Damage Type: Radiant
Save: Constitution
A silvery beam of pale light shines down in a 5-foot-radius, 40-foot-high Cylinder centered on a point within range. Until the spell ends, Dim Light fills the Cylinder, and you can take a Magic action on later turns to move the Cylinder up to 60 feet.
When the Cylinder appears, each creature in it makes a Constitution saving throw. On a failed save, a creature takes 2d10 Radiant damage, and if the creature is shape-shifted (as a result of the Polymorph spell, for example), it reverts to its true form and can't shape-shift until it leaves the Cylinder. On a successful save, a creature takes half as much damage only. A creature also makes this save when the spell's area moves into its space and when it enters the spell's area or ends its turn there. A creature makes this save only once per turn.
The damage increases by 1d10 for each spell slot level above 2.

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).
