How do you solo the boss FORT DES JUMEAUX DE FER?

The method which is currently operating at the Fort of the Iron Twins in Raid Shadow Legends is based on a team built around the Géomancien. Solo travel has not been possible since late September 2022.

The Method Parangon has been rendered obsolete by a buff to the boss on the Plarium in September 2022.

This dungeon resets every day, and its Affinity changes daily. This guide covers Step 15 and the lower levels. Each affinity has its own 15 steps.

The original concept was simple: a single champion would take the boss and defeat it on their own. This is no longer possible since Update 6.10.

Mechanics of the boss at Fort des Jumeaux de Fer

Before choosing your strategy, it's helpful to understand how this boss works in the game.

Despite their name, the Iron Twins are a single boss : a massive metal golem, fought head-on without a wave of minions.

There are several key mechanical features of the boss that you should be aware of:

• He takes 50 % of damage less per additional hit from a multi-hit ability. When their HP falls below 85 %, 70 %, 55 % and 40 %, it hits your entire team and removes its debuffs. The goal, therefore, is to use single-target attacks based on maximum HP, or passive damage effects like poison and Combustion.
• Its affinity changes every day, which means you'll need to adjust your team composition to match the current affinity.
• It can apply debuffs to your champ and slow down their rate of action.
• Starting at the higher levels, it becomes absolutely essential to have a solid team composition to last the entire battle.

Given these mechanics, a team built around the Géomancien (Combustion and Damage Reflection) is the best choice for progressing through this dungeon.

Affinities and Schedule for Fort des Jumeaux de Fer

L'The affinity of boss changes every day. The four affinities follow one another in rotation: Void, Magic, Spirit, and Strength.

When facing an affinity that overpowers your champion, you have a 35 % chance of landing a weak attack.

A weak attack deals less damage and does not apply a debuff, regardless of your accuracy.

Warning: In this dungeon, any champion whose affinity differs from that of the boss makes it more resilient. Prioritize champions with the same affinity as the day’s boss.

Check the fort's daily schedule in the game to plan your keys based on the active affinity.

The Paragon Strategy for Fort of the Iron Twins: Prerequisites

Since update 6.10 on September 29, 2022, this method no longer works in solo mode. It is included here for informational purposes only. For a solution that currently works at the Fort of the Iron Twins, check out the Geomancy Guide.

This solo technique is based on Parangon, mounted in 6 stars to last the entire fight. Here are the prerequisites for attempting this solo run on the Iron Twins:

• Parangon Full book, focusing on his A2 (Damage Control), which grants him the Invincible buff.
• A character that can reach a minimum speed of 250 with a Toxic set
• Time ahead of you: the The fight lasts about 12 minutes

It's doable if you're already running on the Drake 20–25 and that you've farmed it a lot. The idea is to stack the poison to snack on the Max HP from boss. To improve your essay, add these elements:

• The master's degrees oriented war master and special debuffs
• Regarding the Artifacts Strike Back to increase the number of attack rounds

Combat Techniques Against the Iron Twins

Set your tone Parangon with Minimum speed of 251. The faster you go, the more attack rounds and stacks of poison.

In Auto-AI, prioritize A2: it's the one that keeps the Invincible buff active at all times. The poison comes from the Toxic set.

Once everything is set up, start the battle in solo mode and let the auto-battle run. Count between 10 and 15 minutes depending on your gear, your master's degrees and the RNG.

Back then, the strategy was the same regardless of the active affinity, and the boss would drop on its own. On days when the Void wasn't active, the Parangon (Champion of Nothingness), however, boosted the boss's DEF.

Paragon gear and masteries for the Iron Twins Fortress

The "Toxic" set, combined with the "Warmaster" mastery, is at the heart of this strategy. Each counterattack inflicts an additional dose of poison, which accelerates the depletion of the boss's HP. On the master's degrees, prioritize the tree Insulted to maximize poison damage per turn in this dungeon.

Here is a concrete example of a setup for this dungeon:

Recommended Stats for Paragon Masteries

To ensure this strategy works on the highest levels of the fort, here are the stat thresholds to aim for on your artifacts:

• Speed : 251 minimum, 280+ recommended for faster performance
• Note: 220 minimum
• HP : as high as possible to last the 10- to 15-minute battle
• Defense : 3,000+ to survive without dying

• Géomancien : the go-to solution today. More reliable since the boss buff. Check out the dedicated guide to see his gear and his masteries.
• Invincible Team Strategy / Damage blocking : a well-coordinated team with great speed, featuring champions such as Helicath Where Roschard. Note: If HP is below 40 %, boss ignores Invincible with its A1.
• High-Resistance Strategy : Block the boss's debuffs using very high resistance, for champions who otherwise can't survive.
• Burn Strategy : Use "Combustion" instead of the poison. It remains effective, but the boss takes less damage from it, and each tick is capped.

Every solution has its own requirements and limitations. The goal remains the same: to pile on damage against the Max HP Use boss to take him down without getting eliminated before the end of the fight.
