Waterdeep: Adventures in the Forgotten Realms

T
Tome64

The City of Splendors brought to life! Designed for narrative-rich experiences in the Forgotten Realms setting of Faerun's Sword Coast. While the main focus of the world is Waterdeep, locations throughout the Sword Coast and outer planes are available as well.


Author's Note: Welcome to Waterdeep: The City of Splendors Step into one of the most iconic and richly storied cities in the Forgotten Realms—now expanded and reimagined for deeper exploration and immersive play. Waterdeep: The City of Splendors is your gateway to the Sword Coast, the Moonsea Region, and even the distant reaches of the Outer Planes. While Waterdeep remains the heart of the experience, its surrounding territories are available for those bold enough to venture beyond the city walls. This adaptation builds upon official Forgotten Realms lore, but introduces both minor and major changes to support a more engaging and open-ended campaign. For example, the characters from Baldur’s Gate 3 are playable, but have been recontextualized to exist in Waterdeep rather than Baldur’s Gate. Content is designed for compatibility with Waterdeep: Dragon Heist, Dungeon of the Mad Mage, and a host of original plot hooks waiting to be uncovered across the city’s alleys, taverns, towers, and catacombs. You’re free to explore at your own pace, shape the world as you see fit, or lose yourself in the layered politics, mysteries, and magic of the city. This is not a replacement for a traditional tabletop game—it’s a love letter to it. Dedicated to anyone who struggles to find a group and is itching to play. If you enjoy what’s inside, consider supporting the official Dungeons & Dragons books. They remain an invaluable resource for players and storytellers alike—and they make excellent collectibles.

Actions

Bite

Melee Weapon Attack: +19 to hit, reach 10 ft., one target. Hit: 36 (4d12 + 10) piercing damage. If the target is a creature, it is grappled (escape DC 20). Until this grapple ends, the target is restrained, and the tarrasque can't bite another target.

Claw

Melee Weapon Attack: +19 to hit, reach 15 ft., one target. Hit: 28 (4d8 + 10) slashing damage.

Frightful Presence

Each creature of the tarrasque's choice within 120 feet of it and aware of it must succeed on a DC 17 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if the tarrasque is within line of sight, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the tarrasque's Frightful Presence for the next 24 hours.

Horns

Melee Weapon Attack: +19 to hit, reach 10 ft., one target. Hit: 32 (4d10 + 10) piercing damage.

Multiattack

The tarrasque can use its Frightful Presence. It then makes five attacks: one with its bite, two with its claws, one with its horns, and one with its tail. It can use its Swallow instead of its bite.

Swallow

The tarrasque makes one bite attack against a Large or smaller creature it is grappling. If the attack hits, the target takes the bite's damage, the target is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the tarrasque, and it takes 56 (16d6) acid damage at the start of each of the tarrasque's turns. If the tarrasque takes 60 damage or more on a single turn from a creature inside it, the tarrasque must succeed on a DC 20 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the tarrasque. If the tarrasque dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 30 feet of movement, exiting prone.

Tail

Melee Weapon Attack: +19 to hit, reach 20 ft., one target. Hit: 24 (4d6 + 10) bludgeoning damage. If the target is a creature, it must succeed on a DC 20 Strength saving throw or be knocked prone.
