Overall I would say this about Tasha's Cauldron of Everything: I like it. There is nothing that I have seen that isn't fine. I like the expanded features they have given existing classes as it offers more options and I think even managed to round out the classes better.
I like the Psionic Warrior - a cool little Jedi sort of class.
There is still much for me to review when I find the time, but you all should consider using what is appropriate from this book to round off your characters (Adding the extra class features and spells). If you have any questions, please ask. I always reserve the right to nix any of this optional stuff if it seems broken or I don't want it in the game. But you know me, I'm pretty flexible.
Let me know what you think of the book. What are your favorite things in there?
