Marble Aggelomoirai is a Boss enemy of the Aggeloi family in Arknights: Endfield. You will run into it in Energy Highlands. The core starts invulnerable, immobile and does not attack directly; it lets its detached limbs do the fighting and is immune to Corrosion in this state. Destroy the limbs to force the core to expose itself, and burst it only during that exposure window.

Where it appears
How Marble Aggelomoirai attacks — and how to dodge
- Sealed Core (Phase 1) — The core starts invulnerable, immobile and does not attack directly; it lets its detached limbs do the fighting and is immune to Corrosion in this state. Destroy the limbs to force the core to expose itself, and burst it only during that exposure window.
- Phase Transition — When the sealed core's HP hits zero, a cutscene plays and it rises into a mobile humanoid form that fights directly with spear, sword and arm weapons. Save burst cooldowns for this phase, since the sealed phase only takes damage in short windows anyway.
- Quick Sweep — A fast sweeping strike with an extremely short windup. The visual telegraph is nearly unreadable, so react to the audio/ally warning cue and dodge sideways rather than waiting to see the swing.
- Five-Hit Arm Combo — Chains five consecutive hammer-like blows; the fifth hit tracks your position. Do not burn your dodge early on hits 1-4: save the i-frame dodge for the homing final blow.
- Triple Energy Barrage — Fires three energy projectiles in quick sequence. One well-timed perfect dodge covers all three, so dodge on the first shot rather than trying to strafe each one.
- Spike Thrust + Delayed Blast — A limb rises and plants a delayed explosion in the ground under you. The blast zone is marked before it goes off; simply walk out of the marked area before the timer expires.
- Lingering Energy Sphere — Drops a red energy sphere that leaves a persistent damage field on the ground. Do not try to tank through it: it is a zoning tool, so reposition and keep fighting outside the circle.
- Spear Combo (3-hit) — A three-strike spear combo with long reach that can chain into follow-up arm hits. Attacks in this phase flash red just before impact, so watch for the red cue and perfect-dodge on it.
- Javelin Throw — Hurls a javelin that detonates a moment after it lands. Dodge the initial throw, then move off the impact point again before the delayed secondary blast.
- Sword Three-Slash (charged finish) — Three sword strikes where the last is a charged, heavy hit. That charged finisher can be interrupted with a skill/war-art or link attack during the wind-up, denying the big damage entirely.
- Spin Slash — A wide spinning diagonal sword attack covering a full circle around the boss. There is no safe side, so dash out beyond the spin radius instead of trying to roll through it.
- Sword-into-Spear Chain — Two sword slashes flowing straight into a spear strike with no interruption window. It must be dodged, not interrupted, so keep a dodge charge in reserve when in melee range.
- Charged Leap Strike — A single heavy leaping attack telegraphed by a red circle cue. Because it is a charged move, a skill or link attack lands during the charge to interrupt it before it connects.
- Hammer-into-Spear Explosion — A hammer swing flowing into a spear thrust that ends in an explosion. Treat it as one long chain: keep dodging through the sequence rather than trying to counterattack mid-combo.
- Flying Charge Shockwave — The boss flies in and slams down a shockwave. The cue is a white flash: jump on the white light to clear the ground-level shockwave.
- Meteor Rain — It rises to high altitude (briefly invulnerable), performs two slams, then a heavy landing; jumping prevents the landing impact. The meteor barrage mixes large fixed-position impacts with smaller player-tracking ones, so keep moving to shake the tracking meteors while eyeballing the fixed craters.
- Scatter Shot (double volley) — Fires two separate volleys of scattered shots. One dodge does not cover both, so time a second dodge for the follow-up volley.
How to beat Marble Aggelomoirai
Chapter 1 · Process IV — Undying Embers
Phase 1 — first form
- Watch for its tentacle attacks at range — they reach further than they look, so don't just stand still.
Phase 2 — after it transforms
- Manage your SP so you can keep firing off Skills back-to-back once it transforms — this phase punishes running dry.
- Play evasion-first in the second form — dodging is your main tool here, not tanking hits.

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.
