Stardust

Stardust is an item that comes in two types and can be found in the overworld (in meteors)  or on end ships. There are two types: Virtuous and Vindicative. One can be changed into the other by dealing damage with Virtuous stardust in your hand, or using Vindicative stardust on a crop (this will not deplete the amount of it you have and it does nothing to the crop). Putting either type of stardust in the middle of a crafting table with iron ingots around it will make a stardust capsule which can be thrown(and provides Regeneration III, Absorption III and Strength III or Weakness III, Slowness III and Poison III, depending on the type). Filling a crafting table with stardust wholly can make a block of stardust, allowing it to harden and be mined after, forming stardust crystal.
