Silver Palace — Shop & Exchange Guide

The Argent Docks works as the central commercial hub of Silver Palace. Nearly every progression material and gacha currency earned through investigations, combat commissions, and Revelations is redeemed here.

Running down the left rail of the screen are 4 primary shop tabs. Silver Palace utilizes 6 distinct currencies distributed across these tabs. Each currency is strictly locked to its designated tab or sub-tab, preventing accidental misallocation or spending errors.

As covered in our Gacha Guide, players don't spend Reactor Crystals directly on the banner interface. Instead, the Cognito Reload terminal converts Reactor Crystals into any of the four designated Shot ammunition types at a flat rate of 360 Reactor Crystals per Shot with zero stock limitations:

• Judgement Shot: Summoning ammunition for the Limited-Time Repertoire (Featured Character Banner).
• Deduction Shot: Summoning ammunition for the Limited-Time Monologue (Featured Motive Banner).
• Standard Shot: Summoning ammunition for the Standard Repertoire (Standard Character Banner).
• Bullet of Insight: Summoning ammunition for the Standard Monologue (Standard Motive Banner).

Pro-Tip: Always buy Shots on demand when ready to summon rather than pre-converting Crystals, ensuring total flexibility across upcoming banner schedules.

Cognito Assembly works as the reclamation exchange where players spend cashback currencies accumulated from Revelation summons. It's partitioned into two specialized sub-tabs:

The Shard Exchange (Spend Mind Shards Here)

You accrue Mind Shards whenever pulling a 4-Star or 5-Star Character or Motive (20 Mind Shards for your first copy and first 6 duplicates of a 5-Star, and 50 Mind Shards from the 7th duplicate onward).

• All 4 Revelation Shots: Cost 12 Mind Shards each with zero buy caps. Because 12 Mind Shards equals 360 Reactor Crystals, each individual Mind Shard possesses an effective value of 30 Reactor Crystals—rendering this the highest pull value in the entire shop.
• Character-Specific "Mystery" Motives (4 Titles): Cost 90 Mind Shards each, capped at 2 purchases per title.

The Mind Grain Exchange (Spend Mind Grains Here)

You receive 8 Mind Grains every time a 3-Star Motive appears in your summons. Every listing in the Mind Grain Exchange features a weekly stock limitation:

• All 4 Revelation Shots: Cost 50 Mind Grains each, capped at 5 per week per Shot type. (Note: Buying a Shot here's substantially more expensive relative to drop income than the 12-Shard price next door; prioritize upgrade resources first).
• The Science of All Things (Character EXP Books): Packaged in bundles of 20 across four tiered volumes priced at 10, 25, 50, and 110 Mind Grains.
• Motive Bookmarks (Motive EXP Materials): Sold in bundles of 20 across four tiers (topped by the Crystal Bookmark of Provenance) priced at 10, 25, 50, and 110 Mind Grains.
• Rectified Concentrates (7 Lines): Elemental ascension materials matching each of the 7 Reactor Attributes.
• Ounce Bundles: Direct currency packages to reinforce your upgrade reserves.

The Gift Shop stocks all 18 giftable Valuables used to advance your operatives' Trust (affinity level).

Price & Stock Allocation

Every gift item costs a flat 10,000 Ounce with a weekly stock allowance of 50 units.

How Trust Works

Each character possesses 5 Trust levels requiring a cumulative total of 780 Trust EXP. Operatives favor 2 or 3 specific gifts from the 18 stocked items; presenting a preferred gift grants 100 Trust EXP.

Total Cost to Max a Character

Gifting 8 preferred Valuables (80,000 Ounce total) completely maxes an operative's Trust, unlocking substantial account rewards:

• Bonus Ounce packages and Insight literature.
• A personalized character letter.
• Permanent Companionship mode.
• Exclusive Interaction and Rendezvous scenes.

Exclusive Signature Gifts

While most catalog gifts are shared among two or three operatives, 4 signature gifts are exclusive to a single character:

The Epiphany Archive eliminates random drop frustration by transforming gear acquisition into a deterministic shop system. It's structured into three dedicated sections:

1. Literary Works (14 Titles) & 2. Beginner Readers (16 Titles)

• Currency: Fate Clippings (earned by salvaging unwanted Epiphanies and conquering Hilbert's Hotel).
• Flat Price: Every single one of the 30 Epiphany titles costs a flat 1,000 Fate Clippings. Rather than grinding open-world bosses endlessly, detectives can dismantle surplus drops and buy the exact best-in-slot Epiphany piece required.

3. The Stationery Section (Addendum Inks)

This is the sole shop department that transacts in Surplus Materials. It stocks the two specialized inks used to engrave powerful Addendum passive traits onto your Epiphanies:

• Sketch Ink: Costs 600 Surplus Materials (rolls an unconstrained, randomized Addendum trait).
• Custom Ink: Costs 3,000 Surplus Materials (combined with 1 Sketch Ink to execute a targeted Addendum roll locked to a specific character).

To optimize account power and prevent resource starvation, follow this proven spending hierarchy across the Argent Docks:

• 1. Commit Mind Shards to Uncapped Shots First: At 12 Mind Shards per ticket, the Shard Exchange is the most efficient conversion rate in the game. Only spend 90 Mind Shards on a 4-Star Mystery Motive if your squad's primary carry desperately requires that specific weapon.
• 2. Match Mind Grain Books & Bookmarks to Squad Level: Avoid blindly buying 110-Grain top-tier materials early on. Buy the volume tier that matches your squad's active level cap, and only get Rectified Concentrates for the Reactor Attributes deployed in your combat team.
• 3. Reserve Custom Ink for Your Main Carry: Because Custom Ink costs 5x more than Sketch Ink (3,000 vs. 600 Surplus Materials), restrict Custom Ink strictly to your primary DPS operative's Lv. 60 or 70 Epiphany.
• 4. Buy Gifts With Ounce Last: Ascending characters and Motives requires more than 6.1 million Ounce across an active roster. Only allocate 80,000 Ounce for Gift Shop Valuables once your main squad's combat talents and equipment are fully amplified.
