The Tesseract

This perfect cube with handles on either side of it
is made of obsidian, glinting with hints of light
from within.
After attuning to it for 1 Hour, the Tesseract
grants a Single Point of Luck to any one
individual who invests their Soul with the
Spark of Possibility. This point of Luck can be
used as per the Feat: Luck. This Luck point lasts
for 8 Hours or until a Long Rest.
