Save: Constitution
Two creatures you can see within range must make a Constitution saving throw, with disadvantage if they are within 30 feet of each other. Either creature can willingly fail the save. If either save succeeds, the spell has no effect. If both saves fail, the creatures are magically linked for the duration, regardless of the distance between them. When damage is dealt to one of them, the same damage is dealt to the other one. If hit points are restored to one of them, the same number of hit points are restored to the other one. If either of the tethered creatures is reduced to 0 hit points, the spell ends on both. If the spell ends on one creature, it ends on both.

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).
