Description[]

Mithrix is an ancient, cyclopian humanoid with godlike powers, much of which he shared with his brother Providence. The growing philosophical opposition between the two siblings worsened to the point that Mithrix was banished to the shattered pieces of Mithrix (14) CommencementMithrix (15)Commencement (Final)

Skills & Encounter[]

During phases 1 and 3 of the fight, Mithrix has the adaptive armor passive and unique scaling. These two aspects make him extremely tanky compared to other enemies due to increased health and armor boost.

Boss Encounter[]

Phase 1[]

Mithrix starts the battle with basic attacks, running towards the player to get into melee range.

Primary: Hammer Smash/Needle Barrage[]

This skill has two modes depending on whether Mithrix is running or not.

If Mithrix is not running, he can use Hammer Smash, where he stops and winds up to smash the ground with his hammer. A direct hit from the hammer's path deals 1200% with a proc coefficient of 1.0. As the hammer hits the ground, it creates an explosion also dealing 1200% damage with a proc coefficient of 1.0 in a radius of 12m with linear falloff. The combination of both sources of damage can kill the player though one-shot protection if the first hit doesn't trigger OSP, but if the first does trigger OSP, the blast will not damage the player as it occurs in less than 0.1s from when OSP has been triggered.

The attack lasts for 4 seconds, during which Mithrix is open to attacks. However, attack speed affects the animation of the wind up and how quickly the smash will occur from the moment the skill is activated.

This skill has a cooldown of 4 seconds.

If Mithrix is sprinting instead, he can fire up to 12 homing needles moving at 120m/s. Each needle explodes upon impact dealing 60% damage with a proc coefficient of 1.0 in a radius of 2m with no falloff.

This skill has a cooldown of 6 seconds, which begins after the first needle is fired. Once the skill has come off cooldown, it will replenish all 12 stocks regardless of how many have been used.

If Mithrix toggles sprinting while the skill is on cooldown so that it switches to Hammer Smash and back, all charges will be replenished immediately.

Secondary: Hammer Swing[]

Mithrix swipes with his hammer, dealing 200% damage with a proc coefficient of 1.0 while pushing the target away. This attack moves him forwards a moderate amount.

This skill has a cooldown of 5 seconds and the attack animation lasts for 4 seconds which scales with attack speed.

Utility: Dash[]

Mithrix dashes a short distance forward, backward, left, or right for 0.3 seconds. This also removes all his timed debuffs, but not any damage-over-time effects.

This skill has a cooldown of 3 seconds and holds 2 charges.

Special: Shock Wave[]

Mithrix bends down to jump high into the air, which he does after 1 second (scales with attack speed). After 3 seconds he slams down in the center of the arena, creating a ring-shaped shockwave consisting of 12 waves that travel outwards at 60m/s for 3 seconds. The shock wave effectively ends when it reaches the thin line of rocks between the platform where he is first seen. Each wave deals 400% with a proc coefficient of 1.0 and inflicts Mithrix (26) CrippleMithrix (27)Cripple (Debuff)

This skill has a cooldown of 30 seconds.

Behaviors[]

  1. Use special (Shock Wave): Mithrix must have less than 75% health.
  2. Use utility and strafe: Mithrix must be within 40m from its target, This behavior cannot be selected twice in a row. If this behavior is selected as Mithrix is approaching the player, it will very likely be followed up by either his primary or secondary skill. This can look like strafing out of the way of a possible incoming attack and then attacking from the flank.
  3. Use utility: Mithrix must be within 40-50m from its target. This behavior cannot be selected twice in a row.
  4. Use secondary: Mithrix must be within 40m from its target.
  5. Use primary (Hammer Smash): Mithrix must be within 35m from its target.
  6. Sprint and use primary (Needle Barrage): Mithrix must be more than 70m away from its target, have line of sight, and have less than 80% health. Mithrix will ignore the node graph and run directly towards the target. This behavior is active for 2 seconds.
  7. Chase off nodegraph: Mithix must be within 50m from its target and have line of sight. This behavior is active for 2 seconds and will most likely be selected when Mithrix is near the target after both the primary and secondary are on cooldown.
  8. Sprint off nodegraph: Mithrix must be more than 50m away from its target. This behavior is active for 1 second.
  9. Chase: no requirements.

Phase 2[]

Mithrix leaves the arena, and several stone pillars rise up around the arena. In place of Mithrix himself, 2 Mithrix (42) Lunar Chimera GolemsMithrix (43)Lunar Chimera (Golem)

Lunar enemies spawning by a Combat Director as time goes on. All spawned enemies must be defeated to complete this phase.

Phase 3[]

Mithrix returns with his hammer glowing blue and some of his attacks are now upgraded. Lunar enemies will also continue spawning occasionally.

Primary: Lunar Hammer Smash/Needle Barrage[]

Mithrix's Hammer Smash is now energized and upon explosion it will create two additional effects. 3 small shock waves are sent forward, similar to those from his Shock Wave skill. These deal 200% with a proc coefficient of 1.0 and also inflict Cripple.

A lingering pillar of blue flame is also created at the hammer's point of impact, which deals 75% damage with a proc coefficient of 0.2 and ticks 6 times per second for 45 seconds. These pillars are 40m tall and can go through terrain. This means that if the player is on top of a ramp on the outer areas of the arena and Mithrix smashes the ground underneath, the pillar can go through the ramp's ceiling and damage the player. These pillars can also be blocked by Defensive Microbots.

Special: Shock Wave/Big Spinny[]

After Mithrix performs his Shock Wave leap, his special skill is replaced by a new one which becomes available after a cooldown of 8 seconds. Once this new skill has been activated, it will revert back to Shock Wave.

With this new skill Mithrix creates 9 pillars that rotate either clockwise or anticlockwise. After 3 seconds they deal damage on the spot for 900% damage with a proc coefficient of 1.0 and also inflict Cripple. Mithrix will execute this attack 5 times in a row, with each time the rotation being random.

Behaviors[]

Mithrix behaves the same away as in Phase 1, but he has one new behavior that supersedes every other in terms of priority for his new special attack.

  1. Use special (Big Spinny): Mithrix must have less than 80% health. In theory this will always be selected when the skill comes off cooldown after Shock Wave, since the latter requires less than 75% health to be used. However, if Mithrix has healing items from the Mithrix (52)Artifact of Evolution, it is possible to use Shock Wave after having less than 75% health, but then recover to more than 80% before Big Spinny comes off cooldown.

Phase 4[]

Mithrix appears at the center of the arena and looks weakened with his armor broken and his hammer gone. He starts by stealing all players' and their allies' items, during which time he is invulnerable. Damaging him will release the items. See the Notes section for more details of how this works.

The stealing of the player's items can be skipped if Mithrix takes damage in the first frame of the phase. This is due to his invulnerability being applied after a short window, and not being present on spawn. This is most easily done with continuous damage, most notably a Mithrix (53) Kjaro's BandMithrix (54)Mithrix (55)Kjaro's Band
High damage hits also blasts enemies with a runic flame tornado. Recharges over time.

Hits that deal more than 400% damage also blasts enemies with a runic flame tornado, dealing 300% (+300% per stack) TOTAL damage over time. Recharges every 10 seconds.
triggered in the center of the arena (which may occur when Mithrix's phase 3 is finished after his jump slam). This will leave Mithrix with no items, and the player with all of their items, resulting in a quick completion of this phase.

Mithrix moves much slower than in the previous phases, slowly stomping around the arena and using exclusively ranged attacks. While his base damage is also weaker, the use of the stolen items can cause devastation. His HP is governed by a different formula and since he no longer has unique scaling, his max HP will be significantly lower. Any single instance of damage that deals more than 30% of his health will also stagger him. If the player has any Halcyon Seeds, Mithrix (56) AurelioniteMithrix (57)Aurelionite

will spawn and help the player during this phase.

There is a bug in which Mithrix will give the player Tonic Afflictions without either of them previously having any.

Primary: Needle Burst[]

Similar to his needle attack from the previous phases, but there is less spread.

Secondary: Lunar Orbs[]

Mithrix kneels and pounds the ground, creating a blast that deals 600% damage with a proc coefficient of 1.0 in a radius of 12m with linear falloff. This also creates a ring of 8 orbs that spiral outwards, converge back into the center and then spiral out again. Upon impact they deal 400% damage with a proc coefficient of 1.0 in a radius of 6m with linear falloff. Their lifetime is 9s (plus a random 0.0-0.3 second offset), after which they will explode on the spot, so players should avoid being near them at that point.

Mithrix also deals 8% of his current health as non-lethal damage to himself.

This skill has an animation duration of 6 seconds which scales with attack speed.

This skill has a cooldown of 8 seconds, which does not start until the attack has finished.

Behaviors[]

  1. Use secondary: Mithrix must be within 180m from its target and have less than 90% health.
  2. Use primary: no requirements as long as the skill is off cooldown.
  3. Chase: no requirements.

Aftermath[]

Once Mithrix is defeated, all stolen items are returned and the moon begins a detonation sequence with an on-screen countdown. In order to exit Mithrix's arena, the surviving players must jump into one of the floating portals in order to teleport out. The players have 3 minutes to get to the Rescue Ship and complete its holdout event in order to escape, which requires the players to protect the ship by staying near it for 1 minute. Lines of flames will appear all across the map, similar to the columns used by some of Mithrix's attacks. Mithrix (58) Void ReaversMithrix (59)Void Reaver

Arena Escape Portals[]

Mithrix (72)

5 out of the 12 escape portals will randomly spawn, each with their own predefined teleport destination. They all rotate either clockwise or anticlockwise around the center of the arena at fixed radii lengths and heights. To identify them correctly, look for a big giant rock floating outside the arena and turn 180°. With your back against the reference point, the image below shows all the portals at the initial position they spawn and the direction they travel.

Mithrix (73)

The teleport location and distance from the dropship for each escape portal is:

  1. On the bridge between the two Pillars of Design islands, 883.3 m away.
  2. In the middle of the Pillars of Blood area, 994.4 m away.
  3. On the far top floor of the Pillars of Soul area, 567.3 m away.
  4. On the back right of the Pillars of Blood area, 1022.9 m away.
  5. On the Cauldron island, 863.4 m away.
  6. On the Cauldron island near the chains towards the Pillars of Mass, 763.8 m away.
  7. On the ground floor or the Pillars of Soul area, 472.7 m away.
  8. On the Pillars of Design area, close to the center pillar leading to Mithrix, 736.3 m away.
  9. On the Pillars of Design area without the cauldrons, 874.2 m away.
  10. On the Pillars of Design area, very close to the center pillar leading to Mithrix, 721.1 m away.
  11. On the back left of the Pillars of Blood area, 1109.2 m away.
  12. On the far back of the Pillars of Blood area, 1058.8 m away.

Notes[]

  • Mithrix steals items in two phases. In the first phase he steals an item from every player and their minions every 0.2 seconds for 9 seconds. In the second phase he steals an item every 0.1 second until all have been stolen. Due to frame rounding, in phase 1 he ends up stealing every 0.21666 seconds. Since the first item takes 1 second to reach Mithrix, he effectively registers 37 items from each entity at the end of phase 1.
    • While Mithrix steals items from minions, there is no visual effect of the item transfer.
  • Mithrix will only use items stolen during the first phase, excluding all items from minions and any items in the AIBlacklist and BrotherBlacklist categories. As items are returned, it will be those from phase 1 first, even if Mithrix is not using them himself.
    • This means that if a player has 50 items, Mithrix will use any allowed items in 14-50. The items will be returned in the order 14-50, 1-13.
    • While in single player Mithrix can use up to 37 items, in multiplayer this is very likely to be higher unless each player's last 37 items are the same.
  • Mithrix cannot steal items from the CannotSteal category. This also includes untiered items that are used for game mechanics, including AdaptiveArmor, BoostAttackSpeed, BoostDamage, BoostEquipmentRecharge, BoostHp, ConvertCritChanceToCritDamage, CutHp, DrizzlePlayerHelper, DroneWeaponsBoost, DroneWeaponsDisplay1, DroneWeaponsDisplay2, ExtraLifeConsumed, ExtraLifeVoidConsumed, FragileDamageBonusConsumed, Ghost, GummyCloneIdentifier, HealingPotionConsumed, HealthDecay, InvadingDoppelganger, MageAttunement, MinHealthPercentage, MinionLeash, MonsoonPlayerHelper, SkullCounter, TeamSizeDamageBonus, TeleportWhenOob, TonicAffliction, UseAmbientLevel, VoidmanPassiveItem.
  • While Mithrix steals all items from players and minions, the accumulated damage threshold for returning an item is only the sum of items stolen during the first phase and only from players.
    • For example, for two players this will be up to 1/74 of his max health per item. Note that this percentage is capped at 1/100.
    • The items are returned one by one in the order they were obtained. In multiplayer, the items will be returned to players in round robin order, by player slot.
    • The accumulated damage received is not decreased when Mithrix recovers health either from healing or shield recharging.
  • Upon fully charging the Rescue Ship and beating the game, all players (dead or alive) will be awarded Mithrix (74) 10 lunar coins.

  • Mithrix cannot climb the pillars that appear on Phase 2, so if the player gets on top of them and uses ranged attacks, Phase 3 and 4 will be very easy. The ranged attack on Phases 3 and 4 can be easily dodged from higher ground as well. HOWEVER, the lines of flame in Phase 3 can still hit the player.

Lore[]

They knew to stay away from the wells - but they were just kids. And they just wanted to know.They threw in dirt and stone and kifruit and starseed, watching as they collapsed. Thorp! The gravity wells would swallow up anything. Glass and mud and silver. Wind. Heat. Pulsar radiation.And when his brother wasn’t watching, Mithrix would throw in worms. Thorp! But only when he wasn’t watching. You see, his brother loved worms. It would make him sad. But Mithrix didn’t care much about worms. He was just curious.But one time, his brother was watching. And his brother loved worms.

Trivia[]

  • There is an unused introduction to the fight where Mithrix spawns sitting on a throne instead of dropping in from the sky.
  • The Hammer Smash is conditionally set to be the primary skill if Mithrix is not sprinting or is grounded. This means that if Mithrix sprints, so that the skill switches to Needle Barrage, but then jumps, the skill will switch back to Hammer Smash upon landing even if Mithrix is still sprinting.
  • In the code there is an unused idea when Mithrix uses his Shock Wave on Phase 3, where he spawns an undetermined number of glass-looking copies of himself that last for 20 seconds, have much lower stats and can only use the secondary skill. As it currently stands, 0 such copies spawn.
  • Shock Wave actually holds 5 charges and requires all 5 to activate the skill. After coming off cooldown all 5 charges will be replenished. Mithrix would need 5 Mithrix (157)Mithrix (158)Survivors of the Void - DLC Content

    Add +1 (+1 per stack) charge of your Special skill. Reduces Special skill cooldown by 33%. Corrupts all Fuel Cells.
    in order to be able to use the skill twice in a row. But the cooldown would still replenish only 5 charges at a time.
    • On Phase 3 after activating the skill once, it would switch to Big Spinny and each Lysate Cell would grant an extra charge. However, upon using this once, it would revert back to Shock Wave regardless of how many charges it had remaining.
    • Mithrix’s theme is "You're Gonna Need a Bigger Ukulele."
  • While Hammer Smash and Hammer Swing have long end lag delays, it is possible to use the Dash to cancel them and regain control much faster. If Mithrix is in close range and has at least 1 Dash charge, he can use both skills in quick succession.
  • Mithrix on Phase 4 still retains his Dash and Shock Wave skills, but he is not programmed to use them.
  • The Big Spinny flame walls extend outwards for 300m. The arena is big enough that if Mithrix is executing the attack near the edges, the walls will not reach the opposite side.
  • The blue flame wall attacks that occur during the aftermath of the fight are actually executed by a hidden character called "BrotherHaunt". Brother is the internal name for Mithrix.
  • Any one of Mithrix’s three encounters have the chance to drop his Logbook.
  • When Mithrix steals the player's items on phase 4, he will gain spikes on parts of his body colored by the type of item he steals, for example uncommon items would give him green spikes:
