The Corrupted Ender Sword is an advanced-game craftable sword for fighting End-native mobs. The sword is made from two Corrupted Ender Diamonds and an Entwined Handle.
This sword deals special damage to mobs native to the End dimension like endermen and dragons; in particular, endermen are so debilitated as to no longer be able to teleport away from the player when attacked. Other kinds of mobs are infected with the corrupting Ender Fever in addition to receiving severe hit damage. Ender fever makes a mob teleport randomly at an accelerating pace until it literally explodes. The sword has a much shortened attack cooldown and is highly durable at 2x that of an Enhanced Diamond Sword or ~5x that of a diamond sword.
Eye of Giants (Dragons)
To create the corrupted diamonds, you need an Eye of Giants (Dragons) which is a new loot item dropped by ender dragons killed by actual players. The drop rate is 75% with a bonus 2% per looting enchant level.
Corrupted Ender Diamond
Once you have the eye of giants, you need to further corrupt it with a Dark Tome you've found in a plundered Beanstalk's loot. Combine the eye with the tome on a standard anvil or equivalent as shown below; this process requires a boatload of experience points. The Dark Tome's level (I-III) indicates how many corrupted diamonds the tainted eye will produce. Note that you can repeat this process to "refill" the eye with new corruption after you've used it to make a set of diamonds. Once tainted by a dark tome, an eye of giants can be restored to its original form only by applying an Uncrossing enchantment.
Now using a regular crafting grid, you can convert Enhanced Diamonds into corrupted ender diamonds. This is a shapeless recipe.
