User Guide

Built for players who move the market.

Welcome to the most advanced trading utility for Creatures of Sonaria. The application is divided into three main tools:

Market Listings

Search the complete item database.

Card Maker

Build single cards or 4-slot trading decks.

W/F/L

Real-time trade valuation.


#Card Maker

The Card Maker is where you create visual listings. You can now access it directly from the navigation bar to start with an empty deck.

1

Select Item

If your deck is empty, click "Select Item" to search the database. You can add up to 4 cards to create a Grid layout.

2

Configure Slot Details

For Stored Slots, you can now enter custom ages (e.g., "10%", "67%") or pick from standard stages (Elder, Adult) in the Growth / Age field.

3

Manage Your Deck

Use the top deck strip to navigate between cards.
Add (+): Add another card (max 4).
Delete: Remove the active card.
Clear All: Reset the entire workspace.


#W/F/L Calculator

The calculator helps you determine if a trade is a Win (W), Fair (F), or Loss (L).

Manual Valuation

Since item data is sourced from the Wiki which does not track real-time market prices, you must enter the value of each item manually.

Add items to "You Give" and "You Get". The system calculates the net difference and provides a verdict based on a ±1k Mush threshold.


#Saving & Sharing

Image Export

Clicking "Copy Image" generates a high-resolution PNG of your card or grid. It is automatically saved to the History page.

Live Links

Use the "Share Link" button to generate a URL. Sending this link allows others to view your card in a "Presentation Mode".


#Frequently Asked Questions

Why can't I trade a specific item?

Some items are marked as untradable in the game data. The app marks these as "Locked" or "Untradable" automatically.

Where is my data saved?

Your history is saved locally in your browser's LocalStorage. You can view and manage it on the dedicated History page.
