Tips to Get the Most Out of 5e swimming speed
Verify Base Stats
Always double-check the creature's official base walking speed and any inherent racial traits before inputting to ensure the most accurate calculation.
Understand Heavy Armor Nuances
Remember that the heavy armor penalty (halving speed) only applies if the creature is *not proficient* with that armor. Proficiency negates this specific swim speed penalty.
Prioritize Racial Abilities
If a creature has an explicit racial swim speed (e.g., Tritons, Lizardfolk), this speed is generally used instead of halving their walking speed, though heavy armor penalties can still apply to it.
