Completing Paladin Isaac's questline in Lords of the Fallen gives players access to powerful gear and unlocks the formidable Dark Crusader starting class. To fully realize this journey, adventurers must track down memories, navigate the realm of Umbral, and face Isaac himself in a dramatic boss battle. Following this quest requires careful exploration across multiple key locations throughout Mournstead.
Beginning Paladin Isaac Quest in the Defiled Sepulchre
Your journey begins early in the game at the Defiled Sepulchre, where you can acquire the Flayed Skin key item. Gathering this item sets the entire questline in motion and serves as the catalyst for unlocking Isaac's backstory. Players must keep this item safe as they progress further into the dangerous regions of the game world.
Tracking Stigmas Across Mournstead
To advance the narrative, you need to locate and soulflay specific Stigmas scattered across different zones. These memory echoes can be found in places like Lower Calrath, Fief of the Chill Curse, and near the Path of Devotion. Interacting with each Stigma reveals crucial lore details about Paladin Isaac's past and his confrontation with the Lightreaper.
Defeating Paladin's Burden in Battle
After viewing the necessary memories, head to the Path of Devotion and enter the Umbral realm to challenge Paladin Isaac as Paladin's Burden. This optional boss uses agile melee strikes, Radiance spells, and healing abilities to test your combat patience and timing. Defeating him rewards you with the Umbral-Tinged Flayed Skin, allowing you to unlock the door in the starting area.
Confronting the Lightreaper and Unlocking the Dark Crusader
To conclude the questline, you must summon Paladin Isaac as an NPC ally during the boss encounter against the Lightreaper. Defeating the boss with Isaac present completes his storyline and grants you his complete armor set and weapon. Fulfilling these conditions also unlocks the iconic Dark Crusader class for future playthroughs.
