Fusion Crafter is a block that is craftable in the Engender Mod.
Crafting[]

In order to make a Fusion Crafter, the player needs four Iron Ingots, four Iron Bars, and one Emerald and they need to place them as seen in the picture in a Crafting Table.
Usage[]
Placing the block on the ground will cause it to release smoke particles and will occasionally make the sounds of various Minecraft mobs, meaning some mob sounds such as the ones for the Ghast or The Wither Storm can be heard from far away. Right clicking on the block will open the Fusion Crafter menu, and in the top left corner is an area for you to put your Mana Crystal, Entropy Crystal, or Infinite Well Spring and allows you to despot and store Mana and Entropy inside of the Fusion Crafter. At the top is a slot for you to place a Fusion Part inside, and if you have the Mana and Entropy, it will take some time to fuse it before giving you your desired Mob Fusion.
