Book of Time (5e Equipment)
From D&D Wiki
Wondrous Item, Legendary (Requires attunement by a spellcaster able to cast Chronomancer spells)
A gift from the gods of the Astral plane, the Book of Time is bestowed to only those with the greatest potential. This leather bound book is sealed with cold iron, magical wards, and many other methods to prevent anyone but the intended target to read it. The spine of the book bears the words "A Complete History."
When given a Book of Time by a god of the Astral plane, a chronomancer must automatically attune to it, losing another item if necessary. Any other spellcaster able to attune to it must follow the following steps.
The mundane locks are immune to magical effects and require a DC 30 Strength check to break. The wards on the book are written in a completely alien language and require a DC 30 Intelligence check to read. Successfully reading the wards reveals constantly changing words and patterns surrounding the words "Book of Time." The wards require a DC 30 Intelligence (Arcana) check to break, this check is made with advantage if the wards have been read within the past 30 seconds. Failing any of the above checks results in taking 3d12 psychic damage. 30 seconds after the first lock is broken, whether mundane or magical, the book repairs and resets itself, effectively nullifying all progress made to open it. A chronomancer other than the intended target cannot attune to the Book of Time until it has been opened.
Alternatively, the reader may, during a long rest, use the Book of Time to commune with the Lord and Lady of Time and Fate. In doing so, the reader may ask any questions about future events, but they will only answer with yes or no/true or false/etc. The reader can only ask 5 questions in the span of a week, any further questions will be met with silence.
The Lord and Lady will, on occasion (DM's discretion), choose to answer a question with a prophecy instead of a yes or no. These occasions usually speak of events that could cause great fluctuations in the timeline.
