Overview

Storage monetization is the most ethically sensitive part of Salt & Steel's business model. The cosmetic shop is philosophically unambiguous — nobody's gameplay is affected by whether they have a painted ship. Storage purchases exist in a grayer space: they are not power, but they are efficiency, and in a game where efficiency has real gameplay value, the line between "saves time" and "provides advantage" deserves careful examination rather than dismissal.

Salt & Steel learns from Path of Exile's stash tab system — both its commercial success and its most valid criticisms. PoE's stash tabs became quasi-essential for engaged players over time, and the requirement of Premium tabs for trade participation created an unambiguous functional gate. PoE's approach was commercially successful but generated sustained community friction that eroded the credibility of the ethical F2P claim.

Salt & Steel's approach is more conservative. The base Cargo Hold is genuinely, not nominally, sufficient for all content. Specialized Holds are organizational improvements, not access gates. And the game's trading system does not require premium storage to participate — trade functionality is free at base.

This document establishes what is sold, why, where the ethical line is drawn, and how to hold it.

The Ethical Line: Organization vs. Gatekeeping

The fundamental design question for storage monetization: are purchases making players more organized, or are they making players who don't buy them less able to engage with the game?

Organization (acceptable): The player can do everything without the purchase. The purchase makes doing those things less frictional, cleaner, and more pleasurable. The player who doesn't buy is not blocked or meaningfully disadvantaged in any gameplay system.

Gatekeeping (not acceptable): The player who doesn't buy encounters real limitations in gameplay engagement. Certain systems become impractical or impossible to engage with at full participation. Economic systems favor buyers over non-buyers in ways that affect character progression.

PoE's Currency Tab falls into a gray zone — without it, currency management is significantly more burdensome, which means currency-farming efficiency is lower, which means character wealth is lower, which means character capability is marginally lower over time. It's not direct power purchase, but the chain of effects is real.

PoE's Premium tab for trading is clearly gatekeeping by this standard — without it, you cannot sell on the primary trade market. Economic participation is gated by payment.

Salt & Steel's storage monetization is designed to stay clearly on the organization side of this line.

The Base Cargo Hold: Genuinely Sufficient

The base Cargo Hold that every captain receives at account creation must be genuinely sufficient for all content progression. Not minimally sufficient — adequately sufficient. A player engaging with multiple game systems simultaneously should be able to make it work with the base Hold.

Base Cargo Hold specifications:

5 general-purpose grid tabs (each 12x12 = 144 item spaces), 720 total spaces
1 dedicated currency compartment (holds all currency types at meaningful quantities — 500 per type minimum — without occupying grid space)
1 automatic chart/map compartment (holds up to 200 nautical charts organized by tier)
Free trade functionality — any item in any tab can be listed for trade without premium upgrade

These are the minimum baseline. The design team must validate these numbers against actual play-test data for players engaging with all available content systems simultaneously before launch. If 5 tabs proves inadequate for typical endgame play, the base allotment is increased before launch, not after.

The validation test: A player engaging with three active content systems (e.g., naval combat, crafting, and the trade economy), completing endgame content at a normal farming pace, should be able to play a full 3-hour session without being forced to town to empty inventory due to storage pressure. If this test fails with base storage, the base is insufficient and must be adjusted.

Cargo Hold Expansions

Additional general-purpose storage tabs, purchased individually or in bundles.

Standard Hold Expansion

Additional 12x12 grid tabs identical in function to the base tabs.

Purpose: More raw storage space for general items
Price: 40–60 Points each ($0.40–$0.60)
Bundle: 4 additional tabs for 175 Points ($1.75)
Cap: A maximum of 20 total general tabs per account (base + purchased). This cap prevents storage from becoming an unlimited wallet and ensures the purchase remains a quality-of-life choice, not an endless accumulation.

Quad Hold

A single tab with a 24x24 grid (576 item spaces — 4x the standard). For players who accumulate items rapidly and want fewer tabs to scan.

Purpose: High-volume storage consolidation
Price: 150 Points ($1.50)
Cap: 4 Quad Holds per account

The Trade-Tab Decision

This is the most important single design decision in Salt & Steel's storage monetization, and it has a clear answer: all tabs are trade-enabled at no additional cost.

A player can list any item for trade from any tab in their Cargo Hold without upgrading to a "premium" version. The in-game trading post works with all base and expanded storage at no additional cost.

This is a direct departure from PoE's model, and it is the right departure. PoE's Premium tab requirement for trade participation is its most valid community criticism. Salt & Steel eliminates this vector entirely. The trading economy is fully accessible to every player from day one regardless of spending history. Economic participation is never gated by payment.

The commercial trade-off: this reduces revenue from the "everyone needs a premium tab" dynamic. This trade-off is accepted. The ethical clarity is worth the revenue differential, and the community trust built by this decision has long-term commercial value that exceeds the short-term revenue loss.

Specialized Holds

Specialized Holds provide category-specific organized storage — dedicated compartments for specific item types that display item quantities, provide sorting and filtering, and reduce the management burden of complex material inventories. They do not increase the quantity of items that can be held in ways that affect gameplay — a player without the Crafting Materials Hold can still accumulate and use every crafting material in the game.

The distinction: Specialized Holds are about finding and counting things efficiently, not about having more things. Every item a specialized Hold accommodates would otherwise fit in a general tab. The Hold's value is organization, not expansion.

Currency Chest

An upgraded currency storage compartment that displays all currency types in a visual grid with quantity counts, supports bulk stacking, provides quick-access filtering, and allows one-click sending of currency directly to crafting interfaces.

What it does: Replaces the base currency compartment with an enhanced version that handles all currency types (including new types introduced in future Voyages) with dedicated display slots, visual quantity at a glance, and faster interface interaction
What it doesn't do: Increase currency held per type above the base compartment; provide any currency that didn't already exist; affect drop rates or currency sources
Price: 75 Points ($0.75)
Base vs. premium difference: The base currency compartment holds 500 per type in a functional but compact interface. The Currency Chest holds 5,000 per type in a visually organized grid with filtering and quick-access functions. The difference is organizational quality and session friction reduction, not capability.

Validation: A player without the Currency Chest should be able to manage their currency meaningfully — checking quantities, making crafting decisions, and engaging in the economy — with the base compartment. This is tested. If the base compartment is found inadequate for typical endgame currency management, the base is improved, not used as a coercive purchase driver.

Chart Chest (Nautical Map Hold)

A dedicated storage compartment for Nautical Charts — the endgame progression maps — that organizes by tier, region, rarity, and applied modifiers. Provides visual quantity display, quick-sort by completion priority, and direct launch interface.

What it does: Replaces the base chart compartment with an interface that handles large chart inventories organized by tier and type, displays modifier information without opening each chart, and integrates with the Voyage planning interface
What it doesn't do: Grant access to charts not earned through gameplay; affect chart drop rates or difficulty; allow charts to be used without completing their prerequisites
Price: 75 Points ($0.75)
Base vs. premium difference: The base chart compartment holds 200 charts in a tier-grouped list. The Chart Chest holds 500+ charts in a fully filterable visual grid. Again: organization, not capability.

Crafting Materials Hold

Dedicated storage for crafting components — the raw materials, processed goods, and reagents used in ship upgrades, gear crafting, and equipment modification.

What it does: Category-organized display for all crafting material types, with quantity tracking, recipe cross-reference (shows which recipes use each material and how many you currently have of required components), and batch transfer to crafting stations
What it doesn't do: Provide crafting materials; affect crafting success rates; allow crafting recipes unavailable through gameplay
Price: 75 Points ($0.75)

Crew Contracts Hold

A dedicated hold for Crew Contracts — the items used to recruit specific crew members with particular skills. Crew Contract management is one of the more administratively complex player activities; this Hold reduces that friction.

What it does: Organizes Crew Contracts by skill type (Gunnery, Navigation, Rigging, Medicine, Combat), displays the key traits and advantages of each contract, and provides filtering by preferred advantage type
What it doesn't do: Provide crew contracts not earned through gameplay; improve crew quality beyond what contracts specify; allow recruitment of crew with better statistics than the contracts hold
Price: 50–75 Points ($0.50–$0.75)

Expedition Hold (Future)

As new Voyage mechanics introduce new item categories (see: PoE's pattern of league mechanics producing new item types), new Specialized Holds will be introduced to accommodate them. Each new Hold follows the same design principle: organization of items that fit in general storage, not expansion of what can be held.

Pricing for new Specialized Holds will be consistent with the existing Hold price range. Holds introduced for Voyage-specific items will remain useful in perpetuity as those Voyage mechanics migrate to the permanent world.

Port Stash Upgrades

Separate from the Cargo Hold (ship-side storage), the Port Stash is on-shore storage accessible when the captain is in port. The Port Stash has different organization priorities — it holds items the captain is not actively carrying but has accumulated over multiple Voyages for long-term use or display.

Base Port Stash

Every captain receives base Port Stash capacity:

3 general storage tabs (12x12 each)
1 cosmetic item vault (all owned cosmetics, regardless of purchase)
1 Account Record archive (Voyage history, reputation records — non-functional storage)

Port Stash Expansion

Additional general Port Stash tabs, at the same price point as Cargo Hold expansions.

Price: 40–60 Points each; 4-tab bundle at 175 Points
Cap: 10 additional Port Stash tabs per account

Voyage Archive Hold

A specialized Port Stash compartment for legacy items from previous Voyages — gear, materials, and records the player is keeping for historical or sentimental value rather than active use. When a Voyage ends and progression migrates to the Legacy Account layer, items the player wants to preserve are held here.

What it does: Provides organized, read-accessible storage for legacy items with Voyage of origin metadata, visual archiving, and display capability in the Port Hideout
What it doesn't do: Allow legacy items to be re-imported into active Voyage progression with their original stats (all legacy items in the Voyage Archive are display items, not active-use power items)
Price: 100 Points ($1.00) — slightly higher than a standard tab given the specific display and metadata functionality

Crew Quarters Upgrade

Crew management is one of Salt & Steel's defining systems — the procedurally generated crew members with individual names, skills, and personalities. The base ship has a Crew Quarters capacity that limits how large a crew can be.

What Crew Quarters Upgrade Is

The Crew Quarters Upgrade expands the number of crew members the captain can roster simultaneously on their ship.

Important design boundary: The Crew Quarters Upgrade does not improve crew quality. It does not provide higher-tier crew members. It does not improve any crew member's statistics, advantage profile, or skill ratings. It simply allows more crew members to be active at once.

This is a meaningful clarification: crew quality is a gameplay progression variable. Crew roster size is an organizational preference. A captain with the base crew quarters can recruit the same quality crew as a captain with upgraded quarters — they simply cannot maintain as large a roster simultaneously.

Base Crew Quarters

12 active crew slots (the actual sea-going crew)
4 reserve slots (crew in port rest, available to swap into active roster)
Total: 16 crew managed at once

Crew Quarters Expansion

Adds 4 reserve slots per expansion (no expansion to active crew — the active crew size is a gameplay balance variable tied to ship type and is not adjustable through purchase)
Purpose: Players who form attachments to specific crew members and want to maintain a larger personal roster across Voyages
Price: 100–150 Points per expansion ($1.00–$1.50)
Cap: 4 expansions (adds up to 16 additional reserve slots, for 20 total reserve slots)

What the Cap Protects

The cap on reserve slots prevents the Crew Quarters from becoming a meaningful power purchase. Beyond a certain point, additional crew slots provide diminishing practical value — the captain cannot realistically maintain meaningful relationships with 36 crew members, and the marginal advantage of a larger reserve pool is negligible. The cap is set where practical value is essentially cosmetic (the ability to keep more named crew in the roster for sentimental reasons, not for gameplay efficiency).

Learning From PoE: Where the Line Is

PoE's stash tab system evolved from convenience to quasi-essential over the game's lifetime. The process was gradual and partly unintentional — each new league mechanic added item types that stressed the existing tab system, making tabs that were once conveniences feel increasingly necessary.

Salt & Steel learns three specific lessons:

Lesson 1: Set the Base High Enough at Launch

PoE launched with 4 free tabs, which was adequate in 2013 and became increasingly inadequate as the game's item variety expanded. Salt & Steel launches with a base Cargo Hold calibrated for the complexity of the game at launch and with deliberate headroom for future content expansion.

Implementation: Before each new Voyage that introduces significant new item types, the design team evaluates whether the base Cargo Hold remains adequate for a player engaging with that content at a casual-to-moderate level. If the base becomes inadequate, the base allotment is increased for all accounts — not used as leverage for storage purchases.

Lesson 2: Never Gate Trading

PoE's requirement that Premium tabs be purchased to list items publicly is the system's most legitimate criticism. It creates an unambiguous functional gate: pay to participate in the economy's sell side.

Salt & Steel eliminates this by design from day one. All tabs support trade listing. The trading post is accessible to all players at all investment levels. Economic participation is never gated by payment.

Lesson 3: Watch for Drift

The most dangerous pattern in storage monetization is gradual drift — each individual decision seems reasonable, but the cumulative effect is a system that has crossed from convenience to necessity without any single decision feeling like the transgression.

Mitigation: an annual review of the Cargo Hold system by the design team, specifically asking: "Can a free-to-play player who has never purchased a Hold meaningfully engage with all current game content?" If the answer is no, the base must be expanded. This review is formally part of the pre-Voyage planning cycle.

Periodic Storage Sales

Storage purchases are included in periodic sale events — typically a 30% discount applied to all Cargo Hold and Port Stash expansions.

Sale design principles:

Sales run for 2 weeks, not 48-hour flash sales
Sales are not "surprise" events; the sale schedule is announced 1 week in advance
Sale frequency is approximately every 8–10 weeks — regular enough to be planned around, infrequent enough to feel like genuine value events
New accounts receive a one-time "First Hold" bundle at significant discount during their first 30 days — a conversion-oriented offer that lowers the initial investment threshold

The sale cycle creates a commercial dynamic PoE has used effectively: players who are considering purchases often wait for a sale window, which creates predictable purchase-event moments. This is commercially sophisticated without being manipulative — the discount is real, the windows are transparent, and players who prefer to purchase outside of sales lose nothing except the discount.

The Port Hideout and the Storage-Cosmetic Boundary

The Port Hideout exists at the intersection of convenience and cosmetics. Decorative items in the Port are cosmetics — they affect appearance, not function. The Port Stash within the Port is functional storage.

This boundary must be maintained clearly in the shop interface:

Port decoration items are in the Cosmetic section of the shop
Port Stash expansions are in the Convenience section
The two are not bundled (except in Voyage supporter packs, where the bundle contents are fully disclosed)

The shop interface labels every item's category explicitly, ensuring players understand what they are purchasing before they spend Points.
