Halfus Wyrmbreaker Halfus Wyrmbreaker is the first boss encounter in Bastion of Twilight . Drake Mechanics . When you enter the room , you will see Halfus Wyrmbreaker , a Proto - Behemoth , 4 friendly drakes , and a cage with friendly whelps in it ( which counts as the 5th drake ) . On normal mode of the encounter , 2 of the 5 drakes will be lying on the ground at a quarter life with the debuff Unresponsive on them while the remaining 3 will be standing and at full life . The 3 standing drakes are the ones that will determine which abilities Halfus and the Proto - Behemoth will have for that raid week ( soft resets do not change which 3 you get ) and will change only after the resets on Tuesdays . After Halfus has been engaged , raid members may release the drakes in any order and / or simultaneously by " talking " to them ( there is a 1 . 5 second cast associated with it ) . The drake or whelps will turn hostile and then be tanked . The drakes themselves have no special abilities or attacks ( like cleaves , breaths , tail whips , etc . ) Each drake provides a passive buff to Halfus or the Proto - behemoth that will last for the entire fight regardless if that drake is active , hostile or killed . These are the abilities in brown below . On release , they will apply a unique debuff to Halfus or the Proto - Behemoth . These bonuses are shown in green . Whenever a drake ( or all whelps ) die ( s ) Halfus receives the Dragon ' s Vengeance debuff which increases the damage Halfus takes by 100 % from all sources , which stacks for each drake / whelps killed . Storm Rider The Time Warden The Slate Dragon Nether Scion Orphaned Emerald Whelp Recommended Priority : " Tl ; dr - Storm > Time > Emerald > Nether > = Slate " Strategy . The strategy for this fight revolves around setting drakes and the whelps free and killing them to activate several debuffs on Halfus , and then Burning down a significantly weakened Halfus . Your strategy will depend on which drakes are active . The whelps have the same function as the drakes , in that they will either be available to kill , or you will have 3 drakes up . No matter which three of the five drake / whelps are active for the fight , it is always recommended to kill at least two drakes . In the final stages of the fight , Halfus will cast Furious Roar which stuns the entire raid and does damage . This stun , combined with some of the other abilities , can wipe the raid if the drakes have not been killed . Killing drakes takes time , but the act of releasing them also increases Halfus ' damage taken by 100 % per drake . Whelps are best tanked near their cage . A tank must be ready to use AE abilities to aggro them , and then the raid can AE DPS them down . Detailed combinations : Heroic Mode Changes . Heroic Mode Halfus has all 5 drakes active instead of just 3 granting Halfus the the Proto - behemoth with all of their abilies . The abilities hit for more and Halfus has significantly more life with the same 6 minute enrage . However with all 5 drakes being active , it is possible to debuff Halfus to take an additional 500 % more damage when all 5 drakes have been released instead of the normal 300 % in normal mode when all 3 drakes have been released .
