White Shadow Soul Temper: Is Deepening Frost Worth It?

Whiteshadow — the frost blade taken from the Blizzard Blademaster behind the Four Guardians’ Mirror — has exactly one Soul Temper option in Phantom Blade Zero: Deepening Frost. Tempering is irreversible and charges the material plus a flat 5,000 Remnant Dust. The question here is short: does a single line of text justify the fee? Usually yes. This page covers what the temper changes, the four-piece material hunt, and the honest caveats. For the blade’s base kit, see the Whiteshadow weapon guide; for cross-weapon rankings, the best Soul Tempers tier list.

What Does Deepening Frost Actually Change?

Base Whiteshadow already pressures guards better than most elemental weapons: every hit inflicts Chill and builds the enemy’s Frozen Gauge; a full gauge freezes the target solid. Frost Strike (block + Sha-Chi attack) imbues the blade so the next attack greatly builds the gauge, Frost Convergence refunds Sha-Chi when it lands, and the White Shadow’s Frosthowl Power Surge guarantees a freeze on everything it catches. The one counterplay shielded enemies had was simply blocking: chip damage, no gauge, no freeze.

Deepening Frost, verbatim from Game8’s skill table:

Attacks still build the enemy’s Frozen Gauge even when blocked.

One line that deletes the counter. Shield-bearers — the Mandate soldiers who stall every other frost plan — now freeze behind their own shields, and Frostspike Finisher turns each freeze into a gap-closing damage window. The temper is a mechanic patch, not a number patch: it guarantees the weapon’s loop (hit → gauge → freeze → finisher) never dead-ends on a block.

Material Route: Boy’s Worn Outfit in the Phantom Illusionist Ruins

The temper material is Boy’s Worn Outfit, a four-piece set assembled in the Phantom Illusionist Ruins — the Discordance realm reached through the Four Guardians’ Mirror on Meigu Lake’s frozen western shore, the same road that ends at the Blizzard Blademaster. Reaching the realm at all still requires the four Acolyte Masks from the hidden Acolyte bosses — the same gate as the Whiteshadow weapon itself — so plan one circuit, not two. Per GameRant and KeenGamer’s material tables, the four pieces:

1. Boy’s Shoes — continue past the multi-slide descent and collect them on the lower route.
2. Boy’s Cap — fight the enemy on the rooftop near the broken ship, then collect the cap.
3. Boy’s Trousers — follow the snowy path to the hut containing them.
4. Boy’s Shirt — find it after reaching the fourth Bell of the realm.

Assemble all four and the outfit becomes the temper material. The route doubles as the epilogue to the Whiteshadow story: the same ruins host the six Blizzard Blademaster Memory Flowers of the Whiteshadow quest, so one sweep can finish the flower hunt, bank its +10% max HP reward, and collect your temper material in a single trip. No vendor stocks the outfit — the Soul Temper materials index traces it to this single realm.

Game-Changer or Dust Trap? The Cross-Evaluation

One caveat stays honest: bosses resist the freeze itself far longer than regular enemies, so against them Deepening Frost is a pressure tool — it keeps the gauge climbing through their blocks — rather than a freeze guarantee. Pair it with the Acolyte Icicle accessory, per TheGamer’s weapon ranking, and the buildup rate compounds until you can zip between frozen targets.

How to Temper Whiteshadow

Soul Tempering unlocks after meeting Myst in the Order’s underground tavern in Pangzhen during Chapter 4. At any Bell, open the equipment upgrade menu, select Whiteshadow, and confirm — Boy’s Worn Outfit plus 5,000 Remnant Dust, consumed immediately and irreversibly. Read the Soul Tempering system guide before you commit, and if the Dust fee collides with other tempers, the Remnant Dust farming routes cover the fastest loops.

The Verdict

Deepening Frost is a game-changer for anyone who mains the frost blade — it converts Whiteshadow from “strong until someone raises a shield” into a countdown no guard can pause. Even the material route is efficient, piggybacking on the memory-flower sweep you were likely already doing in the same realm. Temper it the moment the outfit is assembled; the only reason to wait is if Whiteshadow itself is still sitting in storage.

FAQ

Which temper is best for Whiteshadow?

Deepening Frost — it is the only temper, and it earns the slot: blocked attacks keep building the Frozen Gauge, removing the block as an answer to the whole weapon.

Is the Whiteshadow soul temper worth 5,000 Remnant Dust?

Yes for frost mains; the blocked-hit clause is the difference between a stalled fight and a frozen one. Hold the outfit only if the blade stays benched.

What does Deepening Frost do exactly?

Attacks still build the enemy’s Frozen Gauge even when blocked. A full gauge freezes the target solid, and Frostspike Finisher dashes to frozen enemies for bonus damage.

How do you get Boy’s Worn Outfit?

Collect Boy’s Shoes, Boy’s Cap, Boy’s Trousers, and Boy’s Shirt inside the Phantom Illusionist Ruins behind the Four Guardians’ Mirror on Meigu Lake, then assemble them into the temper material.
