In this phase, you will be fighting 4 dragon BAMs that you are most likely already familiar with from other instances/zones of TERA. Their attack patterns are identical to that of their previous iterations from other instances, with a few mechanics added on.

Dragon Aura: Each BAM has a colored zone around it, in which you and your raid members will be fighting inside simultaneously. It is necessary for your raid to be split into 4 parties, each taking on one designated BAM. If any BAM is left without any players alive inside the zone, it will begin to regenerate HP massively, along with the 3 other BAMs. This means it is necessary for at least one member in each party to be alive in order to not trigger this mechanic. During the fight, anyone is free to move across the zones from one to another, but have only 5 seconds to do so. Standing on ground that is not a zone for more than 5 seconds will damage you for around 10% maximum HP per second.

Tenfold Curse: Every 15 seconds inside a zone, you will receive a stack of debuff corresponding to the color. If anyone acquires 10 stacks, they will instantly be killed and cannot be resurrected. You do not gain stacks while dead. Terradrax’s Tenfold Curse has a yellow icon, Umbradrax’s Tenfold Curse has a dark-red icon, Ignidrax’s Tenfold Curse has a orange icon, and Aquadrax’s Tenfold Curse has a white icon.

Summoning Ritual: Every 8-9 stacks (~2minutes), all four BAMs will undergo a Shield Phase in order to summon Vergos. If any BAM is left with an unbroken shield after their mechanic ends, it will result in a full raid wipe. After you have successfully passed this mechanic, everyone should switch to another color BAM in order to not die from 10 stacks of debuff. This also means that your party will be rotating through the BAMs at maximum 4 times. On the 5th rotation, you will be back to your starting zone and will already be at 8 or 9 stacks, basically meaning a wipe. So it is advised that with each rotation following a Shield Phase, each party has dealt roughly ~25% of their respective BAM’s HP.

• Terradrax
• Umbradrax
• Ignidrax
• Aquadrax

The easiest of the four, its attack patterns are identical to a Fimbrilisk. Its attack speed is slow, but it hits hard.

Hardened Scales: This mechanic begins with a close range AOE explosion. This AOE indicator is orange, indicating that it can be dodged by i-frames. At the same time, he will also gain a 4 second buff. This buff must be removed using Plague of Exhaustion or Regression by your healers. Since the AOE mechanic and buff mechanics begin at the same time, healers can either choose to remove it before or after dodging the AOE first.

Failure to do so will cover the BAM in a 300-Hit Shield with 90% damage reduction for its duration. Notice I say Hits, not HP. It requires 300 hits to break the shield, regardless of damage, so it is advised for everyone to use multi-hit skills to break the shield rather than try to deal maximum DPS.

Earthy Protection: Terradrax will move to the center of the zone. He then will create a wall of rocks around himself. Players must break the rock and stun Terradrax within 10 seconds. Failure to stun will give the BAM a stacking 20% attack speed buff every 2 seconds until stunned (stacks up to 5 times). It is advised to have your party focus 1 rock.

Medium difficulty, identical to a Dracoloth BAM

Evil Thoughts: Umbradrax will periodically spawn Spirits of Agony (in the shape of chibi Melditas) on 0-5 random players. The players affected will be indicated by a purple orb above their heads, just like Pahoegar does in Shadow Sanguinary. After a few seconds, the Spirits will be placed on top of the indicated player’s location. It is advised that the indicated players stack on top of each other in order to make life easier when destroying them later on. These Spirits do not take damage from players. The Spirit-spawn mechanic has a low chance to be followed by an inner or outer ring AOE. Both cannot be i-framed.

These Spirits have an inner ring and outer ring explosion, as well as a laser attack, just like Shadow Sanguinary. They do not one-shot. It is advised to put them far away from the boss, facing the edge of the arena (to lower the chances of the Laser attack killing players fighting other Dragons)
The only way to destroy these totems are by Umbradrax’s Evil Fire.

Evil Fire: After crying out “(Player), burn in my darkness!,” Umbradrax will aim a laser at one random player, then the player must aim the laser at the totems. The laser does a lot of damage in many ticks, but is i-frameable.

Fast with strong attacks. Identical to a Drake BAM

Fire Blast: This mechanic in indicated by Ignidrax being surrounded in flames. At this point in time, every player in this zone will have a meteor above their head that will crash down after a few seconds dealing 60% maximum HP in a small AOE around the player. The damage cannot be i-framed and can overlap, so try to spread apart.

After the meteor has crashed down, it will spawn a Volcano (in the shape of an idle Moloch BAM) below each person’s position for the next few seconds, dealing ticks of damage if you stay on top of the AOE. In addition to damage, if you stay on top of it, the AOE will expand rapidly. After not expanding for a few seconds, they will disappear on their own.

Donut: This mechanic has a 50% chance to immediately follow Volcano Meteors. You must quickly move out of the outer ring of the donut. The damage cannot be i-framed.

Fast, sporadic attacks with many aerial attacks (tough for melee classes). Identical to a Bloodtalon BAM

Cutting Wind: In this mechanic, Aquadrax moves to the center of the zone and flies into the air. After a brief moment, it will come crashing down, pushing every player in this zone to the edge as well as giving them a bleeding debuff. The debuff can be cleansed. This should be treated like Nightmare Lachelith’s pushback or Nightmare Fulminar’s water phase, where the party groups up on the priest or uses a mystic mote (while players closer to the mystic can be cleansed from the mystic itself).

Whirl of Chaos: Aquadrax will begin to be surrounded by wind for a few seconds. Players must stun Aquadrax within this time period. Failure to do so will spawn moving tornadoes (up to 15) inside the zone. These do not do much damage, but knocks the player airborne for a short duration.

This part will test your driving skills, as well as aim.
After the last shield phase has been passed, Vergos will fly up into the air and begin to circle around. Your raid must be positioned near the edge of the map where ballistas are stationed. Vergos will be at 100% HP and the phase will end when he reaches 40% HP.

Destructive Breath: Once your raid DPSs Vergos down to 40%, phase 2 is cleared. Failure to reach 40% by the time the meter hits 100, the entire raid will wipe.

Ballistas: Once the phase has begun, you will be able to repair the ballistas by pressing F. Being inside a ballista gives you three skills: Arrow, Sequential Fire, and Evasive Maneuver.

Arrow (Left Mouse) – Fire an arrow at a target in front of you. After 10 successful hits, you may use Sequential Fire.

Rapid Fire (Right Mouse) – Fire several arrows at a time. The effect is very powerful, always inflicting a critical hit when used successfully.

Evasive Manuever (1, C) – Greatly increases your movement speed.

Fire Waves: Fire walls will stand stationary at the edges of the map. After a brief delay, the walls will begin to move across the map in a linear fashion. It is easy to tell which direction the walls are going to go, but there will be multiple walls on multiple sides of the map criss crossing each other. If you are riding a siege, make sure to dodge the walls first then continue to shoot at Vergos circling around in the air.

Boiling Anger: 10 minutes after 90%, Vergos gains massive Attack Speed, Power, and Endurance. After 50%, Vergos gains a 15% Attack Speed buff until the end of the fight.

Basic Attacks: Exactly the same as Phase 2’s Vergos. Refer to that section.

Dragon’s Eye: Same debuff idea as previous two phases. The timer on debuff stacks are random and mostly dependent on if Vergos is doing a mechanic or not. Stacks will not be acquired during a mechanic, but in between them.

Fire Walls: Same idea as before, fire walls will zoom across the map from time to time. Get out of their way.

roasted.

Volcanoes/”Hakans”: Same idea as before, Vergos’s legs become engulfed in flames and will spawn up to 3 Volcanoes under randomly targeted players on each body part.

Petrification/Meteors: A small meteor will start to enlarge above your head. Once it gets big enough, you will turn to stone and the meteor will strike down in a small AOE around you dealing moderate damage as well as leaving a bleeding debuff. The debuff can be cleansed. It is advised to spread apart before the meteor lands to not overlap any AOE, but quickly gather together to have a priest cleanse everybody in 1 cast. Impact cannot be dodged. If your raid leader predicts a Toroid Heat/Small Bomb or a Blistering Heat/Big Bomb directly afterwards, your healers should not cleanse but rather just heal.

Toroid Heat/Small Bomb: When the floor becomes filled with hints of lava, a small meteor will appear above the head of randomly targeted players in each section of the body. These meteors explode when cleansed or when their duration expires. When exploding, it hits in a huge Donut-AOE around the target, meaning it is safe right near the target and extremely far away, but not in between. Your party should group up before cleansing. If not cleansed, all players inside will die, and the explosion radius is larger.

Celestial Energy: This mechanic occurs up to twice in the fight, the first being at 90% immediately after the pushback. The second occcurance can also be skipped if DPS is fast enough. It is followed by a Destruction Phase (if boss is still above 50%) and a Rock Cage or a Pushback into a Debuff Mechanic (if boss is past 50%).
1 purple orb will spawn behind each location of the body (total 5), and gradually transition to the center of the map. Once destroyed, it will leave an AOE puddle that increases the damage of players inside by 50%. Failure to destroy an orb and it manages to reach the center, the orb will give a damage buff to Vergos.

Destruction/Shield Phase: The first Destruction immediately follows the first Celestial Energy (purple orbs). A shield will cover all 5 parts of Vergos’s body. Break it or wipe. The next shield phase will occur immediately following the second Celestial Energy if the boss is not pushed past 50% after the mechanic. If the boss is pushed past 50%, the next shield phase will occur after the Debuff Mechanic. Every Debuff Mechanic except for the second is followed by a shield phase.

Rock Cage: After the first Destruction, Vergos will do a massive jump and crash down causing a shockwave that will one-shot. Can be i-framed.

After he has landed, he will form a cage of rocks that surrounds him and players caught within the AOE. Players must break through the rocks and hide from the incoming waves of lava. The rocks have a ton of HP, so it is advised to focus 1 rock and escape through there.

After the lava wave has ended, Vergos will come crashing down, breaking all of the remaining rocks. But will also come down with either a donut-aoe or an inner circle-aoe. It is advised to stand roughly where the rocks are and wait to see which AOE it is, then move accordingly. The AOE is not i-frameable.

Igneous Prison: Past 65%, Vergos will do a yellow indicator AOE under it with arrows. Anyone that is caught inside the AOE when it explodes will take moderate fixed damage and turn into a stone statue and receive Suffocating Heat, which kills them if they are trapped a second time. 1 member from each party should be inside the circle in order to get turned into stone. Vergos will fly up into the air and prepare to unleash waves of lava covering the entire map. Hide behind a stone to be safe from the lava. Every stone must be broken right after the lava stops. If not, will result in a wipe. If all stones are destroyed, Vergos will crash back down with an inner circle AOE. It is advised to damage the statues until they are at about 40% HP then wait for the lava wave to end before destroying the statues. Do not use hard hitting skills until the end.

Flame/Dust Debuff Mechanic: At 50%, Vergos will push everybody back to the edge of the map to show his rage, then immediately give everyone a Flame/Dust for preparation for the Debuff Mechanic. From 50% and onwards, Vergos will do this mechanic periodically (notified by “I will drown the world in blood!“. The idea is similar to Phase 3’s Red/Black Debuff Mechanic with Phase 2’s Double Smash Jump attack. Players will receive their designated color debuff as Vergos begins its Double Smash Jump (looking both ways). They have 10 seconds to position themselves to receive the opposite debuff AOE. The first smash will create an impact AOE for Black Debuff (Dust). The second smash will create an impact AOE for Red Debuff (Flame). You MUST get hit with the opposite AOE or else you will explode, dealing large (usually fatal) damage in an area around you. Each impact will deal moderate damage. Refer to Double Smash Jump guide in phase 2 to know which legs hit first. The Jump must also be i-framed. Every debuff mechanic except for the second is followed by a Destruction/Shield Phase.

Blistering Heat/Big Bomb: Past 50%, this mechanic replaces the Toroid Heat mechanic. When this mechanic happens, 1 player from each part of the body will be given a big meteor above their head and a debuff. If there are no players on that body part, the Bomb will go towards a random player. Cleansing the debuff or letting it expire will cause it to explode, dealing heavy fixed damage (45% HP) to everyone in the raid. The goal is to cleanse all meteors before it expires. Leaving 1 meteor at the end to explode on its own is okay too.
Cleansing multiple people with meteors on their head will cause them to explode at the same time (cleansing 2 people will explode for 90% HP damage). It is advised for most raids to cleanse 1 at a time, but raids with experience and competent healers can cleanse 2 at a time (2 legs), then the head last to speed up the process.

Please be aware, this mechanic can immediately follow Living Fire/Meteor mechanic. Be careful when cleansing right after Living Fire/Meteor mechanic, as it might cleanse this mechanic.
