Here is the information for the final 1.5 Berserker Epic Fight. It does not list the room location on Alla, but it does give a location.
Testing the Axes
Bring a small raid to Old Sebilis. Kill the four static juggernaut spawns near -180, -1550 (exact location of room needed). This will cause an Ancient Sebilite Protector (red /con to 70) to spawn along with two untouchable adds (A Sebilite Guardian, red /con to 70) that will heal it. The Protector hits for 1600 max, AE rampages, and procs Death Shackles starting at 75% (which is when the guards begin to heal it as well). The Guardians proc Blurring Focus, Complete Heal, and Curse of the Protector. During the fight, you need to wield each of the four trial axes until you see one of the following messages and the axe gets moved to your cursor:
- After several heavy swings, the axe shatters into many fine pieces. Time for a new axe!
- After raining down nearly two dozen blows you begin to notice small hairline fractures developing in the axe head. You think testing for this axe has been completed.
- After many swings you can feel this axe is failing and think that it will fall apart at any moment. You think that testing for this axe has been completed.
- The rigors of battle have had no effect of this axe. Keras should be very pleased with the result of this particular axe.
