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.

Elden Ring offers its players a diverse range of grim bosses to fight, which is expected from a game made by the creators behind Dark Souls and Bloodborne. 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 we have put together a step-by-step guide on the location of Lichdragon Fortissax in Elden Ring.

Defeating Lichdragon Fortissax In Elden Ring

Fighting the Legendary. Lichdragon Fortissax

Like every other enemy you will face, the Lichdragon Fortissax has a repetitive moveset. So it won’t be very difficult to defeat him. This legendary boss uses lighting attacks as well as its hind legs and wings to attack you. And like all dragons, it breathes fire to attack its foes too.

Lichdragon Fortissax dragon uses its lightning in numerous ways, firing a lightning bolt in your way, emitting four electric waves that you should be prepared to dodge as they give you significant damage. Make sure you choose the best Melee weapons to fight him.

The worst attack that you should keep an eye out for is its aerial attack. The Lichdragon Fortissax flies high up and darts itself straight towards you. This attack is very hard to dodge because of its high speed. Once you see the Lichdragon Fortissax flying up in the air, be prepared to dodge him.

Besides observing his moveset, another strategy is to keep track of what animation is followed after various attacks because, unlike other bosses, the Lichdragon is quite slow. To deal damage on the Lichdragon Fortissax, attack its legs and tail. Weapons like Moonlight Greatsword can help you a lot in this battle as they take out significant health with each hit. You can also summon Spirit Ashes to help you in this fight.

Equipping some of the best Talismans that would increase resistance against lighting are also a good option. During the second phase of the fight, it is recommended that you use the Dragon Blight Coating on your weapon to help defeat the Lichdragon faster.
