Ichoron Ichoron is a water revenant boss located in Violet Hold . If released , she is one of the first two bosses in the instance . The releases are random , so it is possible that you will not fight her . Ichoron is voiced by Melodee Spevack . Strategy . Ichoron initially comes out with a " Protective Shield " buff with 35 charges that reduces any damage by 99 % . Any attack or spell hit made on Ichoron will remove one charge . When all of the charges are gone , her shield will erupt , costing her 30 % ( 170K on heroic ) of her total health . The eruption will also knock nearby players back , causing damage . She will become untargetable and about ten low - health Ichor Globule s will spawn around the room and move directly toward her . When a Globule reaches her or when there are no Globules left alive , she will become targetable again . This cycle will repeat : 35 Charges , Shield Eruption , Globules summoned . Each Globule that reaches her once she is up will restore a small percentage of HP . Killing the Globules causes them to erupt , dealing damage and knocking back nearby players . When she goes below 25 % health ( which is usually after three cycles ) she will no longer have a shield or summon Globules , but will enrage , hitting hard . This final phase is a simple DPS race . Tanking spots . A good spot to tank Ichoron is up the stairs to the back of the platform by the entrance . This bottlenecks incoming Globules , making them much easier to AoE down and giving them farther to run . Another suitable spot is in the pool which Ichoron emerges from , as no Globules spawn there . These locations also work in combination with the Defense Control Crystal s . Shield phase . During the shield phase Ichoron is practically immune from damage . Tanks will want to focus on abilities that directly give aggro , and not depend on abilities that require damage done to gain aggro . DPS should use quick - hitting attacks , rather than slow attacks with high damage , as what counts in this phase is the number of attacks , not the damage done . Globules phase . When the Globules spawn , they should be stopped from reaching Ichoron . Because they explode when they die , players should avoid being close to them . The Globules die easily , and can either be killed with the Defense Control Crystal s or with DPS . Using the crystals requires some coordination : one player should be assigned to activate a crystal at the right moment , and the other players should be aware that the crystals will be used . Activating a Defense Control Crystal after Ichoron ' s bubble pops will kill all Globules and , if timed right , can stop any from reaching her . The crystals are the key to the Heroic achievement . Note that using a crystal will cause all of the Globules to explode at the same time and can kill players if they are close to a group of Globules . Using DPS requires a good tanking spot and well aimed , preferably ranged , AoE and other quick damage . The advantage is that it does not require any coordination , though players should still keep their distance from the Globules . When Ichoron resurfaces ( because a Globule reached her or all Globules were killed ) , the tank should pick her up again as quickly as possible . Final phase . The final phase is a straightforward tank and spank . Because there is no more shield , tanks can use their normal methods of holding aggro again . Notes . Ichoron ' s Protective Bubble severely reduces tank and DPS aggro , but does not reduce healer aggro . Frost Resistance helps reducing the damage from the attacks by Ichoron . Using a Defense Control Crystal will block the achievement in Heroic . This is no a great drawback , as players will have plenty of opportunities to get this achievement in runs that do not involve Ichoron .
