Eald'narche (boss)

Eald'narche is fought as a Notorious Monster twice in Final Fantasy XI: Rise of the Zilart and Final Fantasy XI: Chains of Promathia.

The Celestial Nexus
Eald'narche is encountered in Zilart Mission 16: The Celestial Nexus, as the Final Boss of the Zilart campaign. The encounter has two phases. During the first phase, he is standing on a floating platform, assisted by two Orbitals and surrounded by Exoplates. As long as the Exoplates live Eald'narche is invulnerable, so they must be defeated first. Eald'narche will cast all Ancient Magic and Sleepga II in this form.

In the second phase Eald'narche is no longer on the platform and has no assistance. However, he can now cast Bindga in addition to his previous spells, can teleport around the arena, has a blistering melee attack speed, and has several unique abilities. Vortex and Stellar Burst deal area of effect damage, with Vortex inflicting terror while Stellar Burst inflicts silence. Omega Javelin is a ranged attack which inflicts petrification.

Apocalypse Nigh
Eald'narche is encountered again in the quest Apocalypse Nigh, alongside his brother Kam'lanaut. He is mostly identical to the second phase of the Celestial Nexus version, but has higher stats and health, and casts tier III -ga spells instead of Ancient Magic.
