About the adventure
Dungeon of the Mad Mage: Halaster's Game Dive deep into the twisted and whimsical depths of Undermountain, where madness and magic intertwine under the watchful eye of Halaster Blackcloak. In this dark yet strangely whimsical campaign, players will face the relentless horrors of the Mad Mage's dungeon, where every corner holds new dangers, puzzles, and surprises. Designed for seasoned adventurers starting at 5th level and progressing all the way to the 17th-20th range, this campaign balances roleplay (30%), combat (40%), and exploration (30%). Whether surviving gruesome traps or unraveling the bizarre mysteries woven into Halaster's Game, players will need every ounce of their wit, skill, and teamwork to overcome the odds and emerge victorious. With the added twist of Halaster's Game, expect challenges unlike any other. Players will not only face monstrous creatures and cunning enemies but will also be drawn into the Mad Mage's chaotic show, where they must adapt to ever-changing rules—or suffer the consequences. Will you survive the horrors of Undermountain, or will Halaster's madness consume you whole?

About me
Hi! I’m Michael — a 30+ year Dungeon Master who loves cinematic storytelling, emotional character arcs, detailed ambiance, and just the right amount of chaos. I bring custom lore, deep worldbuilding, atmospheric music, and player-focused storytelling to every session. My goal is simple: create a space where players feel excited, supported, and completely immersed. Come for the story, stay for the chaos.

Creating your character
Starting Level: 5 Ability Scores: Point buy OR roll twice using the Avrae bot in Discord and choose the better set—or stick with point buy. Allowed Sources: Any official D&D sourcebook I own. Unearthed Arcana & homebrew require pre-approval. Backstory & Party Ties: Players can decide if they start as allies or strangers thrown together by fate.
What to expect

Safety
How Michael creates a safe table
All safety tools and expectations will be discussed in Session 0, but here are the key guidelines: Safety Tools: Hard Line: No real-world religion or politics—this is non-negotiable. Veil: Physical romance is fade to black—no exceptions. Check-Ins: Mid-game breaks will be used to ensure comfort and fun. Gameplay Style: Rule of Cool – Creativity is encouraged, but RAW (Rules As Written) applies when necessary. Balanced Difficulty – The dungeon is challenging but fair, with real consequences for poor planning. Teamwork Encouraged – The deeper you go, the more you'll need to rely on each other.
