Mithrix

Mithrix is the final boss of the game found in Commencement, the final stage.

Phase 1
Mithrix will start by doing his basic attacks, which consists of running around, teleporting at you with his hammer, smashing the ground with his hammer to cause a shock-wave, and shooting you with needles similar to that of the Visions of Heresy. His more advanced attack is jumping into air of the center of the stage and slamming down, causing a 360 shock-wave around the stage. The wave ends when it reaches the thin line made of rocks between the platform where he is first seen and the outer platform with a small slope.

Phase 2
Terrain changes (several stone pillars rise up) and several Lunar Chimera Golemss and Lunar Chimera Wisps are summoned which must be defeated. Mithrix is not present during this phase while new chimeras are occasionally summoned.

Phase 3
Mithrix comes back with more powerful and different attacks, occasionally summoning Lunar Chimera Golems. His moveset is similar to the one in the first phase but the attacks have other effects to them. He also gets more aggressive and attacks more often. His slam will leave a lingering pillar of flames that will damage the player if they walk into it. After he lands from the jump he will summon moving lines of flame that spin around him and explode after a while, disappearing to make place for new ones. After a few rotations, he will get up and begin attacking with his melee again.

Phase 4
Mithrix steals all players' items and gains their buffs. Hitting him gives some items back. He will fire a burst of projectiles similar to those fired by using Visions Of Heresy and slowly stomp around the battlefield. He occasionally kneel and fire fast travelling orbs in 8 directions.

Aftermath
After the fight is over the Moon will begin a detonation sequence. The player has 4 minutes to get back to the start of the level in order to escape. Sporadically, lines of flames will appear. Void Reavers will also spawn and attack the player.
