How to Use the Crafting Calculator

1

Search for Items

Use the search bar in the left panel to find craftable items. The search supports partial matches and filters items as you type.
// Search filters items across all craftable categories
// Located at: src/pages/Crafter.tsx:84-90
2

Add Items to Your List

Click on any item from the left panel to add it to your crafting queue. Items appear as cards in the main area with their recipe details.
If you add an item that’s already in your list, it will increment the count instead of creating a duplicate entry.
3

Adjust Quantities

Each selected item shows a quantity counter. Change the count to calculate materials for multiple copies of the same item.The calculator automatically recalculates all material requirements when you adjust quantities.
4

View Total Materials

Scroll to the bottom to see the “Total Materials” section, which aggregates all base resources needed across your entire crafting list.This consolidated view helps you gather resources efficiently before starting your crafting session.

​
Recipe Breakdown System

The calculator shows a two-level ingredient tree for each item:
  1. Primary Ingredients: Direct materials needed to craft the item
  2. Secondary Ingredients: Materials needed to craft the primary ingredients
The system stops at two levels to keep the interface manageable. For deeper recipe chains, add the intermediate items separately.

​
Sharing Crafting Lists

You can share your crafting setup with clan members:

​
Via URL Parameter

Add items to your list, then share the URL. The recipe parameter encodes your entire crafting queue. Example URL format: 
https://stiletto.com/crafter?recipe=ENCODED_RECIPE_ID
Share a link that pre-populates the search with a specific item: 
https://stiletto.com/crafter?craft=ITEM_NAME

​
Reporting Issues

If you find incorrect recipes or missing items, use the Report Bug button (exclamation icon) next to the search bar to submit corrections.

​
Search Tips

  • Multi-word Search: The search supports multiple terms. Type "iron tool" to find all iron tools
  • Case Insensitive: Searches work regardless of capitalization
  • Live Filtering: Results update as you type, showing only matching items
