Deep within the Deeproot Depths lies one of Elden Ring's most visually striking optional encounters: Lichdragon Fortissax. This corrupted ancient dragon presents a unique challenge for Tarnished players seeking to complete Fia's questline. Understanding Fortissax's attack patterns, elemental affinities, and key vulnerabilities is crucial for emerging victorious from the Deathbed Dream.
Unlocking the Encounter and Preparation
Accessing the fight requires progressing Fia's questline to its conclusion inside the Deeproot Depths. Players must defeat Fia's Champions and give her the Cursemark of Death to enter the Deathbed Dream where Fortissax resides. Equipping gear with high Lightning and Holy resistance will significantly reduce incoming damage during the encounter.
Preparing your character with fast-striking physical weapons or powerful ranged sorceries makes a major difference. Staying informed via daily gaming news can help players discover optimized character builds suited for late-game dragon encounters. Additionally, bringing Spirit Ashes that can draw aggression allows melee fighters to target weak points more safely.
Key Weaknesses and Damage Opportunities
Lichdragon Fortissax shares the anatomical weak points common to most ancient dragons in the Lands Between. Hitting the head deals substantially higher damage compared to striking the legs or body, potentially triggering a stance break. However, staying directly in front of the head exposes you to dangerous lightning sweeps and breath attacks.
Unlike many undead or corrupted foes, Fortissax possesses notable resistance to Lightning and Holy damage. Players should prioritize physical damage types such as Pierce or Standard, or leverage status effects like Hemorrhage and Frostbite. Utilizing Strike damage on the legs can also yield consistent results when head access is limited.
Combat Strategy and Avoiding Lightning AOE
The defining mechanic of the Fortissax fight is the constant ambient death lightning that tracks the player. Red lightning stakes periodically drop around the arena, requiring continuous movement even while finding windows to attack. Maintaining a balanced camera angle ensures you remain aware of localized lightning strikes while monitoring the dragon's body movements.
During the second phase, Fortissax enhances his claws with red lightning for devastating slam attacks. Dodge inward toward his hind legs when he rears up to execute claw sweeps, avoiding the immediate blast zone. When he takes flight to cast sweeping fire or lightning beams, sprint laterally across the arena to outrun the area-of-effect paths.
Boss Rewards and Significance
Defeating Lichdragon Fortissax rewards players with a substantial amount of Runes and the Remembrance of the Lichdragon. This Remembrance can be traded at Roundtable Hold for powerful incantations, including Fortissax's Lightning Spear and Death Lightning. Obtaining these spells grants faith-based characters access to some of the most spectacular offensive magic in the game.
Beyond the immediate item rewards, vanquishing Fortissax allows players to collect the Mending Rune of the Death-Prince. This key item unlocks an alternate ending for the main storyline, making the fight essential for lore enthusiasts. Defeating this formidable dragon stands as a memorable test of patience, positioning, and build preparation.
