Fate of the Fogweaver.

Sapphire Strait → Shipwrecked → Sunken Condition → Boss Encounter → Epilogue

The Sapphire Strait introduces the setting and lets players describe their characters in a moment of victory. In the first playtest, this was a full combat encounter. When runtime exceeded limits, I realized this scene's purpose was to introduce the players heroically - switching it to narrative was the perfect solution.

Shipwrecked introduces the central mystery and Bellio, an NPC my son created. Bellio provides both comic relief and a way to keep players on track. His ability to become invisible highlights a magical tattoo that lets characters see invisible creatures - important for the adventure's turning point.

Playtesting revealed the need for alternative exploration paths. I created multiple routes (including investigating a second ship) that preserved player agency while keeping them moving toward the objective.

To advance to the next section, I designed three different paths that each highlighted different player character options - one via magical tattoo, two via character abilities.

Sunken Condition shifts the tone from high fantasy swashbuckling to dark eldritch horror, a core theme of SINK!. This section establishes the risk/reward mechanic and real stakes. Die here, and you end up in the dunk tank.

The objective was to pay off the motivations, mysteries, and mechanics established earlier. The adventure's big bad is revealed through character-specific clues, setting up the final encounter.

Boss Encounter

The boss fight needed to be deadly enough to threaten the dunk tank, scalable for unknown party composition, and completed within the remaining time budget. I designed three mechanics:

The Duplicates The Fogweaver summons duplicates equal to the number of players. For each duplicate, he gets an extra attack via Legendary Actions. They share a hit point pool (75 + 25 per duplicate). For every 25 damage dealt, a duplicate is destroyed. Finally, The Fogweaver takes no direct damage until all duplicates are eliminated. This scaled the encounter perfectly regardless of party size.

The Illusion A massive illusion of Y'gathul looms over the battlefield. I started a visible 10-minute timer when initiative was rolled. Every 10 minutes, the illusion unleashes a wave of force:

• Each creature makes a Constitution save (DC = 10 + number of activated statues)

• Success: Lose a hit die

• Failure: Lose a hit die and take damage equal to the roll

• Failure by 5+: Take maximum hit die damage

This created real pressure without relying on me to track time secretly. Players could feel the clock ticking.

The Statues Six statues surround the arena, whispering offers of power. Players can accept help once per turn (turn a miss into a hit, a hit into a crit, negate an attack). Each time they or the Fogweaver do, the illusion's save DC increases, further escalating tension.

When all six statues activate, the Fogweaver's third eye opens:

• His multiattack increases from 2 to 3 attacks

• The illusion triggers on initiative count 20 in addition to every 10 minutes

This gave players a meaningful choice. Accept power now at a narrative loss and a harder fight later, or struggle early for an easier endgame. Risk and reward, mechanically enforced.
