How It Works

1

2

Specify Armor & Proficiency

Indicate whether the creature is wearing heavy armor and if it possesses proficiency with that armor type.

3

Declare Racial Swim Speed

Toggle if the creature has a natural racial swim speed and, if so, input the specific value in feet.

4

Receive Calculated Speed

The tool processes all inputs according to 5e rules and provides the final swimming speed along with a clear explanation of the calculation.

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.
