D&D 5E - Mordenkainen Presents Monsters of the Multiverse Review.

The clockworks are in Tome of Foes, as are the Sorrowsworn (and yes, they all got renamed, again probably so they could be kept together in the book).

Interestingly, Volo's included a statblock for ordinary cows and then had some text on how to adjust it for oxen, rothé, and stench kows. I note that in MotM, oxen, deep rothé, and stench kows now have their own individual statblocks, while there are no stats for ordinary cows (or ordinary rothé). I wonder if maybe the ordinary cow will be included in the revised PHB/MM.
