The Tor Hammer is located in the Chamber of Lies, guarded by a Spirit and a Tyrant in the room with the second and final lever we need to pull to extend the bridge to reach the Annihilator (and the giant monster).
The Tor Hammer can be used to destroy the small Rhogar statues that we have seen about the place. In order to do this, you need to have Harkyn equip the weapon and make sure you have the two-handed option available (use triangle/Y to cycle between stances). Once that is good to go, you simply need to approach and melee each of them. There are four of these statues in total and destroying these will earn you the Armour Set (Last Traitor) .
They are located in the following areas:
**Chamber of Lies** - The room after where Yetka gave us the ability to read the runic inscriptions on walls. This will earn you the **Last Traitor (Wrist)** .
**The Panorama** – On the Panorama area above the Arena where we fought the Guardian. Right next to the snowy path leading down to the Abandoned Range. This will unlock the **Last Traitor (Head).**
**Altar Ruins –** On the second floor of the flying toast room (where we had to unlock the door for Yetka) on the side of the room leading to the roof. This will net you the **Last Traitor (Legs).**
**Chamber of Lies -** On the platform where we fought the first Dimensional Beast imbued with fire. Right near the entrance to the Annihilator’s boss fight arena. This will reward you with **Last Traitor (Chest).**
