystals of distant origin , which would grant the Anubisath champion near invulnerability . There was a price for this boon however ; Ossirian ' s life was maintained by the crystals , and if he should ever stray too far from them , the Anubisath would swiftly die . As others learned of Ossirian ' s survival , the Anubisaths began to refer to him as the " Unscarred " , revering him as a nearly invincible hero . The legends say that Vek ' nilash secretly entrusted Ossirian with the responsibility of maintaining a watch on General Rajaxx , to ensure that the commander would never fail again . Ossirian serves the Emperors to the best of his ability , despite the frustration of being eternally bound to a single location . The bones of Grakkarond have become a sacred site to the Anubisaths ; a testimony to their ability to defeat even the most powerful of enemies . Abilities . Also note that when the encounter starts , a Sandstorm starts in all the instance making tornadoes harder to see . This does not stop once the encounter is over . Strategy . Before the pull . Ossirian deals little magical damage and as such the entire raid can have Amplify Magic placed upon them , as the increase in healing will greatly outweigh the slight increased damage from his AoE stomp . . This will make keeping the tanks up much easier as well as make HoT ' ing hurt people while running much more effective . Have the tanks stand up by the first crystal , behind it , and have the rest of the raid about 20 yards behind them . The Pull . Pick a raid member whose DPS will be missed least for the fight . Often , a naked mounted rogue will be used , although any class will do . Whoever is used ought to have a raid symbol put on them , to help the MTs . The puller , mounted , will body - pull the boss , then head back to the middle . Ossirian begins in supreme mode , hitting the tank for massive damage and moving very fast . When Ossirian reaches the bottom of the blue stairs on his platform , have a designated person click on the first crystal to activate it as he runs straight towards it . This can be a MT or anyone , it doesn ' t matter . The main tank should stand behind the first crystal and activate bloodrage and battleshout when Ossirian is pulled , to gain initial aggro , but he has to stay out of range until Ossirian is weakened or he is likely to be killed . Activating the Crystals . Activating the crystal will put a 45 second debuff on Ossirian that makes him hit for much less damage , slows him down , and puts a vulnerability on him for specific spell damages ( he can have more than one vulnerability at a time ) . Make sure you are paying attention to the debuff slots so you can see what he is vulnerable to . You will then have about 45 seconds to pull Ossirian to the next crystal before his debuff runs out and one - shots the Main Tank . The crystal has a slight casting time , so don ' t wait until the last second . It ' s generally best to click it between 10 – 15 seconds left ( 30 – 35 seconds elapsed ) on his debuff . Generally , Ossirian will reach the next crystal in 15 – 20 seconds , giving approximately 15 seconds to DPS before moving to the next crystal . Due to the fact that the MT and OT have relatively little aggro at the start , since both alternate tanking , it is advised the raid does absolutely no DPS until after the 2nd crystal , and then only white damage until after the third . Then they can begin to open up , but be aware that the tanks have not generated as much threat as usual , and casters will be doing significantly increased damage when he is vulnerable to their school of magic . Kiting Ossirian . The mounted player , with a raid icon on them , will be responsible finding the locations of spawned crystals . This information should be relayed to the crystal clicker via vent or party chat . The clicker will be responsible for calling out and pinging the map on the next crystal to kite Ossirian to . ( Having the clicker ping the map rather than the scout allows the scout to keep scouting after finding one crystal . ) Once the closest crystal is located , the raid will all move towards it , staying between the MTs and the crystal if possible . Healers especially should try to stay close to the MT , because he can be knocked out of LoS and killed very quickly . When the raid arrives at the crystal , DPS until CT _ Raid gives a 15 second warning , then pop the crystal . Ossirian has an AoE “ Curse of Tongues ” . This curse needs to be removed as soon as possible , especially on the healers , by druids and mages at all times . Generally crystals spawn in a clockwise or counterclockwise manner , and the kite path can be pretty consistent . Some crystals spawn pretty close to each other , so the tank should just get to the next crystal , stay there until the 15 second warning and let the rest of the raid catch up and do damage to Ossirian . See the external links section for a strategy that includes maps of potential crystal spawn locations . Always watch out for tornadoes in and near the kite path . Note that the tank should not position Ossirian directly on top of the crystal , as Ossirian ' s knockback can send the designated clicker flying ( and causing a wipe ) ; rather , tank Ossirian slightly before it . You should have one or two designated players to click the crystals every 40 seconds . Consider that speed abilities like Blink or Travel Form may save the day . To get the timing , you can use a timer addon , a fitting ability cooldown or an ordinary clock . " Fight in the Center " Technique . There is a considerably easier technique for keeping Ossirian near crystals . Assign two ( unmounted ) players , typically hunters using Aspect of the Cheetah druids using Travel Form , or shamans using Ghost Wolf , to patrol the edges of Ossirian ' s courtyard and immediately click on any crystals they find . This will cause the crystals to re - spawn in the center of the courtyard . It should be noted that another crystal spawns by itself in front of the pillar to the right of Ossirian ' s stairway . It can be helpful to place the least valuable member of the raid on this spawn spot for the sole purpose of clicking this crystal when it spawns . Though 3 people will now be out of the main fight , this will almost guarantee all three crystals being ready constantly in the center of the map . The rest of the raid simply fights Ossirian in the center of the courtyard at the crystals , which will be plentiful there . Without the requirement to find and move so far to the next crystal , it takes only half as long to kill Ossirian , healing is a lot easier , and there is much less risk of a wipe due to being unable to find a crystal in time . The main risk is then due to a DPS character stealing aggro from Ossirian , as he will be doing considerably more damage . The increased damage cannot be understated ; the crystal debuff and stationary nature of this method can make it very easy for a DPS caster to overaggro in this fight . At one time it was believed tornadoes could come into the center of the courtyard , but after testing this has been proved as inaccurate . There are two tornadoes that come close to the crystals on the edges of the courtyard , but they do not enter the courtyard itself . Warning : If the tanks are too close to the crystal when Ossirian does his knockback it can kick them into the tornadoes . The way to avoid this is to simply hold Ossirian close enough to the crystal that a knockback will result in the melee landing right next to the crystal . Blizzard has taken no stance on if this tactic is an exploit or not . Offtank . The reason why an OT might be needed is because Ossirian casts a debuff on the person highest on his aggro list . If you get caught in a tornado , you are caught in a whirlwind for 8 seconds , and you temporarily lose aggro . The effect can not be dispelled , so when the MT gets caught in the tornado , Ossirian will aggro someone else , which is why an OT is needed , to catch aggro and continue moving Ossirian towards the next crystal . Depending on levels of threat , Ossirian may or may not return to the MT after the whirlwind debuff ends , and he definitely will if he casts it on the OT . Because of this , the two tanks need to always try to stay close together , and be between Ossirian and the next crystal . When things go badly , for example , the OT is stunned right next the crystal and Ossirian runs after the MT who is 30 yards away , the OT can use his Insignia of the Horde / Alliance to break the stun effect and regain aggro immediately . High Nature Resistance can prevent the stun debuff . A second offtank is not a bad idea , either , because it is very possible that one of the maint two tanks could go down . AoE Knockback . Ossirian ' s other ability of note is his Area of Effect knockback , which deals approximately 1000 nature damage and launches everyone within a sizable distance into the air , landing about 30 yards away . This ability causes most wipes , either due to a tank being knocked out of Line of Sight of the healers , or a tank being knocked away from a crystal and being unable to make it back before Ossirian gains supreme mode . The latter problem can be prevented , for the most part , by having the tanks , once they reach a crystal , to stand with their back to it , so they don ' t get punted too far . It helps for a healer to stay right on top of the MT , so they get punted in the same direction as he does all the time . Tanks need to be experienced at switching to berserker stance and intercepting , or using bloodrage , then intercepting , and it also helps for tanks to have swiftness potions at hand , should things go badly . Killing Ossirian . Ossirian has about 500 , 000 hit points , and dies relatively quickly due to the vulnerabilities that he gains from the crystals . The fight still usually lasts over six minutes using the scout - and - kite technique , because the raid cannot do damage all the time . After the first few crystals , casters will want to do moderate DPS , and save the bulk of their damage for school vulnerabilities that they can take advantage of . Melee classes can do effective DPS , but be prepared to back out and bandage if you get low on health . Decursers , if they use decursive , should set it to ignore physical damage classes . Usually it will take a few attempts to get everyone to figure out what ' s going on , especially the tanks . The rhythm of the fight can be difficult to develop , but once it gets going , taking down Ossirian is pretty straightforward , although luck with crystal placement does play a big part in this fight . Level 70 . This boss is still quite difficult at level 70 and although a decently geared tank will only be taking 3 - 4k hits during this fight , allowing the raid to simply heal through his Supreme Mode , it is still worth dragging him to crystals to up DPS . Have a good offtank if you decide to dps him straight out or he * will * one - shot clothies while in supreme mode and the MT is under the effect of enveloping winds . Level 80 . Soloing Ossirian at level 80 is possible with a Naxx geared Unholy / Tank specced Death Knight or Protection Paladin . However , it should be noted that after wiping some of the crystals might remain in the zone and will not debuff Ossirian when activated . They must be despawned before the encounter is restarted . This bug is perhaps related to the Shadow of Death ability that allows Death Knights to respawn as ghouls after their death . Soloing Ossirian is also possible with a feral druid in decent raid tank gear , as well as a fairly well geared protection paladin . It has also been demonstrated that a hunter can solo Ossirian . Warlocks may have a tougher time due to the lack of track elemental . Soloing him just takes a little time , but can be done with many classes . Myth . Also referred to as a horusath , a reference to his appearance which resembles the Egyptian god Harakhty ( " Horus of the Horizon " ) , one of the sun gods . The name " Ossirian " is a tribute to , god of death and rebirth .
