The Froghemoth Swarm: A Swamp on the Brink
Last week I dropped that the Froghemoth Elder was being released. But what happens if you have more minis than just the one elder? If one Froghemoth Elder is terrifying, a swamp filled with these monstrosities and their offspring could spell doom for an entire region. Imagine a festering, alien ecosystem that churns out these enormous amphibians like a natural disaster given life. This scenario not only amps up the stakes but also offers your players a layered challenge filled with combat, strategy, and environmental puzzles.
Here’s how to bring the Froghemoth Swarm to life in your campaign.
The Swamp of Spawn: The Elder’s Breeding Grounds
In a forgotten stretch of the world lies the Swamp of Spawn, a dense, humid mire that feels alive with danger. The air crackles with unnatural energy, and the water itself seems to pulse like a heartbeat. Deep within, an Elder Froghemoth reigns supreme, and its presence has accelerated the spawning of younger froghemoths. The swamp churns with these alien horrors, each threatening to spread beyond the swamp’s borders and overtake the surrounding lands.
Why the Swamp Must Be Stopped
The Froghemoth Elder has begun spawning at an alarming rate, its alien biology infusing the swamp with strange, otherworldly magic. If left unchecked, dozens—perhaps hundreds—of froghemoths will emerge, spreading devastation to the nearby towns and cities. The adventurers must venture into the swamp to halt this spawning process before it’s too late.
Adventure Objectives
To defeat the Froghemoth Swarm, the adventurers will need to accomplish several objectives:
- Locate the Spawning Grounds
- The adventurers must find the Elder’s lair deep within the swamp. This requires navigating treacherous terrain filled with hazards like quicksand, carnivorous plants, and deadly amphibious predators.
- They might encounter clues such as damaged boats, giant eggshells, or terrified survivors who fled the swamp.
- Disrupt the Spawn Pools
- The Elder has created magical spawning pools where its offspring are rapidly gestating. These pools bubble with alien energy, and froghemoth eggs litter the area. The party must destroy or disrupt these pools before the eggs hatch.
- Possible challenges include:
- Guarding froghemoths protecting the pools.
- Environmental hazards like collapsing terrain, poisonous gas, or enchanted swamp water.
- A timed challenge where eggs begin to hatch during combat.
- Confront the Elder
- The final confrontation pits the adventurers against the Elder Froghemoth in its lair. Surrounded by unhatched eggs and smaller froghemoths, the battle is a chaotic, high-stakes encounter.
- The Elder might use the spawning pools to heal itself or empower its offspring mid-battle, forcing the players to multitask between battling the Elder and destroying the pools.
The Swamp Environment: Living Danger
The Swamp of Spawn is as much a foe as the froghemoths themselves. Consider using the following environmental features to keep the tension high:
- Shifting Terrain: Paths through the swamp aren’t stable. Some sink into the muck, while others give way to deep water filled with lurking threats.
- Alien Flora: The swamp’s plants have been mutated by the Elder’s presence. Some release toxic spores, while others lash out like living tentacles to ensnare the unwary.
- Egg Hazards: The ground is littered with froghemoth eggs. Stepping on them could spawn a small, aggressive froghemoth spawn (use stats for a Giant Toad but give it resistance to fire and lightning).
Combat Encounters
Ambush in the Muck
- A small group of froghemoths waits beneath the swamp’s surface, hidden among the reeds and brackish water. When the adventurers pass through, the creatures attack in a coordinated ambush, using their Tentacle and Tongue actions to drag adventurers into the water.
Defending the Pools
- At each spawning pool, the adventurers must face a group of froghemoths and other swamp-dwelling creatures like giant frogs, crocodiles, or elementals summoned by the magical pools.
- Add a timer mechanic: For every 3 rounds the adventurers spend at the pool, one froghemoth egg hatches, spawning a hostile creature.
Final Showdown with the Elder
- The Elder fights to protect its brood, using the swamp environment to its advantage. It might leap onto unstable platforms, causing them to sink, or use its Alien Gaze to confuse and terrify the party.
- Smaller froghemoths could join the fight at intervals, forcing the players to split their attention.
- As the fight progresses, the Elder might try to retreat into one of the spawning pools, healing itself and forcing the players to finish the fight before it can recover.
Adventure Rewards
Defeating the Elder Froghemoth and destroying the spawning pools should feel like a monumental achievement. Here are some possible rewards:
- Froghemoth Scale Armor: A suit of armor crafted from the Elder’s hide, granting resistance to fire and lightning.
- Swamp Heart Amulet: A magical item that allows the wearer to breathe underwater and move through difficult terrain without penalty.
- Elder’s Essence: A vial of glowing liquid harvested from the Elder that acts as a potion of giant strength or a material component for powerful spells.
- Heroic Renown: The party’s victory earns them fame across the region, with locals hailing them as saviors and offering future aid.
Final Thoughts
The Swamp of Spawn is a perfect opportunity to showcase the Froghemoth Elder as both a creature and a world-building element. It combines tense exploration, brutal combat, and environmental hazards into one unforgettable adventure. Whether your players are battling to save a village or venturing into the swamp for their own reasons, this scenario is sure to deliver thrills, chills, and plenty of oozy, alien mayhem.
