Some Venomite Ore in a Wall

Venomite is the iron of The Nether. It's collected by mining and smelting venomite ore and can be crafted into swords, armor, tools, buckets, and a block. The venomite is based around poison, so a Venomite Bucket can hold poison, A Venomite Sword gives poison damage to whatever you hit, and Venomite Armour gives poison immunity. It is generally quite common. When venomite tools are cursed in the execration table, then they all (shovels, pickaxes, axes) become able to inflict poison damage, and the poison inflicted by the venomite sword when cursed will last twice as long.
