Heretic of the False Moon

Last updated 2026-06-23

Heretic of the False Moon, Archived as The Doctor, is a Weekly Boss challenge found in False Moon Institute.

Rules

  • Trounce Domains contain unusually powerful opponents. After successfully completing the challenge, you can obtain abundant rewards.
  • Players can complete this domain as many times as they want, but can only collect rewards once per week by using 30 Original Resin to open the Ley Line Blossom for the first three Weekly Bosses, and 60 Original Resin subsequently. Rewards are refreshed with Weekly World Reset.

Ley Line Disorder

  • The Heretic of the False Moon uses the rift from beyond this world to endanger those who oppose him. Step into the rift and eliminate the source of his power to neutralize the threat.
    The authority bestowed by the marrow of the three moons enables the Heretic of the False Moon to bend the world's order and set forth prohibitions. To overcome him, you must abide by these for a short time, or face punishment for defying them.

Rewards

Claiming the Trounce Blossom for Original Resin Original Resin ×60 (or 30 for the first 3 Weekly Boss claims of the week) after defeating the boss offers the following possible rewards:

Abilities

Return of the False Moon
If The Doctor survives a single instance of DMG exceeding 20% of his Max HP, he will increase all RES by 150% for ~3.5s, and quickly recover all of the HP lost to this instance of DMG.
Moonwither Realm
The Doctor will periodically create 3 Moonwither Realms around the arena. As a Moonwither Realm spawns, The Doctor will command a Moon Replica Shade to unleash a flurry of attacks at its location, dealing 200% Level Multiplier ×4 as Cryo DMG. Each Moonwither Realm will then gradually expand over the next ~20s, up to a radius of 10m. Characters within a Moonwither Realm will have their Movement SPD reduced by 40%. Moonwither Realms will also periodically release pulses around themselves, with DMG and frequency increasing over time.
  • Upon Spawning: Deals 150% Level Multiplier as Cryo DMG every 3 seconds.
  • 9s After Spawning: A rift spawns at the center of the Moonwither Realm.
  • 15s After Spawning: Deals 300% Level Multiplier as Cryo DMG every 1.5 seconds.
  • 20s After Spawning: Radius reaches 10m, expansion stops.
  • 45s After Spawning: Deals 450% Level Multiplier as Cryo DMG every 0.5 seconds.
After a rift spawns, the player may interact with it to enter an alternate dimension. 3 Moon Replica Shades will be present in this dimension. Defeating each Moon Replica Shade will remove the corresponding Moonwither Realm in the main arena, cause The Doctor to lose 8% of his Max HP, and reset the party's Elemental Skill and Elemental Burst cooldowns. In this dimension, laser beams will move across the area, dealing 80% Level Multiplier as Electro DMG on contact. The player will return the main arena after defeating all 3 Moon Replica Shades, but they may also do so early by approaching the exit. While in the alternate dimension, the player is safe from any attacks that occur in the main arena, including Moonfall Impact.

Note that unlike most attacks that scale with Level Multiplier, the attacks described above do not ignore DEF.
Authority of the Three Moons
The Doctor will periodically command the authority bestowed by the marrow of the three moons, setting forth one of the following effects for ~6s:
  • Iridescent Moon: Characters may not face The Doctor.
  • Frost Moon: Characters may not move long distances.
  • Eternal Moon: Characters' movement controls are inverted.
If a character violates the Iridescent Moon/Frost Moon prohibition, The Doctor will drain the entire team's Energy and Special Energy, then attempt to trap a player with a mechanism above them. If successfully trapped, the mechanism will deal 10% ATK ×4 + 50% ATK as Cryo DMG. If the Iridescent Moon/Frost Moon prohibition is not violated during its duration, or after the Eternal Moon effect concludes, the entire team will fully recover their Energy and Special Energy.
Moonfall Impact
This attack is used immediately as the boss fight begins, and repeated once every ~150s. The Doctor will rise into the air, increasing all RES by 200%, as 3 Ancient Moon's Remnants descend from the sky, each dealing 10% ATK as Physical DMG upon landing, then continuously recover Energy and Special Energy for characters standing behind it. The Doctor will then charge up a powerful blast spanning across the entire arena, causing any active characters not located behind an Ancient Moon's Remnant to lose 70% of their Max HP for a total of 4 times at 0.3s intervals. Characters who are initially located behind an Ancient Moon's Remnant but leave before the attack is done will lose its protection and be subject to the remaining attacks from this ability. All HP losses from this attack will bypass i-frames, including HP-locking i-frames from sources like Elemental Bursts.
Falling Remnants
Summons 5 Ancient Moon's Remnants to fall from the sky in succession, each dealing 70% ATK as Physical DMG over a large, marked area.
Replica Attack
If the player is far away, summons 2 Moon Replica Shades to attack the player, each dealing 20% ATK ×3 as Cryo DMG.
Deluge
Summons a torrential downpour across the arena, with each raindrop dealing 20% ATK as Hydro DMG. After some time, reverses the direction of the rain to charge up a massive concentrated blast around The Doctor, dealing 100% ATK as Hydro DMG.
Voltage Discharge
Summons 6 laser beams that move outward from The Doctor in multiple directions, each dealing 20% ATK as Electro DMG on contact. Then, summons two rounds of bolts above the player which strike down after charging, dealing 70% ATK, 80% ATK as Electro DMG respectively.
Sequential Incision
Quickly shifts to the right, leaving 5 emitters in his wake, which each fire a water beam at the player in quick succession, each dealing 20% ATK as Hydro DMG. Follows up with Tidal Trident if the player is close, or Bolt Smash if the player is far away.
Tidal Trident
Fires a charged beam of water in front, followed by two beams of water fired in a "V" shape. Each beam deals 60% ATK as Hydro DMG.
Bolt Strike
Summons a single bolt above the player to strike down, dealing 40% ATK as Electro DMG. If initiated on its own, follows up with Tidal Trident.
Tri-Elemental Combo
Summons a single bolt to strike down at the player, dealing 20% ATK as Electro DMG and releasing 3 laser beams that travel outward, dealing 20% ATK as Electro DMG on contact. Then, performs a single quick slash in front of himself, dealing 40% ATK as Cryo DMG. Finally, fires a charged beam of water in front, dealing 60% ATK as Hydro DMG.

Descriptions

Reviled far and wide as a heretic, The Doctor — Second of the Eleven Fatui Harbingers — has seized the authority of the three moons and now ascends the long steps toward the divine throne of the "new world."
All should have belonged to us.
But reason cast out all that exceeded its limits, leaving humanity blind to its true nature.
Life and death bound us into mortal shells, shackling every spark of aspiration.
Time and space closed in last of all, fencing the mind into meek obedience, so no one would dare imagine breaking free.
From that point on, false gods governed the world, each one declaring their own truth as the sole, unassailable gospel — though none deserved the mantle they so loudly coveted.
There is no inherent structure to life's flow — order was merely imposed upon it. Strip away every shackle laid across this world, and the essence of all things will at last come into view.
And that revelation... is the first light of the new world.
"How much longer will you continue to suffer this stagnant, obsolescent world?"
