With a Heart of Fear

Steps
You need to kill some mobs being part of a ring event at the bone towers. Kill all Fetid Fiends around the towers to spawn them inside. If you don't get the message "You feel a presence nearby", than some fiends are left. Once the nameds are defeated you have to loot Heart of Fear and corrupted mind from the skull in the middle of the tower.


 * 1) Investigate the first sacrificial well at : Clear the Thulian Berserkers (in pairs, 73^^ and 73^^^). When you kill the Thulian Caller (73^^^) at each side of the triskele-shaped altar, the corpse is persistent. Have a very tough member of your party drag the corpse to the small round dais in the center of the altar. The corpse will appear red as you move it, and turns green when you are in the right place. You usually have to stand right on the center altar in order to place it correctly. Immediately afterwards, a Frightflyer will spawn (73^^^). Defeat it and "You hear a loud pounding as a heart appears at the center of the altar." Repeat the process twice more, and a cute little pudding-like ooze will appear in the center of the altar. Pick it up - this is a heart of fear.
 * 2) Investigate the second sacrificial well: The other altar is in the eastern part of the zone, past the Scareling Bogs, at . Use the same process as before and collect another heart of fear.
 * 3) run up to the portal tower near the wall of fire. It is in Terrock's Bite, at .There are two braziers in front of the tower. Use them to offer up the two hearts you just collected. Kill the spawning Spinechiller Spiders, enter the tower and swim down the well in the middle.You will suddenly find yourself in the courtyard of the Shrine of Thule, on the other side of the fiery wall. Activate six of the firepots in front of the pyramid with the Heart of Fear and Corrupted Minds from Through Gnomish Eyes, which will spawn Terror 76^^^ Epicx2 on top of the pyramid.
