At the end of Blood on Parchment in Diablo 4, players uncover the long-lost location of Diablo 4 Items the Sword of Horazon - a legendary relic tied to the ancient mage himself. Fittingly, this sets up the next major step in the Season of the Infernal Reign storyline, with a quest aptly named Sword of Horazon. This mission offers one of the most lore-rich and combat-heavy experiences of the season, packed with cultist encounters, dungeon crawls, and waves of demonic foes.

Before diving in, ensure you've reached Tier 8 reputation with the seasonal faction. If you haven't yet, you may need to complete Bartuc's Reign of Chaos side quest or revisit certain Infernal activities to boost your standing. Players looking to buy Diablo IV Items can often save time optimizing their builds for the long fights ahead, especially if you're not yet geared for high-tier encounters.

How to Begin the Sword of Horazon Quest

To begin Sword of Horazon in Diablo 4 Season 10, use the Waypoint for Fate's Retreat and speak with Shyan, your recurring ally in this chain of quests. She'll inform you about nearby cultists attempting to guard the location of the sword. While there's no direct vault marker yet, the nearby cult activity provides a clear lead.

From Fate's Retreat, ride east through the Path of Stray Souls until you reach the Cultist Camp. You'll face numerous waves of cultists and demonic minions here - they're not particularly dangerous, but they can swarm you if you're under-leveled. If you're playing a Minion Necromancer, your skeletons and golems will make short work of these enemies. Once you clear the area, speak with Shyan again to progress the quest.

Exploring the Vault of Sins

After dealing with the camp, Shyan will direct you toward a newly discovered dungeon - the Vault of Sins. Despite her earlier doubts, the vault truly exists, and it's a crucial part of this quest. Like most Diablo 4 dungeons, the layout here is randomized, so expect to adapt as you clear cultists, demons, and corrupted guardians.

Your main goal inside the Vault of Sins is to locate the Inner Sanctum Door, which you'll soon discover is sealed by a magical barrier. Near it lies a Blood Basin, requiring specific ritual components to unlock passage.

Collecting Blood for the Basin

Check your map and you'll see two new markers labeled "Collect Blood for the Basin." These indicate areas where cultists and sacrificial victims can be found. Travel to either site and interact with the Corpse to collect the first batch of blood. Bring it back to the basin to partially fill it.

Unfortunately, one offering won't be enough. You'll need to repeat the process at the second collection point. Once both offerings are placed, the barrier surrounding the Inner Sanctum door will dissipate, granting access deeper into the dungeon.

If you're grinding through this area repeatedly, you can use Diablo 4 Items like high-tier elixirs or infused potions to sustain yourself during prolonged fights. The dungeon features multiple elite mobs, so cheap D4 materials extra durability can make the process smoother and faster.
