If you’ve reached the point where Mythic Relics start appearing in Pass the Fear, you’ve probably noticed they’re on a completely different level compared to ordinary relics. These aren’t simple stat boosts—they can completely change how your build works. Some reward stacking mechanics, others make you nearly impossible to kill, and a few can even become the centrepiece of an entire run.
I’ve found that Mythic Relics are usually the ones that make you rethink your build. Instead of asking, “Which relic gives more damage?” you start asking, “How do I build around this relic?” That’s where they really shine.
Below you’ll find every Mythic Relic currently available, along with what each one does and which builds benefit the most.
Mask of Slaughter
Effects
- Physical Damage +100%
- When entering a stage, the first Physical Relic you dismantle permanently grants its effects (Unique Passive).
Mask of Slaughter is one of the strongest relics for Physical builds. Besides doubling your Physical Damage, it lets you permanently absorb the effect of another Physical Relic after dismantling it.
This means weaker Physical relics don’t necessarily become useless. Instead, they can permanently strengthen your build without taking up an inventory slot.
Best For
- Physical damage builds
- Marcus weapon builds
- Long runs with multiple relic choices
Unbreakable Bulwark
Effects
- Grants 8 Armor at Embarkation and every Destination.
- Damage taken cannot exceed your current Armor stacks.
- Armor limit increased by 1000.
- Armor gained is increased by 100%.
If your goal is staying alive, Unbreakable Bulwark is one of the best defensive Mythic Relics in the game.
It doesn’t just give Armor—it dramatically increases both your maximum Armor and the amount you generate. Since incoming damage is capped by your Armor stacks, this relic becomes incredibly valuable during difficult encounters.
Best For
- Tank builds
- High-difficulty runs
- Co-op survivability
Thunder Armor
Effects
- Using your Ultimate refunds 50% of the Ultimate Gauge.
- Activating your Ultimate grants complete damage immunity for 2 seconds.
Thunder Armor rewards aggressive Ultimate usage.
Every Ultimate becomes both an offensive and defensive tool. Besides recovering half your Ultimate meter, you also gain a brief period of complete invulnerability, allowing you to survive dangerous attacks or continue dealing damage safely.
Best For
- Frequent Ultimate builds
- Boss encounters
- High-risk gameplay
Endless Firewood
Effects
- Grants 100 Ember stacks when carried.
- Ember limit increased by 1000.
- Every Destination grants Ember equal to 5% of your current stacks.
- Shattering permanently grants 30 Ember.
This relic revolves entirely around Ember stacking.
The more Ember you accumulate, the stronger future rewards become because every destination increases your current total by a percentage rather than a fixed amount.
It scales exceptionally well during longer runs.
Best For
- Ember-focused builds
- Long progression runs
- Scaling damage builds
Throat of the Hydra
Effects
- Grants 100 Growth stacks when carried.
- Growth limit increased by 1000.
- Every Destination grants Growth equal to 5% of current stacks.
- Shattering permanently grants 30 Growth.
Throat of the Hydra functions almost identically to Endless Firewood but uses Growth instead of Ember.
Because Growth continually increases throughout a run, this relic becomes stronger the longer you survive.
Best For
- Growth builds
- Scaling strategies
- Extended chapters
Five-Color Supreme Ring
Effects
- Transmutation Damage +150%.
- 5% chance to apply Corrosion, Disruption, Freeze, Ignition, and Hemorrhage in sequence.
- Status effects can trigger one another through additional chain effects.
- Triggering Transmutation deals 150% True Damage.
Five-Color Supreme Ring is arguably one of the most interesting Mythic Relics.
Rather than boosting one damage type, it creates chains of elemental status effects that constantly interact with one another.
Corrosion can trigger Disruption.
Disruption can trigger Hemorrhage.
Hemorrhage can trigger Freeze.
Those reactions continue looping, creating surprisingly powerful elemental combinations.
If your build already focuses on status effects, this relic dramatically increases both consistency and damage output.
Best For
- Elemental builds
- Transmutation damage
- Anomaly-focused Hunters
- Status effect combinations
Forged Mythic Relics
Forged Mythic Relics are upgraded versions of their standard counterparts. Every Forged relic keeps the same core mechanics while significantly increasing its stats and effects.
If you have the opportunity to forge one, it’s almost always worth doing.
Forged Mask of Slaughter
Effects
- Physical Damage +250%.
- Permanently absorbs the first dismantled Physical Relic each stage.
Compared to the normal version, the Physical Damage bonus increases from 100% to 250%, making it one of the highest offensive bonuses available for Physical builds.
Forged Unbreakable Bulwark
Effects
- Grants 10 Armor twice at Embarkation and every Destination.
- Armor limit increased by 2000.
- Armor generation increased by 200%.
- Damage taken cannot exceed Armor stacks.
This version dramatically improves survivability by generating much larger amounts of Armor while doubling your maximum Armor capacity.
Forged Thunder Armor
Effects
- Ultimate refunds 100% of the Ultimate Gauge.
- Grants complete damage immunity for 3 seconds after using your Ultimate.
Instead of recovering only half your Ultimate meter, the Forged version completely refills it while extending the invulnerability duration.
It’s one of the strongest defensive upgrades available for Ultimate-focused builds.
Forged Endless Firewood
Effects
- Grants 200 Ember.
- Ember limit increased by 2000.
- Every Destination grants 10% of current Ember.
- Shattering permanently grants 60 Ember.
Every value is effectively doubled, allowing Ember builds to scale much faster during long runs.
Forged Throat of the Hydra
Effects
- Grants 200 Growth.
- Growth limit increased by 2000.
- Every Destination grants 10% Growth.
- Shattering permanently grants 60 Growth.
Like Endless Firewood, the Forged version significantly accelerates Growth scaling and is ideal for marathon runs.
Forged Five-Color Supreme Ring
Effects
- Transmutation Damage +300%.
- 10% chance to trigger elemental status chains.
- Chain trigger chances increased to 15%.
- Deals 250% True Damage when dealing damage.
This is a massive improvement over the standard ring.
Not only are elemental effects triggered more often, but the increased True Damage and higher chain chances make it one of the strongest relics for Transmutation and elemental builds.
While every Mythic Relic has its place, some stand out depending on your build:
- Mask of Slaughter is an excellent choice for Physical-focused characters thanks to its permanent relic absorption.
- Unbreakable Bulwark offers incredible survivability and becomes even stronger on higher difficulties.
- Thunder Armor is perfect if your build revolves around frequent Ultimate usage.
- Endless Firewood and Throat of the Hydra are ideal for players who enjoy long, scaling runs built around Ember or Growth.
- Five-Color Supreme Ring is one of the best options for elemental and Transmutation builds because of its powerful chain reactions and True Damage.
If you later obtain the Forged versions, they’re almost always direct upgrades, offering significantly stronger stats while keeping the same mechanics that made the original relics so valuable.
