🌊 Racial Variants #
| Variant | Name | Description |
|---|---|---|
| Elven | Aqueous Grace | Elves move with a liquid efficiency. They calculate underwater movement in yards rather than feet, allowing them to traverse the depths at the same speed as the surface. |
| Dwarven | Lead-Belly Sink | Dwarves are naturally dense. They treat the first 600 cn of encumbrance as if it were only 400 cn for the purpose of being dragged down, but they take a -4 penalty to all Strength checks made to stay afloat in rough water. |
| Halfling | Cork-Buoyancy | Halflings are naturally buoyant and difficult to submerge. They receive a +4 bonus to their first check to avoid slipping under the water, and they ignore the “Panic” penalty for holding their breath. |
| Lizardfolk | Tail-Propulsion | Biological masters of the water. They can hold their breath for twice their Constitution score. Additionally, they can “Sprint” underwater for 1d4 rounds at their full outdoor running speed. |
🗺️ Regional Variants #
- The Pearl-Diver (Coastal/Island)
Trained in the lung-bursting discipline of deep-sea harvesting.
- Specialty: Carbon-Dioxide Tolerance. When they reach the stage of making Constitution checks to keep from drowning, they do not suffer the cumulative +1 penalty until the fourth round, representing incredible lung capacity.
- The River-Raft Guard (Wilderness/Riverlands)
Trained to survive the violent, unpredictable “White Water” of mountain rapids.
- Specialty: Hydraulic Intuition. They gain a +4 bonus to Strength checks made to battle high seas or rough currents. They know how to “read” the water to find the eddies that keep their head above the surface.
- The Sewer-Shambler (Metropolitan/Urban)
Trained to swim in the thick, buoyant, and toxic “Sludge” beneath the capital.
- Specialty: Contaminant Resistance. They are immune to the “Stun” or “Nausea” effects of swallowing foul water while drowning. They can also treat 400 cn of encumbrance as 200 cn if the liquid they are in is high-density (mud or sewage).
- The Ice-Floe Survivor (Arctic/High Altitude)
Trained to survive the “Heart-Stop” cold of glacial meltwater.
- Specialty: Cryo-Stasis. When they reach the “Halfway between life and death” state, they remain in that state for a number of rounds equal to half their Constitution score (instead of 1/3), as the cold preserves their vital organs.
⚓ The Mechanics of the Deep #
As per your provided rules, the “Drowning Clock” is a terrifying progression. Here is the Official Survival Flow:
- The Drag: If carrying >400 cn, make a Strength Check every round. Failure = Slip Under.
- The Breath:
- Calm: Rounds = Constitution Score.
- Exertion (Fighting/Panic): Rounds = 1/2 Constitution Score.
- The Struggle: Once breath is gone, roll Constitution every round.
- Round 1: Flat Con Check.
- Round 2+: Cumulative +1 penalty to the die per round.
- The Twilight: Failure = Drowned (but not dead).
- Duration: 1/3 Constitution rounds.
- Rescue: Requires Healing Skill or Magic.
- The End: Death (Requires Raise Dead).
⚖️ Synergy with Other Skills #
- Swimming + Athletics: A successful Athletics check allows a character to carry an unconscious ally while swimming without the ally’s weight counting toward the 400 cn “Drag” limit.
- Swimming + Fishing/Nature Lore: The character knows how to find “Air Pockets” in submerged caves or shipwrecks, allowing them to reset their “Breath Clock” without surfacing.
- Swimming + Military Tactics: The character can coordinate a “Submerged Ambush,” allowing a group to remain underwater and strike with a +2 bonus to surprise.
