Tips

 * Mithrix will begin to slowly pace towards the player once he's sufficiently weakened in his final phase. This makes him much easier to line up.


 * It is best to avoid collecting items that deal damaging effects that are beyond the players control, such as items that inflict damaging debuffs such as Bleeding.
 * This extends to offensive Drones and other summoned allies as well.


 * Certain Artifacts can greatly help:
 * The Artifact of Command allows one to stack items that affect the damage of the Beacon itself, like Armor-Piercing Rounds or Crowbars.
 * The Artifact of Swarms halves the health of Mithrix and provides two of him to kill if something goes awry.
 * The Artifact of Glass greatly increases the damage of your abilities, but opens up the certain possibility of getting one-shot by Mithrix' abilities.


 * Coordinating with an Artificer's Snapfreeze ability can open up the opportunity to hit Mithrix with some breathing room.
