Skarvald the Constructor Skarvald the Constructor is a Vrykul boss in the Utgarde Keep . It is likely he is the one building the tunnel to Gjalerbron . He is also accompanied by Dalronn the Controller , a necromancer . Both of them will fight at the same time when aggroed . Abilities . Skarvald the Constructor : Health : 96 , 100 HP Normal . Strategy . Kill Order . One school of thought is that they should both die at roughly the same time . This strategy involves DPSing Skarvald down to 10 % , kill Dalronn , and then finish off Skarvald . This is because Skarvald will randomly charge players , and when his spirit spawns it will do the same , usually towards the healer . Since the spirit has no aggro table , he may stay on the healer until the fight finishes . Another is that with his casting times Dalronn is by far the easier of the pair to heal through and really doesn ' t have an aggro table anyway . This strategy involves having the tank build aggro on both bosses , but all DPS goes onto Dalronn . Once he dies you ignore his spirit and focus all attention on Skarvald . There are no standard strategies that involve killing Skarvald first , as doing so is very likely to result in a wipe . Positioning and Distance . One way to kill the pair is to position the entire group inside Skarvald ' s minimum intercept range . This eliminates the complications introduced by his charging and turns the fight into a standard tank and spank . The other way is to tank the bosses right next to each other so the melee cannot be intercepted , but place the ranged DPS and healers as far away as possible . When Skarvald intercepts one of the ranged characters he will immediately re - aggro the tank ( assuming the tank is top threat ) and the time he spends running back to the tank is time he won ' t spend causing damage . Heroic Differences . Dalronn . Kill Order . No differences here . Either kill both bosses at roughly the same time , or kill Dalronn first . Don ' t kill Skarvald first ; he deals far too much damage to run around without an aggro table , especially with no minimum range on his intercept . Positioning . With the removal of Skarvald ' s minimum range on his intercept all ranged DPS should stand at range . The one exception is groups made up of one tank , three melee dps , and a healer . Skarvald won ' t charge targets in melee range ( he ' ll punch them in the face instead ) so in this kind of group makeup Skarvald will default to the healer every intercept , usually killing the healer on the second or third intercept . In this case even the healer needs to stay in or near Skarvald ' s melee range to avoid getting gibed . Adds . Dalronn ' s summoned skeletons tend to aggro healers like most summoned adds do . However , they only have 10k hp and are vulnerable to every form of CC known ( assuming said CC will work on undead ) . In general the DPS can handle the adds so long as they " all " attack the adds . One person by themselves can get overwhelmed as the adds do hit harder than normal mobs of their level . If the group has heavy melee dps , it will usually work better if a ranged DPSer grabs the adds from the healer and drags them to the tank . With two bosses most melee DPS will be going pretty heavy on the AoE attacks anyway . DPS Healers
