Raid Progression

Raid Progression in House of Thule is very linear. You start with access to the Tier 1 raids (after doing the progression mission in the zones).

Tier 1

• Ritual of Terror
• Tick Tock

Tier 2

Once you have completed both Tier 1 raids (and the group missions) you can request the Tier 2 missions. Each yields 2 Rusty Gate Key, the flag for Tier 3.

• The Roots of Evil
• Terror in the Dark
• The Librarian's Nightmare
• The Torches of Truth

Tier 3

After you have clicked your key (and done the missions) you have access to the first three Tier 3 raids:

• Guardian of the House
• The Force of Eternity
• At World's End

These raids drop 3 Tremulous Key which flag you to access the next raid:

• Cazic's Final Stand

Defeating Fear as well as the prior three Tier 3 raids allows access to :

• The Awakening

Fear drops 4 and Morell drops 6 Sanctus Key, the flag for Tier 4.

Tier 4

After clicking the Sanctus Key you can access the final tier of raids:

• Taking the Tower
• The Essence of Dreams
• Under the Sea
• Islands of Sand
• Elements of a Dream
• The Cages of Testing
• Morell Ascendant
