Cosmic Empowerment
Use the Cypher of the First Ones to cleanse one of Antros' Destruction Cores.
Cosmic Empowerment is a 10-point achievement earned by using the Cypher of the First Ones to cleanse one of Antros' Destruction Cores during the Zereth Mortis world boss encounter.
Unlock Trebalim Understanding
Before engaging Antros, you must unlock the Trebalim Understanding power through the Cypher research console. This is the last upgrade on the top row and allows you to interact with Antros' Destruction Cores during the fight.
Travel to Antros
Head to Antecedent Isle in Zereth Mortis and find the world boss Antros at 48.8, 5.4. You can use the Ancient Translocator at 46.1, 21.8 to reach the area.
Cleanse a Destruction Core
During the fight, Antros will cause large orbs to rain down across the battlefield. Run up to one of these orbs and click it to cleanse it — this is what completes the achievement. You do not need Pocopoc summoned to click the orbs, and standing in the white zone on the floor also grants a 15% damage buff.
Tips
If Antros dies before the orbs spawn due to high player numbers, try joining a smaller group or waiting for a lower-population attempt so the fight lasts long enough for the Destruction Cores to appear.
See the video guide for a visual walkthrough of the orb interaction.
