Operation: Floodgate Dungeon Guide Location, Boss Strategies, and Trash

This guide will be an extensive overview of the dungeon, providing vital information on how to complete it across all difficulties. We will cover all 4 Boss fights, as well as the most notable trash enemies in the dungeon and their important abilities. If you would like to learn about the rest of the dungeons in The War Within Season 2, please see our overviews linked below. Otherwise, without further ado, let us begin!

To summon the Swampface (the third boss of the dungeon) and continue forward, you must destroy the 5/5 Weapons Stockpile Explosion located through the first area of the dungeon.

• Interrupt Darkfuse Hyena Bloodthirsty Cackle.
• Use defensive cooldowns when Darkfuse Bloodwarper is casting Warp Blood. Any spare interrupts should be used for Blood Blast.
• Be aware of Mechadrone Sniper and their Snipe ability, it deals a ton of damage! Any spare kicks should be placed on Trickshot.
• Avoid being hit by Darkfuse Demolitionist's R.P.G.G..
• Darkfuse Inspector will shadow step behind you with Surprise Inspection, make sure to stay close to melee so they don't run away!

• Make sure to defeat the 4 Darkfuse Mechadrones and interrupt Maximum Distortion, before the boss reaches maximum energy and casts Kill-o-Block Barrier.
• Avoid being hit by the Sonic Boom.
• Once you defeat the 4 Darkfuse Mechadrones, the boss will enter intermission via Jumpstart, dealing damage to the whole party and taking 200% increased damage (save your major cooldowns if you can!), after which he will erupt Excessive Electrification and resume the encounter.

• Always do your best to position the boss around the 4 Darkfuse Mechadrones and away from any Excessive Electrification ground patches.

• Use your major cooldowns during Jumpstart intermission.
• If Kill-o-Block Barrier last too long, call out for external defensives and use everything you have to keep your team alive.

• Be mindful of the Loaderbot's Wind Up fixate. This can be especially dangerous if you are a melee player!
• Interrupt Venture Co. Diver's Harpoon. Sidestep any Seaforium Charge ground bombs!
• Interrupt Venture Co. Surveyor's Surveying Beam.
• Avoid Shreddinator 3000's Shreddation Sawblade and sidestep the Flamethrower channel cast.
• Use your defensives if Venture Co. Architect casts Nailed on you, use defensive or a movement-impairing removal ability (like Paladin's Blessing of Freedom or Monk's Tiger's Lust. When they cast Rapid Construction, focus their construction as otherwise, they take reduced damage.

• Make sure to defeat both bosses simultaneously to avoid the Divided Duo Enrage effect.
• Use the Barreling Charge and Kinetic Explosive Gel to remove the bombs. If you don't clear all the bombs before the timer runs out, they will deal massive group-wide damage and apply Deflagration.
• Dodge the incoming B.B.B.F.G. frontals from Keeza Quickfuse.

• Be careful as Bront will cleave targets in front of you with Wallop frontal.
• Always do your best to position both bosses together, allowing your team a better cleave.

• Dispel the Kinetic Explosive Gel on top of a bomb to remove them. Be mindful as the debuff ticks hard, consider asking for a defensive.
• Use all of your major healing cooldowns if a bomb goes through as the Deflagration does immense damage.

• Be mindful at the quantity of Bombshell Crabs you are pulling as upon death they will detonate Crabsplosion - a group-wide stackable DoT effect.
• Interrupt Disturbed Kelp's Restorative Algae and use your crowd-control when they cast Jettison Kelp.

• Razorchoke Vines is the main mechanic to play around, as it will bind 4 random players (2 by 2). Your goal is to avoid being hit by Mudslide frontal and the incoming waves coming from Awaken the Swamp without breaking the 14 yards binding (else you will be pulled in together and likely die).
• Organize prior to engaging the boss, at what direction exactly you will be moving to avoid the Mudslide.

• Use your active mitigation when Swampface casts Sludge Claws.

• Use your major healing cooldowns to heal through the Awaken the Swamp as it will do group-wide damage.

• Avoid being hit by Bubbles's Bubble ground visuals. In addition, use your defensives when the mini-boss is casting Backwash.
• HIGH PRIORITY Interrupt Venture Co. Electrician's Lightning Bolt. Your healer must focus on dispelling Overcharge DoT as swiftly as they can.
• Darkfuse Jumpstarter is the hardest non-boss-enemy in this dungeon, as they will periodically do continuous group-wide damage while spawning Battery Discharge lighting puddles (which you must avoid otherwise you will die).

• Use defensive cooldowns during Turbo Charge and dodge the incoming frontals.
• Avoid the Dam Rubble ground puddles.
• If targeted by Gigazap, stay away from any water puddles to avoid electrifying them. This will help you with a follow-up boss ability - Leaping Sparks as the only way to remove it is through leading the spark onto a fresh water puddle.

• Use your major defensive cooldowns before each Thunder Punch.

• Use your major healing cooldowns during the Turbo Charge channel, as it will deal massive group-wide damage.
