Where it appears
How Triaggelos attacks — and how to dodge
- Meteor strikes (Assault Form) — Rains down meteor impacts across the arena during its aggressive Assault Form; the impact zones are telegraphed on the ground, so dodge by moving away from the marked areas before they land.
- Multi-part thrust combo (Assault Form) — A chained multi-hit thrust attack in Assault Form; the boss can be interrupted mid-charge before or during the combo windup, which applies significant stagger damage — punish the charge-up to shut down the combo.
- Dash attack (Assault Form) — A fast closing dash strike used in Assault Form; sidestep or dodge-roll away as it closes distance since it is a committed lunge.
- Ankhor shockwave (Search Form) — In Search Form the boss charges a wide shockwave that deals extreme Aether damage, which is fatal unless operators are standing near Originium Branches for protection — position near an Originium Branch before the charge completes.
- Summon minions (Search Form) — Search Form summons adds to support it; killing the summoned minions applies stagger damage to the boss, so prioritize clearing them quickly rather than ignoring them.
- Invisibility (Trickery Form) — In Trickery Form the boss becomes invisible and cannot be locked onto; landing a hit on it while invisible reveals it for 3 seconds and applies bonus stagger damage, so track its last known position/audio cues and attack blind to force the reveal.

Aggelos
The Aggelos (plural: Aggeloi) refers to any hostile and animated entity comprising natural matter and a halo structure, and is created by an Ankhor via catalytic construction. Throughout the history of humanity's expansion across Talos-II, the Aggeloi have always been our primary threat. The Aggeloi War was named after the enemy fought by humanity.
There are 4 currently verified modes of Aggeloid behavior: (1) construction; (2) deconstruction; (3) mimicry; and (4) attacking humans / human-built objects. However, since the Ankhor-induced Aggeloi formation process resembles that of industrial production, we are uncertain if the Aggeloi can be classified as a living or biological lifeform.
The construct pattern of an Aggeloid entity refers to its outward appearance, mode of movement, and means of attack. A single Ankhor tends to create Aggeloi with only a limited number of construct patterns, though they may include occasional non- or alter-pattern variants. Hence, an Ankhor's property is defined by the range of Aggeloid construct patterns it can create.
Since the First Aggeloi War, humanity has encountered new construct patterns of Aggeloi, giving rise to the Standard Aggeloid Classification (SAC) system. SAC is designed to help users search and identify weaknesses and best tactics for neutralizing a particular Aggelos.
Currently, most Aggeloid threats come in the form of raids stemming from unknown sources or random Ankhorfalls. Nevertheless, humanity's history records described how the entirety of the Northern Frontier was destroyed within 24 hours after the First Aggeloi War broke out.
The Aggelos is likely to remain as the greatest challenge faced by human civilization on Talos-II.
