Top Reviews

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Marina (DTRPG customer)

"The art for Elemental Lairs is incredible. I also like the layout. The pdf in particular has lots of links that can be used to jump to information easily. [It has] excellent suggestions for adjustments that can be made to games to make lairs and boss fights interesting, epic, and unexpected. Even outside of boss fights, much of it can be used to make more dynamic terrain encounters. Legendary Lairs: Elemental Lairs would be an excellent addition to any Game Master's collection."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Robert (DTRPG customer)

"MageGate has useful, usable, thematic lairs. The legendary and lair actions help flesh out how and why to use them, adding flavor to whatever level your encounters are set for."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Neill W. (Amazon UK customer)

"...An absolute masterclass in mechanical depth for 5e boss encounters. The "crunch" is exactly what I look for—each lair provides a wealth of modular tools, from dynamic terrain and hazardous environmental effects to perfectly tuned Lair and Recharge Actions that make every encounter feel like a tactical puzzle rather than just a bag of hit points. What really sets this apart for my style is that these aren't just generic combat arenas; the book actively encourages GMs to weave the boss’s history and motivations directly into the environment, allowing for the kind of narrative cohesion that keeps players fully invested. If you want to elevate your climactic boss fights from simple skirmishes to epic, memorable showdowns, this is an essential addition to your DM toolkit."



⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Amazon customer

“If you’re looking for inspiration for your boss or their lair, this is, without a doubt, the best work out there.”

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — MageGate customer

"This book has everything a GM needs to run years of cinematically themed encounters and lairs. Best of all, there's zero filler, no lore dumps, just straight up, serious crunch."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Peter B. (Amazon Netherlands customer)

"This book allows you to go beyond the standard encounters a DnD session usually has and sets you up to create a custom crafted monster lair or themed dungeon where you won't just be fighting the monsters and traps, but the terrain itself. It is a book that helps fill a dungeon/lair with atmosphere that does not just look the part, but adds to the experience. A worthy successor for Magegate's previously released [Extreme Encounters: Weather & Terrain] series. I recommend both as a good little bit of extra seasoning to spice up encounters."

⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Paul M. (MageGate customer)

"Good plug-and-play book for intermediate to experienced GMs. Lots to chew on. Would have liked more minions and magic items, but the ones it does have are cool and give me a lot of ideas to make my own."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Kurt P. (MageGate customer)

"What I like most about this book is how easy it is to drop a template into an encounter. I don't have to change anything I wrote, I just add the template on top to instantly make the encounter better. And it's not just for more fun for me (mwahaha!) but more memorable for my players. Since I started using this book, I've never seen them so engaged."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Jim W. (MageGate customer)

"As a GM, I put a lot of work into my session prep. But since getting Legendary Lairs, I've been able to cut prep time in half. It really is that easy. 5 stars!"

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Alan D. (MageGate customer)

"This is the kind of book GMs wait their whole life for. It makes me look like a genius. Seriously! There's no way I would have thought of even half the stuff MageGate does."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Sara G. (MageGate customer)

"Impressive! Covers everything you'd expect and more. Beyond the plentiful lair actions, the mix of magical and nonmagical terrain and traps ensures this book will see heavy use for years to come."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR ELEMENTAL LAIRS — Oliver E. (MageGate customer)

"I learned more from this book than just about any other book on how to GM. The best part is, it's not just giving advice, it's handing you a 'better GM blueprint' with tons of simple to advanced templates. You can mix-and-match, tweak, and use them over and over. This book is a treasure chest of ideas no GM should live without."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR UNEARTHLY LAIRS — MageGate customer

"As good as Legendary Lairs: Elemental Lairs, the first volume? I’m even more inspired. Spooky and spectacular! So many creepy evocative names, effects, and creature ideas for a whole host of lair types. There’s so much flavor and crunch you won’t be able to resist adding new story wrinkles to your campaign."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR UNEARTHLY LAIRS — Robert (DTRPG customer)

“The lair and legendary actions fit the themes so well, and they inspire me to rethink my approaches to locations and boss fights. Together, they add cool abilities, hazards, and threats that bring variety and flavor to your game.”

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR UNEARTHLY LAIRS — Terry (DTRPG customer)

"The author says ‘You’re not just getting ideas—you’re getting a framework you can rely on every session’ This is exactly right.

So is it repeatable in the sense of repetitive? No. There are so many ideas and such great original flavor in each realm, lairs will never feel like more-of-the-same.

A slow walkthrough building a sample simple lair might enhance the accessibility of the Legendary Lairs series as it might be a lot for a beginner DM."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR UNEARTHLY LAIRS — Steve R. (MageGate customer)

"This makes my favorite monster and villain locations not only smarter, but a hundred times more fun. Perfect for cursed, haunted, and toxic locations."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR UNEARTHLY LAIRS — Sean B. (MageGate customeR)

"Get this book if you want to terrify your players! It has so much crazy horror stuff I can't believe it. This is the definitive book for making the game scary again."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR UNEARTHLY LAIRS — Rob O. (MageGate customer)

"If you love danger and horror—the kind that is sadly missing from most 5e books—Unearthly Lairs delivers. While it's for 5e, it feels very OSR-adjacent. Grognards will love it, but it's not just for them. It's for anyone who wants more out of their 5e game. More thrills, more chills, more everything dark and dangerous."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR UNEARTHLY LAIRS — Ken K. (MageGate customer)

"I've always struggled to make store-bought adventures feel more like my own, and Legendary Lairs lets me do that. Without stressing, without hours of prep to "fix" them. As soon as I read it, I felt like I leveled up as a GM. That's how good it is. Belongs on your shelf next to The Lazy Dungeon Master and The Monsters Know What They're Doing."

⭐⭐⭐⭐ VERIFIED REVIEW FOR UNEARTHLY LAIRS — Robin U. (MageGate customer)

"Interesting, meaty book for GMs seeking to bring darker locations like haunted ruins and swamps to life. Older or more experienced GMs will appreciate the many options, but it might be overwhelming for younger/newer GMs. Regardless, it should give them plenty of ideas and inspiration."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR UNEARTHLY LAIRS — Dirk F. (MageGate customer)

"This is perfect for my dark fantasy-grimdark-gothic horror game. Whether you run Ravenloft or your own sinister setting, this book will give you the tools you need."

⭐⭐⭐⭐⭐ VERIFIED REVIEW FOR UNEARTHLY LAIRS — Nick C. (MageGate customer)

"Great book with great art and advice. Easy to read, easy to run at the table. No more boring bad guys or dungeons!"
