This spell gives an untrained swimmer the ability to swim as if proficient, with all chances for success detailed in the Player's Handbook under the description of the swimming nonweapon proficiency. If cast on a proficient swimmer, the recipient swims with a + 2 bonus to his or her Constitution for purposes of determining success. One creature for every two experience levels of the spell's caster (round up) can be affected.
The material component is a small pumice stone for each recipient.
