About the adventure

Get ready for the dungeon that puts all others to shame! Undermountain is a HUGE, seemingly bottomless dungeon of monstrosities waiting to be vanquished by you and your party! Fight nearly everything in the monster manual from Goblins to Dragons, Liches and Mindflayers alike wait in ambush as you delve deeper and deeper into the dungeon and unveil its many secrets! Entire biomes are scattered within, even towns have been established inside. In the city of Waterdeep rests a tavern called the Yawning Portal, named after the gaping pit in its common room. At the bottom of the crumbling shaft is a labyrinthine dungeon shunned by all but the most daring adventurers. Known as Undermountain, this dungeon is the domain of the mad wizard Halaster Blackcloak. Long has the Mad Mage dwelt in these forlorn depths, seeding his lair with monsters, traps and mysteries. To what end? That question is a constant source of speculation and concern... Undermountain is the largest canonical dungeon in the Forgotten Realms, and now you can explore it in an entirely 3D environment thanks to the TaleSpire platform!

Additional Details

How to prepare

You will need to buy TaleSpire on Steam. You cannot play without it. Once you schedule a session I will send you an invite through discord - we will use this for voice chat so you will need a mic. Download BeyondtheSpire for Firefox or Google Chrome beforehand as well: Using this tool is very easy, just be sure to turn off dice rolling on your Beyond character sheet by clicking the gear next to the character name and the switch will be on the menu that pops up. Your character's stats, hit bonuses and damage dice will be highlighted and when you click them while Beyond the Spire is active it will send your bonuses to TaleSpire and you can roll them in game.

What I provide

Fully made dungeon on TaleSpire D&D Core Rulebooks

Gameplay details

SAFETY: This is a campaign length dungeon crawl, expect large levels of violence, NPCs in distress, descriptions of gore, etc. at the start of the game we will go over lines and veils, lines being things that have no business appearing in a game meant to be fun and engaging and veils being things that can be hinted at but not focused on, like pulling the curtains over a scene. If at any time you as the player feel uncomfortable you can send me a message during the game and will discontinue any further reference to the subject. Most of my games will contain adult language (R) and I will allow it from players as long as it is purely for fun or used for expression in character - I expect my players to be kind and courteous towards each other always. Name calling, and major PC betrayals are hard lines for my games. The rogue can pickpocket the paladin, but I draw the line at killing fellow PC's for any reason. Otherwise murder hobos are okay in my books as well.

How will character creation work
