D&D 5th: Tasha's Cauldron of Everything
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.
Baked into this book are rules options for all the character classes in the Player's Handbook, including new subclasses. Thrown in for good measure is the artificer class, a master of magical invention. And this witch's brew wouldn't be complete without its new artifacts, spellbook options, spells for both player characters and monsters, magical tattoos, group patrons, and other tasty goodies.
Tasha has never been shy about sharing her keen insights, and this book is sprinkled with the archmage's musings on everything from her wizardly rivs to the nature of the multiverse. Herein, she offers a taste of the great power that awaits adventurers everywhere!
