The bard composes a sea shanty.
The fighter sharpens his sword.
The wizard prepares a speech about buoyancy physics he read on a forum at 3:00 AM.
The rogue realizes sneak attack requires not drowning.
The cleric discovers healing word does not cure lack of oxygen (or does it?).

Welcome to underwater combat, where your character sheet becomes a flotation device and the real boss monster is physics.
Show Notes
In this episode the RPGBOT crew dives into underwater combat in tabletop RPGs (especially D&D 5e’s mechanics), exploring how the environment radically changes tactics, character builds, spell effectiveness, and encounter design. From fighting sea monsters to exploring sunken cities, the episode focuses on helping both players and Dungeon Masters survive combat in aquatic environments.
The hosts discuss how underwater encounters fundamentally alter normal assumptions about combat: movement slows, weapon effectiveness changes, ranged attacks suffer, and suddenly everyone cares deeply about breathing. Holding your breath and weapon limitations become major survival mechanics, sometimes more dangerous than the enemies themselves.
They also cover adventure design inspiration from nautical campaigns and aquatic modules, emphasizing that underwater sessions feel memorable because they force players to rethink their habits. Instead of pure damage math, success often depends on preparation, environment-appropriate gear, teamwork, and creative problem solving.
The episode balances mechanical analysis with humor, especially the universal tabletop experience of realizing too late that your character was designed exclusively for land combat and is now essentially a confused housecat thrown into the ocean.
Ultimately, the crew frames underwater encounters as a powerful storytelling tool: when used intentionally, aquatic combat becomes less about hit points and more about tension, creative problem solving, and environmental immersion.
Key Takeaways
- Underwater combat changes the meta: normal D&D 5e tactics don’t always work the same way.
- Breathing mechanics and suffocation rules can be deadlier than monsters.
- Many weapons and ranged attacks are dramatically less effective underwater.
- Spell choice matters. Some spells become amazing while others become useless.
- Movement restrictions force teamwork and positioning strategy.
- Preparation (gear, magic, planning) beats raw DPR optimization.
- Aquatic encounters create memorable sessions because players must adapt.
- Environmental storytelling works best when mechanics reinforce danger.
- DMs should telegraph danger so failure feels fair, not arbitrary.
- Randall should not be trusted with physics experiments.
