Disclaimer: In this guide, we will only focus on the important core mechanics and attacks of the hard mode bosses. The normal mode has similar but simpler mechanics compared to the hard mode.
This guide assumes that you are familiar with the recommended Raid Build for your class.
First Boss
Every time you incapacitate the boss by using Stagger Damage he gets an stacking attack buff. Once he gets the third stack, he deals an insane amount of damage and starts to use 1 shot skills. To prevent this, make sure to remove Stagger runes attached to your skills and avoid using skills with high Stagger Damage. Keep the buff at 2 or below. Upon reaching 2 stacks, use the Grab mechanic to reduce the stack.
Special Interactions & Patterns
Grab
After every 2nd Cardinal Flail Strike the boss uses this mechanic and attempts to grab someone in front him. Make sure that a player is always in front of the boss at the end of Cardinal Flail Strike. Once a player gets grabbed, the other 3 need to use skills and combat items with the Stagger Damage affix to incapacitate the boss. As a positive side effect, the boss loses one stack of his attack buff.
General Patterns
Cardinal Flail Strike
The boss swings the flail above his head and smashes it 4 times to the ground, striking each of the cardinal direction once. He finishes his combo with a high damage attack in front of him. Immediately after it, the Grab mechanic can follow.
The spots struck by the flail will be surrounded by a dark flame. If you come in contact with it, you get a debuff which increases the damage you take and also reduces the Stagger Damage you deal to the boss. This debuff can be useful for classes with high Stagger Damage and helps to avoid incapacitating the boss too fast.
Roar
The boss roars shortly before he swings his flail to hit everyone around him, dealing high damage. Make sure to run away as soon as you see the roar animation!
Dark Orb
The boss summons a dark orb that chases after a player. On contact, it explodes and deals damage to everyone nearby. If you are the target, make sure to run away from your teammates before you trigger the explosion.
Second Boss
This boss has a variety of skills which deal high damage in a huge area. On top of this he does faint/cheat attacks and changes the battle area upon reaching the 16th Hp bar (Phase 2) and 6th HP bar (Phase 3).
The boss heals over time if he is not affected by any damage over time (DoT) effects. Bleed is a great way to prevent the regeneration. If no one i the party has this rune make sure to use skills that deal DoT damage by debuffing the boss with various effects like burn or poison.
Special Interactions & Patterns
Love Bondage
An attack that becomes available in Phase 2. The boss imprisons 3 players and the remaining player needs to quickly liberate them before an explosion occurs below them. This can be done by using mult-hit skills, the damage of the skills doesn't matter. Flame Grenade is a great Combat Item which can aid the player to free the imprisoned ones faster.
Shortly after succeeding the first part of this mechanic, the player who wasn't imprisoned previously will be the one imprisoned this time. The remaining players can liberate the player this time by using skills with high damage.
General Patterns
Cheat
Two overlapping blue telegraphs slowly appear below the boss. One in the form of a circle and the other one is cone-shaped targeting an area in front of the boss. Only one of these 2 will actually deal damage and the other one is a faint. The telegraph which disappears first is the faint.
Black and Red Totems
Disco balls spawn at the edge of the battle area and start rolling towards a player. Once they get close to a player, they transform into either a black or red totem. The black totem explodes after a while and the red totem drains the mana or energy of nearby players. These totems can be easily destroyed, so make sure to destroy themif they are close to you.
Mirror Balls
The boss teleports to the center of the battle area and starts to spawn multiple waves of mirror balls. Make sure to destroy the spawning balls as fast as possible. If there are too many of those on the battle area, the boss can use an attack to wipe the party. Preventing this is easily done by spreading out and covering a bigger area.
Shortly after starting this mechanic the boss drops a few exploding bombs on you which can be easily dodged. At the end of this mechanic, the boss is incapacitated for a short time. Use this opportunity to deal uninterrupted damage.
Mass Bombardment
The boss remains stationary while standing on a ball. If you see this, spread out immediately. Shortly afterwards multiple waves of exploding balls drop above each player's head. Don't panic, simply take one step every time after an explosion occurs. By doing so, you can easily avoid getting hit by the explosions. At the end of this mechanic the boss is incapacitated for a short time, use this opportunity to deal uninterrupted damage.
The Chase
The boss runs in slow motion towards a player before he jumps on a ball and start chasing that player. If you are the targeted player, keep running away from the boss until he trips and falls over and use this opportunity to deal uninterrupted damage. If the boss touches the player or the player touches the puddle left behind by the boss, they takes damage.
Kicking Balls
The boss targets a player and kicks a ball towards them in short intervals. The ball ricochets and changes its direction frequently, making it hard to dodge it. On hit, it deals heavy damage so try your best to dodge it. If you are targeted, make sure to turn the boss away from your teammates and towards a wall.
Key Input
Everyone gets stunned at the start of this mechanic. A key input sequence appears on everyone's screen. You have to type the keys from left to right in correct order. After typing the correct order, you are able to move out of the one shot AoE which appears below each player. If you make any mistakes and press the wrong key, the sequence resets and you might not be able to dodge out of the AoE in time.
