Development

Introduction

Crafting requires resources and development materials (one dev. mat. is required for each attempt). The rarity and success rate depend on the resource recipe used and your flagship's class.  Your flagship is the lead ship in your fleet marked #1.

Often you will fail to produce an item from a recipe, denoted by the penguin-in-a-box screen.  In this case, the development material used will be refunded.  Development materials can be found by completing quests, expeditions, and World 2-4.

Development recipes

NOTE: These recipes are the minimum required resource costs, condensed down to the most recommended equipment for ease of navigation and use.  If you would like to see recipes for other items, please see List of development recipes by item.
