Crafting the Ender, Thunder, and Wind Sword Variants
Ender Sword Family
The Ender Sword is the base of the Ender line. From it you can craft the Tri-Ender Sword, the Ender Fire Sword, the Ender Portal Sword, the Ender Thunder Sword, and the Ender Wind Sword. Each variant adds a different element on top of the Ender base.
To make these, hold the Ender Sword and combine it with the matching elemental sword or Essence. For example, the Ender Fire Sword pairs the Ender Sword with Fire, the Ender Thunder Sword pairs it with Thunder, and the Ender Wind Sword pairs it with Wind. The Ender Portal Sword and Tri-Ender Sword are the top of this branch and need the most materials.
Thunder and Wind Lines
The Thunder line runs Thunder Sword into Thunder Shock Sword and Thunderstorm Sword, and then into the Meteoric Thunderstorm Sword. The Wind line runs Wind Sword into Wind Blast Sword, Wind Boom Sword, and Wind Impulse Sword.
Keep the intermediate swords. The Thunder Shock Sword and Thunderstorm Sword are both ingredients on the path to the Meteoric Thunderstorm Sword, and the Wind Blast Sword and Wind Boom Sword feed the Wind Impulse Sword.
If you are short on Thunder Essence or Wind Essence, run the lower swords through the Transmutation Furnace with the Essence you do have. The furnace handles the combines that the crafting table rejects, so check there whenever a recipe will not appear.
