Tips and Tricks
- Fanged Lunge is a gap closer which leaps to a target. Follows up with Heavy Stomp.
- Heavy Stomp is an untelegraphed circle AoE around Arch-Eta applying a
Vulnerability Up. - Energy Wave is an untelegraphed column AoE in a random direction. Move out of its path.
- Sonic Howl is an unavoidable large AoE which takes advantage of any Vulnerability Up stacks.
- Tail Swipe is an untelegraphed conal AoE behind Arch-Eta applying a Vulnerability Up.
- Steel Fang is a telegraphed tank buster on the main target.
Description
“What traits mark organisms as “alive,” you doubtless wonder! Ahem. Most possess reproductive capabilities, the ability to evolve and adapt, and survival instincts or mechanisms. Even a machine, should it possess all of these traits, would be classified as a living organism.
Which brings us to Omega. Was it, in fact, alien life? Yes, says I!
To prove this, naturally, I require evidence both that Omega came to us from the sea of stars as the Allagans wrote, and that its species satisfies the conditions I described. Evidence of evolution from its home star, in other words!— Chrysielle, Old Sharlayan Aetheryte Plaza, Old Sharlayan
Lore
“As total conversion of consciousness was proving difficult, this unit's creators sought to imprint solely the base instincts of a living entity. The Eta's befittingly bestial frame is likely based on a creature that once roamed the Alphatron Star.
— Encyclopædia Eorzea Volume III, p. 77
“Living organisms are defined by reproductive capabilities, the ability to evolve and adapt, and survival instincts or mechanisms. Ergo, even a machine such as Omega might be classified as a living organism, assuming it satisfied the aforementioned conditions. True proof of this assertion, however, would required the study of an earlier link in its species' evolutionary chain from Omega's home star, if it still exists.
