“So begins the third phase of Operation: Archon, which entails a frontal assault upon Castrum Meridianum, Gaius van Baelsar's seat of power. Forming the main thrust, the Immortal Flames will strike at the stronghold with all their strength, though this is but a feint. While the garrison's eyes are drawn outwards, you and your comrades must steal past its defences and attempt to deactivate the magitek field which protects the Praetorium, the fortress within a fortress wherein the Ultima Weapon is believed to be housed.

Livia sas Junius
Part 1
- In this fight, players have to defeat Livia sas Junius in her Magitek Armor. In the boss room, there are Mark XLIII Artillery Cannons with Magitek Missle piles near them. When players click on these cannons, Magitek Loaders will load the cannons with missiles. Players can fire the cannons to do 3000 damage to Livia. One of the tanks should fire the cannons because the act draws the aggro of the boss. Tanks should tank Livia in the center of the room, away from the cannons, because Livia's cleave attacks could damage and destroy them.
Apparently, the cannons are controlled by a skill bar change. Click on the ammo pile to cause the claw to load the cannon nearby, then click on the cannon, use the Skill bar that changed to aim the cannon at Livia and then fire it. [Could someone add some pics of the console and PC skill bar popups?]
- She will spawn adds throughout the fight. One of the tanks should take their aggro and prevent them from destroying the cannons.
- Abilities
- Photon Stream is an instant frontal attack that deals a small amount of damage
- Magitek Cannon is a large circular AoE attack that targets a random player. It deals heavy damage to all players caught in the AoE.

- At 3/4 and half HP, Livia will spawn a group of 7th Cohort Secutor Adds. They will target all target one player. That player should stay still so rest of the party members can AoE down the adds. At quarter HP, Livia will spawn a Magitek Colossus along with a group of 7th Cohort Secutors. One of the tanks should take the aggro of the Colossus while the rest of the group AoE down the Secutors and burst down the boss.
