5 INTRODUCTION Legendary actions are one of the coolest, most memorable aspects of fifth edition for me. As a DM, they allow you to make dynamic choices throughout a combat round, not just relying on a single action to make a huge impact. This element of unpredictability keeps the more tacticsminded players guessing as well, which is likely a big reason they come to the table. Fifth edition’s legendary actions address one of the biggest problems in previous editions: ‘big bads’ often needed a lot of minions to survive more than a couple of rounds against cunning players. This never felt quite right for every ‘boss’ encounter; sometimes a creature is solitary and should be fearsome on their own. We wanted to take this concept and apply it to a wider range of creatures. It certainly makes sense that an ancient dragon could be ‘legendary,’ but why not a mage who has errected a black tower in the hills, terrorizing villages and travelers alike? You can take a simple mage and turn them into Ugon the Doom of Beregost, an NPC the characters can form a story around. Adding legendary actions to low-CR creatures makes them truly memorable and it surprises veteran players who have memorized the existing ones. HOW TO USE THIS BOOK We wanted this book to be as easy to use at the table as possible. You get exactly what is on the tin: legendary action options for CR 4–6 monsters and NPCs from the Monster Manual, Volo’s Guide to Monsters, Mordenkainen’s Tome of Foes as well as the setting guides Guildmasters’ Guide to Ravnica and Eberron: Rising from the Last War. You can either look up a creature ahead of time and create a ‘boss’ version of them, or even add to a planned encounter on the fly. The latter option is particularly great if the player characters have blown through what you thought were some really challenging encounters and you still want to test their mettle. DESIGN AND CHALLENGE RATINGS As we worked through this project, we wanted to hold ourselves to a few design constraints, which I hope we have successfully delivered: Ù When possible, creatures should have a mix of low- and high-impact legendary actions. These range from simply moving to a whole new mechanic for the creature. Ù Deliver on the theme of the existing creature; a legendary berbalang should not become a huge hulking brute. Adding legendary actions to a lower-CR creature certainly makes for a more difficult encounter. We have not recommended a specific CR increase, but if you use traditional XP for character advancement, you may want to consider offering an additional 50% or so XP for defeating a legendary creature. You may also decide to introduce one of these legendary creatures to a higher-level party than their CR would typically merit. If you do this, you may want to consider raising the creatures AC, hit points, attack modifier, or spell save DC. There’s a great ‘cheat sheet’ for that on the Blog of Holding, which you can find here: Blog of Holding We hope you enjoy what’s inside, and thank you for your support! Christopher and Christian
