Tasha's Cauldron of Everything. So I'll make some comments based on what little I know:
- The cover of Tasha and variant cover especially are gorgeous. I don't know the artists, but it's the first time I'm uncertain which I want to buy. I'll probably lean toward the evil Tasha (Iggwilv as we call her) because it subtly shows Graz'zt and his six fingered hand and possibly a hint of Vecna in the corner as well. The contrast of the off-white margins with her distinctive dark green apparel and dark hair along with Graz'zt's ebony form is eye-catching!
- The use of Tasha as a licensing character for a D&D book is remarkable. We've had the privilege to see Iggwilv on the covers of magazines and as interior art throughout the editions. Never before have we seen Tasha (or Natasha the Dark as she was known when adopted by Baba Yaga) depicted in this early form before she got heavily invested in demonology. There is extra art I assume from this book showing Tasha sitting outside the Hut. Love it.
- The book Tasha holds on the primary cover in Greyhawk lore could potentially be the Tome of Zyx, a book discovered by the Company of Seven back when she hung out with the likes of Zagig Yragerne who with Tasha's aid would entrap the demonlord Fraz-Urb'luu. Tasha would go on to steal this book, run off to the Yatil Mountains, become Iggwilv and add on to this book renaming it the Demonomicon of Iggwilv and go on to trap Graz'zt. I will give the writers of TCoE all my money if they manage to include all of this esoterica in their book.
- Again I'm positive about having an obscure character like "Tasha" headline this even if 99% of gamers will only know her by the Hideous Laughter spell. It's just another feather in the cap of Greyhawk as far as I'm concerned. Ed Greenwood used to write dozens of mage and spell articles for Dragon Magazine. I don't see them naming a book after the Simbul.
- As to the contents, I won't list them here. Go read the press releases and news articles online. It's a slew of new variant rules which I'm positive will be a turning point for fans of 5E D&D. I predict 6E will be informed by this book in the future. Mind you I don't believe a new edition is on the way, I'm just hoping this is a marker along the way. I'm still pleased with the pace of WotC releasing new books and stories.
- I'm very intrigued to see their magic tattoo rules. I only ever seen magic tattoos in play for Eberron (dragonmarks), but I haven't kept up with that setting in 5E, so it'll be cool to see what core D&D offers.
- I'm anxious to read the sidebar comments in Tasha. They have been a treat in previous books, so I'm positive this one will carry on that tradition.
- I'm positive I will buy this. I love anything Iggwilv related. She used to be one of my faves from my old Greyhawk webcomic.
That's all for now. Once I have Tasha CoE in my hands, we will see how it measures up!
