The Poisonous Potato was never useful in vanilla Minecraft by any stretch of the imagination (unless a player economy is begging for them or something). No longer will this item fall into obscurity or your nearest trash compactor.

Prepare to create massive Potato Farms just to grab this 'rare' object [Or, you know, steal them from a village or something].

Lite Version's Update: The Poisoned Sword has been added. In order to make it. Right click the air with an iron sword in the main hand and a poisonous potato in the shield hand to coat it in poison. No longer can the blade be enchanted nor can it make sweeping attacks. It's durability is halved as well. However, the damage is the same and inflicts addition poison damage upon the enemy for a period of time.

Check the File section for Lite, Hardcore, or Normal Versions

Recipes:

Wither Skulls: Fill the crafting table with Poisonous Potatos to create a single skull. This will break any economy related to Wither Skulls.

Totem of Dying: Mix a 'cross' of Gold Blocks with Poisonous Potatos on the corners to create the totem. This will also break Undying Economies.

Dragon Breath: Hate having to respawn the Ender Dragon for these things? Just pop a Popped Chorus Fruit inbetween 8 Poisonous Potatos to get one.

The Return Harvest Update:

-Poisonous potatos can now be converted into iron and gold ingots using campfires and grindstones, respectively.

-Pig spawners can now be crafted (Since mcreator does not supply specific or random spawners). This requires the crafting of a Mob Spawner Gem

Hopefully, this mod can create a Poisonous Potato Economy or help with players that aren't allowed to go to the Nether or the End, and will not search for Mansions and die just for an item that can prevent 1 death.

Feel free to leave a suggestion for a future update
