Soul Reaper Enchantment

With the Soul Reaper enchantment, you gain the ability to collect the souls of defeated enemies and use them to create unique lighting elements in your constructions.
Important: this enchantment can only be discovered in mineshaft passages.
Souls

Collected souls can be placed on surfaces to create illumination. Each soul can be enhanced by adding additional souls to it - this increases the size of the glowing sphere and expands the lighting area.
Soul Torch

You can craft special soul torches from the obtained souls, which will be a great addition to your arsenal of light sources.
Soul Bowl

Using the appropriate blueprints, you can create a special bowl-bracelet for elegantly placing souls in your interior.
Soul Glass

Simply right-click on a glass block while holding a soul to place it inside the glass, creating an unusual lighting element.
Wisp Spirit

When defeating living creatures, there's a small chance for a wisp spirit to appear. If you manage to defeat this creature, you'll receive a soul as a reward.
Color Changing

While holding dyes in your inventory, hold the Shift key and right-click on a soul or soul torch to change their color to any desired shade.
