Mini-Dungeon #323: Claws in Cold Water

A DnD 5E Festival Adventure – Conquer the Totem Dive, a thrilling DnD 5E water adventure!

Looking for a vivid DnD 5E festival challenge to drop into your icy northlands or lakeside campaign? Rybalka’s beloved spring tradition, the Totem Dive, is underway. Teams plunge into the freezing shallows of Serpent Lake in a relay-style contest to recover carved animal totems scattered underwater. Friendly rivalry, community pride, and seasonal celebration set the tone. However, something far more dangerous stirs in the depths.

This year, an unwelcome kra’tah has claimed one of the deepest totems. As a result, the competition becomes a sudden struggle for survival. What begins as a festive challenge soon becomes a rescue effort and an underwater chase. Ultimately, it evolves into a monster hunt across the lake’s icy outskirts. Therefore, the heroes must adapt quickly or the festival will end in disaster.

What’s Included

• Festival-Themed Challenge Adventure
  Join the annual Totem Dive alongside local teams of warriors and fishers. Recover totems at 10, 20, and 30 feet in a structured, round-based underwater relay where perception, timing, and stamina matter.

• Cold-Water Survival Hazards
  The frigid waters of Serpent Lake threaten divers with hyperventilation and hypothermia. These environmental rules add tension and realism as characters push their limits in the icy depths.

• Underwater Monster Encounter
  A kra’tah lurks at the edge of the contest area with a totem lodged in its shell. Clever divers may retrieve it unnoticed, but any misstep unleashes a dangerous attack. Victory can earn bonus rewards, including valuable kra’tah roe.

• Expanded Adventure Sites
  If the creature escapes, the pursuit leads to a nearby island featuring a haunted cellar, a decrepit dock rich with bloody lichen, fallen trees hiding rival warriors, and a kra’tah nest within ruined longhouses.

• New Resource: Bloody Lichen
  This rare lake growth can be harvested and powdered to briefly stun and blind a kra’tah. Consequently, it gives clever parties a tactical advantage.

• Fully Illustrated Map
  Includes a complete dive zone and island map with clearly numbered locations, ideal for in-person play or VTT integration.

• New Monster
  A Mini-Dungeon first! A new monster is included with your dungeon. The deadly kra’tah as seen in A03: Champion’s Rest has resurfaced and been completely rebuilt for D&D 2024.

Level Range

Designed for 4–6 characters of levels 3–4, it offers a perfect mid-tier festival sidetrek. In addition, it serves as a short, punchy challenge between major quest arcs.
