Water Breathing: solve respiration without assuming a Swim Speed

SRD 5.2.1 · Spell decisions

Before casting

At the table

1. Choose up to ten willing creatures within 30 feet.
2. Each gains underwater breathing until the spell ends and retains its normal mode of respiration.
3. Plan movement and other hazards using their own rules; this spell does not list a new Swim Speed or a general protection from underwater danger.

Example decision

An affected creature has no Swim Speed. Does Water Breathing itself give the creature a Swim Speed equal to its ordinary Speed?

No; the listed benefit is breathing, not a Swim Speed.

The spell grants underwater breathing while preserving normal respiration. It does not state that it changes Speed or grants a Swim Speed. Use the creature’s existing movement capabilities and the Swimming rule when calculating its route. The long duration makes breathing less urgent, but does not replace other parts of travel planning.

Watch for this mistake

The target limit is up to ten willing creatures within range, not every creature who later joins the group. Also retain the normal breathing benefit when describing a return to air.

Ask the table

Who is included in the casting, and which underwater obstacles remain after breathing is solved?
