Elden Ring Lichdragon Fortissax Location Walkthrough

We have put together a step-by-step guide on Elden Ring's Lichdragon Fortissax boss Location. Finding it is tough as it is a hidden boss.

The Lich Dragon Fortissax is one of the most anticipated bosses in Elden Ring, which is for a good reason since Dragon incantations are powerful spells that can aid you along the way. Some of the best incantations, especially the dragon ones, can be unlocked after offering the Dragon Hearts at the Church of Dragon Communion and the Cathedral of Dragon Communion. This legendary Dragon requires a quest to be unlocked and can be quite difficult to find, so I have put together a step-by-step guide on the location of Lichdragon Fortissax in Elden Ring.


Key Highlights

  • Lichdragon Fortissax is an optional boss in Elden Ring located in Deeproot Depths.
  • It can be fought after progressing halfway through Ranni’s questline until the player gets the Cursemark of Death and give it to Fia
  • At the end of Fia’s quest line, the players get summoned into the Deathbed Dream, where they can fight Lichdragon Fortissax.
  • The moveset of Lichdragon Fortissax consists of lightning bolts, lightning waves, claw attacks, flying attacks, and more. Talismans and armor set that negate lightning damage are recommended against it.
  • The boss fight is mandatory for Fia’s questline for triggering the Age of Duskborn ending.

Remember when you gave the Black Knife print to Sorcerer Rogier? If you talk to him again, he will promise to study it and send you to meet the NOC Ranni. You will find her at the end of Caria Manor, located in the north of the Academy of Raya Lucaria. Her quest requires you to give her a key item.

Before you head out to find the treasure, aka the key item, don’t forget to talk to Iji and Seluvis. Now head over to Nokron, Eternal City again. When you enter the city, make your way down the roofs of the buildings on your right side. The horizontal building on your left will help you get to the other side. Go inside the building on your left side and dropdown. Moving forward past the door will lead you to the Site of Grace.

Go to the building up ahead on the right side and walk down the stairs. Run to the path on your right till you reach the statue. Turn left here and run straight down. Near the end of this path, turn left again and go into the bushes. You will spot a path behind the hills. Drop down from this path on the ledge, and you will find yourself in the Night’s Sacred Ground.

Inside the main building, climb the stairs, and you will find the treasure underneath the giant corpse throne, the Fingerslayer Blade. Return to Ranni and give her this key item. In return, she will give you a Carian Inverted statue.

Run straight down and go inside the tower in front of you. Use the lift to go up and climb the stairs to get to the roof. In the middle of the roof, you will see the Cursemark of Death, as shown in the image above.

Defeating Lichdragon Fortissax In Elden Ring

Fighting the Legendary. Lichdragon Fortissax

Defeating the Lichdragon Fortissax in Elden Ring can be challenging, but with the right strategies, you can emerge victorious. Here are some tips for this epic battle:

  1. Understand the Moveset: As with many bosses, Fortissax has a repetitive moveset. Familiarize yourself with its attacks, which include lightning bolts, electric waves, fire breath, and aerial dives.
  2. Melee Weapons: Choose powerful melee weapons for this fight. Weapons like the Moonlight Greatsword are effective for dealing significant damage to the dragon.
  3. Dodging Aerial Attacks: Be especially cautious when Fortissax takes to the air for its aerial attack. It’s fast and can be hard to dodge, so be prepared to evade its charge.
  4. Target Weak Points: Focus your attacks on the dragon’s legs and tail to deal damage. These are its weak points, and consistent strikes will whittle down its health.
  5. Spirit Ashes: Consider summoning Spirit Ashes to aid you in the battle. They can provide additional damage and distractions, giving you an advantage.
  6. Resistance Against Lightning: Equip talismans or gear that increase your resistance against lightning attacks, as Fortissax heavily relies on lightning-based moves.
  7. Dragon Blight Coating: In the second phase of the fight, use Dragon Blight Coating on your weapon to increase your damage output and defeat Fortissax more quickly.

By employing these strategies and staying patient, you can conquer the Lichdragon Fortissax and claim victory in Elden Ring.

My Tips On Beating Lichdragon Fortissax

Lichdragon Fortissax is one of the trickiest bosses to fight if you’re not leveled properly in Elden Ring. Usually, you won’t have enough HP to fight it and dodge all attacks rationally, so it’s best if you try to tank damage by getting your HP up to a very high level, but be sure to dodge his electric arts.

Weapons that have shorter attack animations work best, as the boss likes to keep moving around very swiftly. Attacking on the head deals significantly higher damage as compared to the body, so that can be used very effectively during the fight. Finally, make sure you’re wearing Lightning-resistant armor to minimize damage taken from the dragon’s Lightning attacks.

We hope this guide will help you find the Lichdragon Fortissax’s location in Elden Ring. If you have any questions, feel free to ask them in the comments below.
