DotMM Companion 23: Mad Wizard's Lair


The day has come at last for the adventurers to square off against Halaster Blackcloak in his private sanctum. However, the ending provided in Dungeon of the Mad Mage is lackluster at best. The final chapter of the DotMM Companion completely overhauls the level by adding the following features:

  • In the Kingdom of Madness: a complete overhaul of Halaster's tactics, prepared spells, magic items, and more, made in an effort to satisfy the expectations of a master wizard who knows the enemy is at his gates.
  • Penultimate Encounters, which function to soften up the adventurers in an unforgettable fight. The Dungeon Master has their choice of hurling one of these at the party:
    • The Elite Four: the adventurers must battle Halaster's four surviving apprentices in sequence!
    • The Prismatic Gauntlet: the adventurers must grapple with a prismatic wall while under assault by Halaster's minions!
    • Tarrasquic Park: the adventurers are teleported to a zoo-of-a-demiplane in which a tarrasque hungers for a hunt!
    • Welcome to the Thunderdome: the most basic encounter, it pits the empyrean Nalkara (heavy weight champion of Enter the Arena) against the party in a hemispherical wall of force while legion fans watch.
  • Ultimate Showdownencounters, of which the DM should choose three!
    • The Big Halowski: the adventurers are the unwitting pins in Halaster's lethal game of bowling!
    • Checkmate: Halaster has kidnapped friends and foes across Waterdeep and Undermountain, pitting them in this game of living chess. As the adventurers find, both enemies and allies have been placed on their team and Halaster's, forcing them to choose which innocents live or die.
    • Clash of the Titans: a complete overhaul of Halaster's fight with the adventurers in his throneroom. This counts as three encounters.
    • Donkey Kong Redux: the adventurers must scale several ladders while under assault by barrels hurled by a giant ape!
    • Monty's Hall: the adventurers have three doors to choose from, and only one leads out of the demiplane Halaster has condemned them to! Better pick quick, otherwise the delayed blast fireball erupts!
    • Planar Hopscotching: Halaster battles the adventurers throughout the Multiverse! This counts as two or more encounters.
    • Snakes and Portals: can the adventurers catch Halaster as they race across the boardgame, beset by serpents and walls of acid?
    • Third Times the Charm: replacing all other encounters, the adventurers continuously battle Halaster each time he resurrects. In their final encounter, the Mad Mage drops the asteroid Stardock out of orbit and hurls it towards Toril! Only by the grace of Jhesiyra Kestellharp do the adventurers arrive in time to put an end to Halaster's fetal rampage!

As usual, this chapter of the DotMM Companion also includes:

  • DM Notes. Notes including but not limited to spicing up the dungeon crawl with valuable roleplay with select NPCs.
  • Areas of Note. Notes, room descriptions, scenes, and scripts for the various areas of the dungeon.
  • Magic Item Descriptions. Save yourself the time of digging through the Dungeon Master's Guide to determine how the few magic items on this floor work. The appendix also lists the area the item is found.
  • Monster Stats. Statistics are provided for all unique NPCs used on this level.

    Rules Edition(s)
    Original electronic
    Scanned image
    These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

    For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

    For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
    Original electronic format
    These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
