This is a really excellent and fun subclass that has a strong theme and beautiful layout. I love the rules for mathematical tools, and I know that my groups will love seeing PCs or NPCs from the College of Calculation! My only quibble is that there are a handful of typos and places where the PHB is referenced instead of reproducing the text, which would be more useable. I'm happy to provide notes on those if desired!

I had high expectations for a product from veteran designer James and witch-artist extraordinaire Kayla, but Hagmalgams exceeded my wildest dreams! These hag hybrids are charming as well as unsettling, and are perfect for surprising unsuspecting players with a new friend...or foe.

This is a brilliant subclass and set of feats, with gorgeous art by the author and a strong, well-executed theme. It'd make an excellent addition to any table that enjoys forging strong bonds between characters, and could also be used to inspire for some fantastic NPCs. The excellent writing and editing gives it personality and polish!

Lots of great ideas in here! It could use a proofread, and the monk feature seems overpowered, but I love the ranger and sorcerer options and will definitely offer those to players in an epic-level game!

Really nice companion to Xanathar's guide to everything. I especially love the new options for barbarians, bards, and druids, and the urban dryads. The art is absolutely gorgeous, too. I'm looking forward to the corrections in the errata, but overall this is a solid, indispensible addition to my virtual D&D shelf.

Awesome inspiration for new encounters, adventures, and plothooks—now I want to run an adventure (or three) that involves some of the ancient gem dragons. Full of clever detail and engaging prose. I particularly enjoy how each type of dragon has a unique breath weapon, which offers some great options for surprising and challenging encounters.
