Other Planes and Effects
Below is information about this spell as it relates to other planes and area of effects (i.e. underwater). Some of the information is pulled official D&D sources (such as books and the twitter feeds of D&D officials), but other information is derived from forums and online discussions. As always, it is up to the DM to decide how they wish to handle spell effects.
Underwater - Verbal Component
Official rules have been verified by Jeremy Crawford - "No rule prohibits verbal components from working underwater. Keep in mind that if you're talking, you're not holding your breath." Hence, while submerged underwater and holding its breath, a creature can cast a spell that requires a verbal component. After casting the spell, if the creature can't breathe underwater, it immediately runs out of breath. The creature can survive for a number of rounds equal to its Constitution modifier (minimum of 1 round).
