Master the Obsidian Sanctum raid in World of Warcraft. Learn strategies for Vesperon, Tenebron, Shadron, and the final boss, Sartharion, including tips for achievements and loot.

The Obsidian Sanctum is a raid located beneath Wyrmrest Temple in Dragonblight. It features a main boss, Sartharion, and three sub-bosses: Vesperon, Tenebron, and Shadron. While the sub-bosses drop emblems, only Sartharion drops raid loot. Leaving the drakes alive can grant achievements and better loot, but all trash must be cleared to engage the main boss.

Bosses: 1 to 4 (Sartharion + up to 3 drakes)

Zone: Dragonblight

Difficulty: ***

Walkthrough
  1. 1
    Trash Mobs: Clear all trash leading up to the bosses. Be aware that any remaining trash will join the boss fight.
  2. 2
    Drake Encounters (Optional/Strategic): The drakes are positioned clockwise from the entrance. It's possible to clear trash while leaving drakes alive by hugging walls. Every boss should be tanked away from the raid.
    • Vesperon: Not essential to defeat for progression, but some players may need to enter his portal. He can be burned down without the portal. Leaving Vesperon alive applies a 25% less health debuff to Sartharion.
  3. 3
    Tenebron: His portal spawns eggs that hatch into whelps. These whelps can be AoE'd down and ignored. Leaving Tenebron alive applies a 100% shadow damage taken debuff to Sartharion.
  4. 4
    Shadron: For this encounter, send all DPS into the portal with only the Main Tank (MT) and healer remaining outside to burn down the add. Leaving Shadron alive applies a 100% fire damage taken debuff to Sartharion.
  5. 5
    Sartharion: The main boss.
    • Positioning is crucial: No players should be behind or in front of Sartharion due to his cleave and tail sweep (which stuns). All DPS should stand to the sides of his belly.
  6. 6
    Watch for flame waves: A warning will appear before waves form. Look to both sides to see their origin and move to avoid them. More complex patterns may require careful movement.
  7. 7
    Adds: Off-tank any adds that spawn. Adds hit by flame waves can be de-raged or kept out of the fire.
  8. 8
    DPS Race: If mechanics are handled correctly, the fight can become a DPS race.
Tips
  • Tank all bosses away from the raid group.
  • If leaving drakes alive, hug walls to clear trash without engaging them.
  • Pay close attention to Sartharion's tail sweep and flame wave warnings.
  • Coordinate DPS on adds and the main boss effectively.
  • Emblems from sub-bosses.
  • Raid loot from Sartharion.
  • Potential for better loot and achievements if drakes are left alive.
