Urim

Wondrous item, legendary (requires attunement by a cleric)

This small polished stone of white marble pulses with divine energy. Roughly translated as either “revelation” or “curses,” the Urim was used in ancient times by priests as a method of divination. After the kingdoms of Israel and Judah were destroyed by Babylon, the Urim and its counterpart, the Thummim, were lost to history... until now.

The Urim in your possession is imbued with residual divination magic that grants you the following benefit:

Once per day, you can cast the augury spell from the Urim, requiring no material components.

Developments. If you reunite the Urim and Thummim, becoming attuned to both simultaneously, their powers combine to form a legendary artifact of tremendous power. While attuned to both stones, you can see beyond the veil and have the ability to peer into the immediate future. You gain the following benefits:

You cannot be surprised; surprise does not impose Disadvantage on your Initiative rolls.
You have truesight out to a range of 30 feet.
You gain a bonus to your AC and saving throws equal to your Wisdom modifier.
