Transmutations Guide

Transmutations are Pass the Fear’s elemental proc layer — status effects that trigger off weapon tags, relics, tarot, and sub-weapon synergies. Mastering them separates mid-run clears from Dual Element ceiling runs. This guide explains the core transmutation types, how buildup speed works, and which affixes accelerate each outcome without spoiling hidden puzzle content.

Core transmutation types

Community databases and launch guides verify five primary transmutation families at full release:

Transmutation	Role	Build hook
Hemorrhage	DoT bleed stacking	Sustained fire routes, on-hit volume
Freeze	Control + shatter windows	Frost barrels, Shatter affix timing
Disruption	Stagger and interrupt	CC chains before boss phase shifts
Corrosion	Armor shred / resistance bypass	Long fights vs elite shield layers
Ignition	Burst burn spikes	Fire proc chains, air-bullet explosions

Dual-element relics and full-release Charge Weapon lines can apply two families on one trigger window — the backbone of Dual Element builds.

Buildup vs direct triggers

Transmutations arrive through two paths:

1. Buildup — apply stacks until a threshold detonates (freeze shatter, corrosion break). Rewards Fireworks Master volume or sustained beam weapons.
2. Direct triggers — relics, tarot, or affixes that force a transmutation on crit, Final Shot, or Embarkation room entry. Rewards One-Shot Nuke timing.

Misaligned paths waste slots: a buildup freeze relic on a one-shot charge primary that never stacks frost will underperform a generic damage trinket.

Tarot and Mythic synergies

Tarot treats upright and reversed cards as 44 distinct effects. Transmutation builds often chase:

• The Moon (Reversed) — strong transmutation and elemental scaling; pairs with dual-status relics.
• The Moon (Upright) — chance to re-trigger sub-weapon transmutation; rewards two-slot planning from weapon customization.
• Five-Color Supreme Ring (Mythic) — chain reactions across elements; see Forge guide.

Never assume reversed is strictly stronger — some upright Moon lines beat reversed on short Reality routes.

Co-op transmutation roles

Four-player parties split transmutation duties cleanly:

• Applicator — frost or disruption primaries tagging elites for the squad.
• Detonator — Shatter or Final Shot secondaries consuming setup windows.
• Aura / relic carrier — dual-element mythic holders who cannot swap without losing party-wide procs.
• Frontline — Iron Bucket Knight holding aggro while applicators stack safely.

Call out when your tags expire — silent desync is why co-op transmutation runs feel “RNG broken” when communication fails. Read team roles for voice check macros.

Difficulty and Pearl interactions

Blood Moon and Pearl modifiers that restrict skills still allow shooting and reloading after patch 7.27 Silence tweaks — transmutation weapon-based routes remain viable when ability spam builds collapse.

Chaos Battle Scar scars that buff enemy armor push Corrosion and Disruption value over raw Ignition burst.

Practical framework per run phase

Early run: pick one transmutation family matching your barrel drop — do not split fire and frost before slot ten is mapped.

Mid run: add a sub-weapon or relic that detonates your chosen family (Shatter for freeze, Hemorrhage amplifiers for bleed).

Late run / bosses: swap to direct-trigger tarot or Final Shot lines if buildup windows are too short for phase timers — boss guide lists tell windows per chapter.

Use the affix reference tool to filter tags that mention transmutation, Embarkation, or Shatter before committing Forge rerolls.

Transmutations are readable once you name your family, pick buildup or direct triggers, and assign co-op roles. Random elemental barrels without a plan still clear Normal — they rarely clear Blood Moon with Pearls enabled.
