This mod adds 2 new magic items. One of them is crafted using a Nether Star and a Cobblestone. The other is crafted using the first one and a Chorus Flower. They are called the Withering Tablet and the Draconic Claw respectively. There will be a texture update to them eventually. You can cast the projectile by left clicking with the item in your hand. The Withering Tablet launches a Wither Skull, and the Draconic Claw launches a Dragon Fireball.
That's all there is to this mod, and I hope you enjoy!
