Introduction to Descent Into Avernus

The story follows the fall of Elturel and the players’ quest to save it, ultimately placing them at the heart of a celestial and infernal conflict.

Why Foundry Is the Ideal Platform

Foundry Virtual Tabletop stands out due to its flexibility, dynamic lighting, macro scripting, and community module support.

Key Locations and Encounters in Avernus

Elturel’s Fall

The descent begins with the fall of the holy city of Elturel into the hellish realm of Avernus. Foundry can visually depict this catastrophic event with animated skies, falling debris, and screaming NPCs. With dynamic lighting and sound integration, DMs can make players truly feel the chaos and despair of the opening scenes.

Traveling the Wastes

Exploring Avernus is not a traditional trek. The land constantly shifts, distances change, and infernal storms tear through the sky. Foundry’s hex-based exploration maps or distance randomizers can simulate the unstable terrain. Use fog of war and conditional visibility to heighten the sense of uncertainty and danger.

Infernal War Machines

One of the standout mechanics in Descent Into Avernus is the use of infernal war machines. Foundry enables interactive vehicle mechanics, allowing players to pilot war rigs through the wastelands, track fuel (soul coins), and engage in high-speed chases. Implement macros or module support for vehicle initiative and actions to streamline the process.

Fort Knucklebone and Mad Maggie

Fort Knucklebone, the scrapyard headquarters of Mad Maggie, is a narrative hub filled with eccentric NPCs and weird machinery. Foundry lets DMs build this map with cluttered junk, strange magical effects, and moving parts. Interactive elements like buttons, levers, and doors can be placed to trigger dialog, traps, or mini-quests.

Zariel’s Domain

The climax of Descent Into Avernus brings players face-to-face with Zariel, the fallen angel who rules Avernus. With Foundry’s scene layering and atmospheric effects, the battlefield can glow with celestial light, roiling fire, or rivers of blood. This confrontation is not just a fight it’s a pivotal moment of redemption or damnation. Let the mood and visuals reflect that weight.

Combat, Dialogue, and Moral Choice

Combat in Avernus

Encounters in Avernus are brutal and chaotic. Use Foundry’s automation features to track conditions like frightened, charmed, and grappled, which are common in fiendish battles. Foundry allows for animated spell effects, health bars, and initiative trackers, speeding up gameplay without reducing immersion.

Dialog and Roleplay

With NPC journal linking, chat macros, and character portraits, Foundry enhances the roleplay experience. When players speak with devils or make deals with fiends, you can pull up infernal contracts or visual aids directly in the chat window. Decision points can be tied to handouts or rollable tables to simulate moral dilemmas and consequences.

Choices That Matter

Descent Into Avernus thrives on difficult choices. Will the party sacrifice innocents to gain power? Will they try to redeem Zariel or destroy her? Foundry’s scene tracking and conditional triggers let you reflect player choices in real time. For example, if the party redeems Zariel, the final map can change with angelic light and healing zones replacing infernal hazards.

Customization and Advanced Features

Dynamic Maps and Lighting

In Avernus, light is both rare and dangerous. Foundry’s dynamic lighting allows you to control exactly how much visibility the players have. Create pitch-black dungeons with glowing runes, or make burning landscapes that flicker with lava flows and collapsing terrain. Environmental storytelling becomes far more impactful when players can see the danger.

Sound Design and Immersion

Foundry supports ambient sound layering, enabling you to add screaming souls, infernal engines, or celestial choirs depending on the location. Use spatial sound effects to indicate proximity to hazards or NPCs. A simple drone in the background can make a wasteland scene feel unsettling and alien.

Token and Actor Management

Use actor templates for recurring devils or infernal creatures, saving time during setup. Foundry’s drag-and-drop system makes it easy to introduce surprise enemies or environmental hazards. Reusable actor sheets let you customize Zariel, Lulu, or Bel with unique stat blocks and animations for epic scenes.

Player Tips for Foundry in Avernus

  • Keep your character sheets updated with infernal contracts, soul coins, and magical boons earned throughout the journey.
  • Use journal notes to track moral decisions and consequences.
  • Familiarize yourself with vehicle mechanics if your party uses war machines frequently.
  • Discuss with your DM how far you’re willing to go morally Avernus will test your limits.

Running Descent Into Avernus in Foundry Virtual Tabletop is a transformative experience that elevates the campaign’s intensity, drama, and immersion.
