Fusion Katakuri are special buildings and traps that can turn the tide of a challenging boss fight. Unlike Dragon Katakuri, Fusion Katakuri is designed to be used on the fly during combat and is not intended to be used as long-term structures. Unfortunately, learning how to build Fusion Katakuri isn’t guaranteed unless you know the specific details needed to understand each one. This guide will break down every Fusion Katakuri in Wild Hearts and how to get them.

Where and how to get Fusion Katakuri in Wild Hearts
Unlike all other buildings and traps in Wild Hearts, Fusion Katakuri can’t be learned via the Katakuri Skill tree. The only method of learning new Fusion Katakuri recipes is an in-game mechanic called “A Flash of Inspiration.” Each Fusion Katakuri belongs to a specific boss in the game, and you must have the right basic Katakuri equipped to trigger A Flash of Inspiration. These are all the monsters you have to fight and builds you need to have equipped to learn every Fusion Katakuri in the game.
