Selenite

Selenite would be dropped by exploding crying obsidian with an end crystal. Selenite could have the power to free souls from soul sand. These souls could be used to attack nearby mobs, protect you from mobs by circling around you, or these souls could be destroyed to keep you from dying. Selenite could also drain evoker’s magic turning them into an evoker with villager skin. You’d have all of the evoker’s magic but this will taint the selenite making it dangerous. Tainted selenite will decay your world, the souls that were trapped inside would attack you, effect you with wither, would destroy all life in existence, and decay your world. In order to get rid of tainted selenite the player must take it to the end where it’ll become energized and unstable. The player will have to shoot it up to the sky where it will explode and shatter. If the player throws it into the void it will destroy the end corrupting it and destroying it in the process.
