Dire Diary
Wondrous item, rare (requires attunement)
This diary contains 50 yellowed pages. When you attune to it, you find that the pages contain your own handwriting about events yet to come. No other creature can thereafter attune to the diary. You can use the journal to cast Dire Warning from it, filling one page of the diary with a message from the future of up to 50 words. The message may consist of a sketch or diagram, instead of writing, and is usually vague or cryptic in order to avoid paradoxes. The diary can’t cast this spell again for 7 days.
