AION 2 bosses: guides and spawn times

Each boss guide on Aion2help has a cheat sheet by role (tank, healer, DPS), the phases, every confirmed ability and how to counter it, and the Global vs KR differences. We publish a guide only when the mechanics are confirmed by NC or by at least two independent sources. Everything else is listed below as guide in preparation.

Status labels: [Official], [Community ×N], [Single source], [KR/TW].

Guides in preparation

These bosses exist on Global (or are announced), but their mechanics are not yet confirmed by two independent sources:

Boss	Where	What is missing
Kromede’s Desire	Fire Temple, Mirror Altar (Expedition)	Phase-by-phase mechanics; KR notes confirm only fire arrows and a stagger state
Talisra of the Void	Shattered Arkanis (Transcendence)	Second source for the colour-matching mechanics
Guardian Lord Nahma	Chaotic Lower Reshanta (Abyss)	Any combat mechanics
Executors Argo, Kaira, Tamasa	Chaotic Lower Reshanta (Abyss)	Any combat mechanics
Watcher Kaira	Chaotic Lower Reshanta (roaming)	Any combat mechanics
Zikel’s Apparition and other Nightmare bosses	Nightmare, Layer I	Second source for mechanics
Grandios and other invasion bosses	Dimensional Invasion	Any mechanics source
Silent Dartan, Soul Ruler Kashapa, High Commander Lagta, Eternal / Immortal Gartua	Field bosses	Any mechanics source; English names partly unofficial

Seen a boss that is not here, or have footage of a fight? Use “Found an error?” at the bottom of the page.

Abyss boss spawn times (Global)

Boss	Level	Spawn (server time)	Status
Guardian Lord Nahma	65	Fri and Sun, 21:00	[Community ×3]; KR uses 22:00–23:00 by matching group
Executors Argo, Kaira, Tamasa	65	Mon, Thu, Sat, 21:30 (after Artifact Siege)	[Community ×2]; KR uses Wed and Sat
Watcher Kaira	65	Every 3 hours from 01:00	[Community ×2]; KR: every 4 hours since Sep 2, 2026

NC made “Defeat the Boss Guardian Lord Nahma Once” a weekly Season Mission that gives an Abyss Entry Stone — [Official]. Nahma drops Refining Stones every time and an Artwork or Colossus item 25% of the time — [Community ×2]. Zone guide: Chaotic Lower Reshanta.

Field boss respawn timers

Boss	Level	Respawn after kill	Status
Silent Dartan	48	6 hours	Timer [KR official] + [Global guide]; level [Single source]
Soul Ruler Kashapa	48	6 hours	Same
High Commander Lagta	48	12 hours	Same
Eternal Gartua (Elyos) / Immortal Gartua (Asmodians)	—	12 hours	Same

Locations differ between sources, so we do not list them yet. Some names are our translations of the Korean names until we confirm the Global client spelling. Server time on Global is reported as UTC+9; convert it with our timers.

How we verify boss guides

1. Sources: NC notices (Global and KR), then community guides in several languages.
2. Rule: a mechanic goes into a guide only with NC confirmation or two independent sources. Two sites that share the same datamine count as one.
3. Labels: KR-only facts are marked; disputed numbers (HP triggers, enrage timers) show both values.
4. Drop rates: we do not publish them until two independent sources agree.
