Raid System: Rumble
This is a new raid system in Lost Ark. Whenever the boss is staggered, all players are transported to another map. There will be 3 bars replacing the boss' HP. The goal is to keep DPSing until the party hits each of the bars. During this time, all players get a 50% damage buff. For the first bar, you have 10 seconds of free DPS to complete the first bar. After each bar is completed, the boss will do 1 random JG pattern. Depending on how many players succeed the JG, that is how much free DPS time you get for the next bar. Successful JGs also provide a 50% CD reduction. Should you fail to complete the bar in time, you get kicked back out onto the normal map. This leads to alot of DPS loss. Each subsequent bar also has a higher DPS check requirement, so it's important to use Dark Grenades and Atros should you succeed the JG patterns.
Below is the free DPS time allotted should the players succeed the JG patterns:
- 4 JG: Perfect (+10s)
- 3 JG: Excellent (+6s)
- 2 JG: Great (+4s)
- 1 JG: Good (+2s)
- 0 JG: Miss (0s)
Now let's go over the different JG variations the boss will do in this phase.
- Fast Hammer: She spins the hammer and then slams the ground. Press G as soon as you see the spin.
- Slow Hammer: She holds the hammer up high in the air for 3 seconds before slamming the ground. Press G 3 seconds after you see the yellow flash.
- Wheel: She spins a wheel and when the wheel is about to stop spinning, press G.
- Broom: She levitates a broom with both hands in the air. The broom then flips and slams the ground. Press G as soon as the broom flips.
- Scythe: She spins a scythe with one hand and instantly throws it. As soon as you see the scythe appearing, Press G.
There are certain JG and counter patterns that help with the stagger bar allowing you to access Rumble quicker. Please see the Rumble stagger patterns below for a full list.
x270 Saws and Spikes
Spikes will appear on the field, column by column. It can start from either the left or right side. One row will always be safe. At the same time, saws will appear from the top and damage any players hit by it. The saws do about $140k dmg. The boss will target one player and shoot a laser that damages and pushes the target away. The boss will always backstep from the player before shooting the laser. Players could aggro her to the safe row to allow for more DPS opportunity.
In Nightmare mode, a bomb will spawn on top of another player's head. Any other players that are within the vicinity of the bomb when it explodes will get damaged and pushed away. The player with the bomb should stay for away from the rest of the players, so it doesn't impact DPS opportunity and to avoid accidents.
This mech happens every minute hereafter.
x240 4 Just Guards
The boss will teleport to the centre and do a series of JG patterns. Similar to the 270 bar mech, in Nightmare mode, a bomb will spawn on a player's head.
The mechanic will happen in the 3x3 square in the middle. Safe spots will first appear in the top left/bottom right or bottom left/top right and will move up or down depending on where the safe spots first appeared. The first 3 safe spots will always go up or down and not left or right. The last safe spot will always be at the 6 o'clock position. For NM/HM, all players can gather on either side and move to the safe spots accordingly. However, for Nightmare mode, all players will start on the left side for the first safe spot. Afterwards, the player with the bomb moves to the right side for the safe spot to avoid blowing people up. After the first 3 safe spots, all players will gather at the bottom for the last safe spot. Before moving to the next safe spot, the boss will do a JG pattern. This must be guarded or else you will take damage and be stunned and most likely die from getting hit by multiple spikes. This stun is cleansable, so make sure to use your Sacred Charm or purify skills to cleanse any teammates stunned by the attack. The boss has 3 different JG patterns and she will cycle through these 3 patterns in a random order. We will go over them below.
- The hammer will start in an upright position and she will immediately slam the hammer on the ground.
- The hammer will start in an upright position and move down to do a fake slam before swinging the hammer back and slamming it on the ground.
- The hammer will start in an upright position and she will twirl the hammer in a circle before swinging the hammer back and slamming it on the ground.
The last JG at 6 o'clock will always be a charged up JG pattern. Count one second before pressing G.
x195 Wall and Floor Spikes
After the cutscene, the view changes and players will have to dodge the spike traps from the side as well as the ones that spawn from the ground. The squares where spikes will appear will have a yellow border around it, while the spike traps on the sides will shake a little before moving together. The side spike traps will damage and airborne the player, but the spikes from the ground is an instant kill. In Nightmare mode, one player will have a bomb on top of a player's head. As such, for nightmare mode only, the map will be split in half. The player with the bomb will dodge the traps on the top side of the map and the rest of the players will dodge the traps on the bottom side of the map.
x175 5 Bomb Explosion
5 large bombs will spawn on the map. Each of these bombs will create a plus shape explosion. The goal is to find the safe spot that the bombs will not hit. In nightmare mode, one player will have a bomb above their head. That player must move to a different safe spot. There will always be more than 1 safe spot. In NM exclusively, the bomb explosions will have telegraphs.
x105 Get to the Safe Spot
The boss teleports to the middle and a bomb will spawn on all player's heads. At the same time, all tiles except for the corner tiles will be lit up yellow. Those corners will be the initial safe spots. All other tiles will spawn spikes after a few seconds. After the bomb explodes, the tile that the player is standing on will glow yellow and after 2 seconds, spikes will spawn which deals massive DoT damage to players caught by the spikes. These spikes will stay on the field until the mech is over. At the same time, a tile will be glowing white. That will be the safe spot at the end of the mech. Halfway through the mech, there will also be 2 big bombs that detonate in a plus explosion. There will be 2 big bombs in Nightmare mode, 1 in HM, and none in NM. The goal of the mech is for all players to slowly move towards the white tile. There will also be 2 white tiles in NM/HM, but only 1 white tile in Nightmare mode.
While there are multiple ways to pass the mech, the easiest way is to move 2 by 2. Split up into parties of 2. Each group will start on either corner of the map. At the start, the 2 players will stay slightly apart to not get knocked by the bomb. Once the bomb has exploded, quickly spacebar into the safe spot. The goal is to move together so that only one tile from each group spawns spikes. When the 2 large bombs are about to detonate, all players will use hyper awaken to the middle. This allows the party to do damage to the boss plus move closer to the final safe spot. When the white tile turns green, all players must dash into that tile to avoid getting one shot by the boss.
Supports should also use their Hyper Awakening at the start of this mech.
x90 5 Iron Maidens
The field becomes smaller and the boss will hop on her broom. After a few seconds, 5 iron maidens will appear and shoot out a flamethrower attack in the direction it's facing. All players must move to the safe spot. In normal mode, there will be red line telegraphs to mark where the flames will shoot. However, there are no telegraphs in hard mode or nightmare mode. In addition, in nightmare mode, 1 player will have a bomb above their head, so that player will need to find a safe spot away from the other players. After successfully moving to the safe spot, the boss will teleport to a player and perform a counter. If this counter fails, the boss will knock everyone to the edge where there are spikes which deals massive DoT.
Normal Patterns
In this section, we will go over the normal patterns for Serca. We'll start off with the Stagger patterns that help reduce the stagger bar for Rumble.
Rumble Stagger Patterns
The boss will fly up in the air and flash yellow to do a JG. Press G when she flashes yellow. If JG fails, then any players that failed will get sent to the Iron Maiden and the remainder of the players must stagger her to free the trapped players.
Serca will jump back and do a 180 degree turn before throwing down an large nail to grab people. If someone is grabbed, then the boss will require a counter to save the player. However, if nobody is grabbed, then players will need to do a just guard when Serca slams the hammer on the nail. After just guarding, thick red line telegraphs will appear. Dodge the red line telegraphs.
Serca floats in the air and arrows will appear on the map. Dodge all the arrows once it fires. Then Serca will disappear and you will need to do a slow JG which will be indicated by a circular yellow telegraph.
Serca throws her broom in the air. When it lands, you will need to JG. It will be indicated by a large circular yellow telegraph. After succeeding the JG, stay close to her to avoid the damage from the broom.
Serca will target a player and fly to the player's backside and require a counter.
Serca flies and summons beam wall that damages and knocks back anyone within the wall similar to Kazeros. After summoning the beam wall, she requires a fast JG. Those caught in the beam wall won't be able to perform the JG as they will be stuck in the knock back.
One Shot Patterns
These are one shot patterns that need to be avoided at all costs. Normal and hard will have telegraphs, but nightmare will not, so you will need to remember where the attack is going to be.
Serca will throw a spinning scythe in front of her before jumping to grab her scythe. She will then do a 270 degree slash behind her. Go to where the spinning scythe was to avoid the 270 degree slash.
Serca will have a red aura and then a red shadow behind her will charge up a scythe swing that will attack all sides except the side where the scythe is pointing at. The safe spot is a 90 degree angle. Be sure to stay close to her side where the scythe is pointing at.
Serca will have a red aura and hold up her scythe. She will then turn to an aggro and slice down once. She then disappears and does a one shot slice. If anybody is hit by the first slice, that player becomes airborne and Serca targets that player for a guaranteed one shot death. If she doesn't hit anyone on the first slice, she will then turn to a different aggro to do the one shot slice. Supports can DR the first slice to guarantee the one shot slice to target them instead of another DPS. This can allow for more DPS uptime.. Supports will also need to dodge the one shot slice.
Other Normal Patterns
A circle will surround Serca and she will flash blue for a counter. Don't counter her yet. Wait until the inner circle explodes before countering. If you counter before the inner circle explodes, the resulting attack will do alot of damage to everyone inside. If you counter after the inner circle explodes, then the inside is a safe spot.
Serca spins her broom turning it into a wheel. She then slams the wheel on the ground in front of her. Anybody caught will be grabbed and then she backsteps and fires a few bullets and one shotgun shot that deals massive damage. If no one is caught, she just attacks the front.
Serca will spawn a wheel and throw it in front of her. After travelling some distance, the wheels multiplies into 7 - 3 on each side and 1 in front of her. The wheels then travel back towards her dealing damage along the way. She then grabs the wheel in front of her and slams the wheel behind her. When you see her instantly spawn the wheel and throw it, stick to her back side.
Serca will spin her broom a few times before slamming it on the ground. This is outside safe. Afterwards, she slams the ground 3 more times which result in line explosions. The first safe spot is always her back and then it alternates.
Serca will spin her broom once in a small circle radius and slams the ground. This is an outside safe to inside safe pattern.
Serca will spin her broom once in a large circle radius and slams the ground. This is an inside safe to outside safe pattern.
This pattern only appears after she reaches 90 bars. Traps will start spawning from any of the corners and protrude out one column/row at a time. Serca will also lock onto a player to do a barrage of laser beam shots. Aim the laser beam at one location and then spacebar to where the spikes were earlier.
Serca spawns spike traps that kills anyone caught in it. Be sure to stand in the safe spot while DPSing.
This pattern only appears when she's backed to an edge. She'll try to free herself and depending on her HP, she'll do a different pattern. After 175 bars, she'll dash back and arrow barrage her back side. After 90 bars, she'll dash back, slam her back and then shoot her arrow barrage.
This is an intro pattern. Multiple brooms will spawn on the ground dealing damage along the way. It then returns sweeping in the column next to it.
Serca will fly up high and then fly down, damage anyone along the way and when she lands, it will result in a donut explosion.
Serca rides on a wheel and flies up. Then a large wheel will drop. It does massive damage to anyone hit. The safe spots are where there's no shadow.
Serca hops forward and then splits into two. The one with the golden broom is the real one. Stick to her to dodge the resulting donut explosion.
Serca spins two wheels on each side damaging any players caught. Then line telegraphs will appear. Just stay at her front or back to dodge the pattern and for DPS opportunity.
Serca dashes to a player and claps a player with her wheels. This happens two times.
Serca spins while chasing a target. At the same time, her spin also damages her surroundings. While she's spinning, players should not DPS as the spin does a lot of damage. After she finishes spinning, she's stunned for a brief moment. This is a big DPS opportunity.
Serca hops to a target. Stay close to her after she hops to dodge the resulting donut explosions.
Serca aggros to a target and starts pulling in pins. She then shoots them back out on the same target. Supports can use DR as the pins are being pulled in to lock in the aggro for more DPS opportunity.
Serca aggros a target and pins forming a star shape appears. The pins then shoot out dealing massive damage to any players hit. Afterwards, the pin will shoot out for a second time. Be sure to dodge both.
Serca hits the front and then back simultaneously and then strikes again at the same time.
Serca summons a cauldron that spawns bombs that damage the field. The bombs then muliply a few times on the field exploding on contact. She then targets an aggro to shoot the cauldron.
