Mordenkainen’s Tome of Foes is the third official bestiary released for Dungeons & Dragons Fifth Edition, following the original Monster Manual (2014) and Volo’s Guide to Monsters (2016). At this point we’ve cataloged all of the creatures we’d find in a typical fantasy setting. The Tome of Foes provides much more exotic fare. If you love your cosmic horror and demons, Mordenkainen is here for you.
In the interest of reviewing a bestiary for Roll20, I’ll be focusing this review on the free Adventurer’s League tie-in adventure, “Rrakkma.”
Note that “Rrakkma” is only available to Roll20 Pro subscribers.
