TSO Raid Zones by Difficulty

1. First 2 named in Tomb of the Mad Crusader.
2. First named in Palace of the Ancient One.
3. Next 2 named in Tomb.
4. Next 4 named in Palace.
5. First named in Ykesha’s Inner Stronghold.
6. Final named in Tomb.
7. Final named in Palace.
8. Zarrakon (in Zarrakon’s Abyssal Chamber naturally)
9. Rest of Ykesha’s Inner Stronghold.

In response to this list, there has been some conjecture that Zarrakon is slightly easier than the final named in the Palace. Ykesha in Ykesha’s Inner Stronghold is considered to be the hardest mob in the game.
