How to defeat Eterllick the Tracker in First Descendant
Eterllick has a pesky shield that makes him invulnerable to damage, but once you get past it, the battle is not that hard. Follow these steps to make short work of the boss:
Destroy the shield sphere
- Locate the three orbs circling Eterllick that power the shield
- Focus your fire on these orbiting machines
- Once the sphere is gone, Eterllick becomes vulnerable
- DPS his HP as hard as you can.
Beware of the final flash
- When Eterllick’s HP goes to zero, it detonates itself
- Look for a yellow energy beam surrounding Eterllick
- This indicates the area which will be affected by the blast
- Immediately run away from the zone
Repeat the Process
- Return to the first step and cycle through the steps again
- You'll need to defeat Eterllick a total of three times
