Fulghor’s Everdark Sovereign version is even stronger, including a new phase. For this expedition, we recommend not bringing Guardian, as his lack of mobility will often get him killed in Fulghor's new phase. Wylder and Ironeye are good options due to their swift attacks and innate mobility, and Raider is the undisputed best Nightfarer for Everdark Fulghor, as his Retaliate skill is great in this specific fight. Everdark Fulgor deals mostly holy damage, so relics and passives that improve holy resistance are invaluable for this fight.
The fight starts off with Fulghor in phase 2, having access to his corrupted arm. His moveset is the same as the regular version, and he employs precise spear moves, holy attacks, and chaotic, wide-reaching arm slams. During this phase, you can deal lightning damage to knock him down and stagger him out of certain attacks. Keep your distance while he’s swinging his arm around and wait for an opportunity to attack.
Phase 3
At approximately 60% HP, Fulghor will leap into the air, and phase 3 will begin. Ranged characters like the Recluse and Ironeye can safely attack Fulghor during the animation, since there’s no attack afterward.
In phase 3, Fulghor no longer has his corrupted arm and transforms his weapon into a twinblade-bow hybrid. Most of his attacks become telegraphed, heavy-hitting holy moves. He gains several notable attacks:
Arrow Shot
Fulghor will stand on its hind legs and his weapon will glow white before firing a near-instant projectile at a player. This can be dodged with precise timing, but blocking or dashing can be tricky.
Holy Rain of Arrows
Fulghor will point his weapon at the sky and fire arrows that will follow nearby players for a short period. Getting caught in the arrow rain can be fatal, so avoid it at all costs by sprinting away.
Spinning Twinblade Attacks
If Fulghor spins his twinblade around, he'll perform multiple 360-degree swipes toward a player. Dodge into him or run away. You can listen for the holy audio cue to help dodge at the right time and retaliate after.
Twinblade Swipe
When the boss holds his twinblade in a vertical position, he's about to perform an uppercut swipe. Run to the sides or roll into him to safely avoid it and deal some damage after.
Twinblade Combo
When Fulghor holds his twinblade above him, he’s about to unleash a combo attack. He’ll target a player and attack multiple times. Dodging into him and getting onto his back is the safest strategy to avoid damage. This combo can be fatal if you’re caught in his front. Another viable strategy is to just sprint away, but you'll still need to dodge as Fulghor will follow you around.
Ultimate Airborne Shot
Fulghor can leap into the air and then target a player with a holy beam, signaling he’s about to unleash a devastating nova at his location. This can be seen by the thin ray of light emanating from Fulghor’s bow. After a brief delay, he’ll release a near-instant explosion at the location, dealing heavy damage. The safest option to dodge this attack is getting directly underneath him if you have time, otherwise sprinting in a perpendicular direction away from him. Other Nightfarers should get close to Fulghor and attack him after the attack.
