Description from the publisher
The wizard Tasha, whose great works include the spell Tasha’s hideous laughter, has gathered bits and bobs of precious lore during her illustrious career as an adventurer. Her enemies wouldn’t want these treasured secrets scattered across the multiverse, so in defiance, she has collected and codified these tidbits for the enrichment of all.

Full of expanded content for players and Dungeon Masters alike, this book is a great addition to the Player's Handbook and the Dungeon Master’s Guide.
