World of Warcraft – Operation: Floodgate Beginner Guide

Publication date : 2025-11-26

Operation: Floodgate is the last dungeon in the Mythic+ rotation of the third season. It is challenging—requiring good teamwork, understanding of game mechanics, and some experience in Mythic+ dungeons. It is important to destroy five weapon stockpiles in the dungeon.

First area

First wave of trash

In the first area, many enemies will come at you. Important dangers:

An "Explorer Werewolf" uses a laser beam that is always aimed at a player and creates fire rings under its feet. This mob takes priority.
The "Ripping King Robot" can shoot fire beams from the front and spin. Additionally, it places gears under each player that must be avoided.
A tiny robot often goes unnoticed. It selects a target, turns around, and causes great damage. You can control or disrupt crowds.

After this wave, the first of five weapon stockpiles is to be destroyed.

Second Trash Wave

After that comes the second wave. Important mobs:

An architect stands on a scaffold, which reduces damage. First, the scaffolding must be destroyed before the body can be attacked. A player is knocked down by each attack, which is dangerous with many ground effects.
A diver throws bombs and uses a harpoon to catch players. You have to stop him.

After you have defeated the enemies, you can decide whether to fight Boss 1 or Boss 2 first and then destroy the second stockpile.

Boss 1 – Big M.O.M.M.A.

In the room, there are four additional Mechadrones.

Mechanics:

The Mechadrones attack unexpectedly and must be stopped. They use the attack "Maximum Distortion," which deals a lot of damage.
Big M.O.M.M.A. attacks a player with "Sonic Boom." The player must move away to avoid damage and negative effects.

Strategy:

First, focus on the Mechadrones. When all four players from the team are defeated, the "Jumpstart" phase begins. The group takes heavy damage every 1.5 seconds for 12 seconds, while the boss takes 200% more damage. Use healing and damage cooldowns at the right time.
After that, electric zones form under the boss, which are referred to as "Excessive Electrification." Move the tanks so that the group does not stay in these areas. - The pattern repeats itself over and over again. Adds to activate electro zones.

After you have killed someone, you should destroy the fourth weapon stockpile

Boss 2 – Demolition Duo

Two bosses at once: Keeza Quickfuse and Bront.

Mechanics:

When one of the bosses dies, the other becomes stronger and deals more damage. That's called the "Divided Duo" enrage. Destroy something at the same time.
Keeza is a fan of B.B.B.F.G. in AoE and uses "Quick Shot" on random players. Keeza places bombs ("Big Bada Boom") with a 30-second timer in the arena. When they explode, they cause significant damage to many enemies and add additional damage over time. With "Kinetic Explosive Gel," you can trigger small explosions to remove bombs.
Bronts executes the "Barreling Charge" with bombs. Bront has a frontal attack called "Wallop" (tank-buster) and also a charge.

Strategy:

Distribute the damage evenly between both bosses.
The bombs should be placed so that Bront's attack hits many enemies. Use dispels carefully.
Tanks turn to defend themselves and stay close together to attack better.
The healer is ready for many injuries from bombs—explosion fail.

After you have killed someone, you should destroy the third weapon stockpile.

Trash before Boss 3

In the next area, the elite opponent named "Twister" inflicts significant area damage over time with his attack, which is stronger than that of the first boss. Then destroy the last stockpile on the fifth weapon stockpile. Go down to the next weapon stockpile.
Two packs of algae mobs: He heals himself with "Rejuvenation" and should be interrupted. Other mobs use group attacks and should be stopped with CC/interrupts.

After that, activate the bomb and start with Boss 3.

Boss 3 – Swampface

Mechanics:

In the game "Pull," four players are paired up with "Razorchoke Vines" (2 pairs). The two must stay close to each other; otherwise, they will be drawn in and die.
A "mudslide" is a large attack on a player that should be avoided.
Circles explode one after the other, creating waves that spread out. Watch out for the tank that absorbs damage and takes healing, called "Sludge Claws."

Strategy:

What one wants to do to achieve a goal.
Before starting, pairs should discuss where they are going and which path they will take.
The tank reduces the damage from Sludge Claws; the healer carefully uses their abilities on cooldown.
In the fight against the boss, deal a lot of damage and dodge attacks.

After you have defeated someone, go to the final area.

Final Area & Boss 4 – Geezle Gigazap

Trash:

An electrician can stop "Lightning Bolt" and remove the "Overcharge" DoT.
A jump starter creates electric puddles that should be avoided.

Mechanics:

Start and whenever the energy is full. After resetting: Activate "Turbo Charge" for about 10 seconds. In the meantime, a lot of damage is dealt every secon and line attacks are executed every 2 seconds. The healer is ready!
After that, circles called "Dam Rubble" will form, which will become "Dam Water." Necessary for the upcoming repair.
In "Leaping Sparks," five sparks fixate on the players and jump around. The players must be pulled through the dam water. If a puddle is used, it becomes "Shock Water" and is dangerous for players.
"Gigazap" randomly damages two players with an area attack—avoid water.
The tank buster "Thunder Punch" causes physical damage, nature damage over time, and knockback in the water, which leads to death.

Strategy:

Position the boss so that his back is to the console to prevent him from being knocked back and falling into the abyss or the water.
The team marks clean puddles, waits for the Sparks phase, and then uses each puddle for kiting. It is very important to communicate with each other.
The healer is in use during Turbo Charge.
Avoid water mechanics. After the kill: Success! The dungeon was successfully completed.

Tips

Eliminate trash and clear weapon stockpiles to defeat the bosses one by one.
Interruptions, placement, water/puddle mechanics, and mechanics are particularly important.
Tanks position themselves and mitigate damage, DPS execute mechanics and deal damage, and healers pay attention to major damage moments.
In Mythic+, it's important to be quick and execute well.
