Twilight Ascendant Council < onlyinclude > < / onlyinclude > Twilight Ascendant Council ( sometimes just called " Twilight Ascendants " ) is a " council " boss encounter of Bastion of Twilight , a raid of " " . Pre - encounter trash . Before you enter the room of the Twilight Ascendants , the room will be full of elementals running all over the place . Dealing with them might be hard , the trick is to pull 2 mobs at the time ; Fire + Water or Electricity + Arcane . Make sure the water adds are interrupted . Doing it this way the fire and water or electricity and arcane will make sure the shields disappear . Encounter . The ascendants include : At phase 3 of fight , they combine into : They are Twilight ' s Hammer members who have ascended and become elementals . Engage the bosses with split teams of DPS . The DPS can be dedicated at first to bringing their specified bosses to low hp but at around 30 % on either boss , switch and slow DPS to get them evenly to 25 % or lower . When Ignacious casts Aegis of Flame , all DPS must switch to him and burn his shield down or the raid will take enormous AOE damage until wiped . Feludius casts a waterbomb technique that hits specified areas and give players the debuff Waterlogged . Waterlogged reduces your movement speed , but more importantly sets you up to be killed by Glaciate . If a player is hit by Glaciate and Waterlogged , they will trigger Frozen Blood and be a strain on the healers . When either boss reaches 25 % , Phase Two begins . The rules of the first encounter still apply to these two bosses . Arion and Terrestra both cast a powerful spell that can be avoided but will kill anyone who doesn ' t handle the mechanics correctly . Cyclones and Gravity Wells will spawn across the room when engaging the bosses . As soon as the fight begins , wait for a Cyclone to be cast and run to it as soon as possible to gain the Levitate buff . Terrestra will always cast quake first and it will deal enormous damage to any players who aren ' t currently levitated by the cyclone buff . As soon as quake is cast , run to a nearby gravity well . Gravity Wells cause you to be grounded for when Arion casts Thundershock , the aerial version of Quake , striking anyone with the levitate buff . These bosses will never cast out of order and you have ample time to get the needed buff . Rinse and Repeat until one or both hit 25 % health . The Elementium Monstrosity will have the combined HP of all four bosses in this phase . This is why lowering the HP of the prior encounters is extremely important . Save all major cooldowns for this phase as it is a DPS check . The boss will spawn over a pool of ice and must be kited out of it or it will expand similar to defile . Range dps must spread to avoid excess damage from Electric Instability . The boss will also cast Lava Seed that will drop all over the floor around the raid and must be avoided to save heals for Gravity Crush and tanks . Gravity Crush will do extreme damage to one raid member , heals must be focused on them for survival . Electric Instability will hit the whole raid and increase in damage over time , making this fight a DPS race from the second the phase starts . Manage to down the boss quickly before losing your raid and you ' ll have defeated the Twilight Ascendants .
