Duration: Concentration
, up to 1 minute
Damage Type: Psychic
Save: Intelligence
You attempt to craft an illusion in the mind of a creature you can see within range. The target makes an Intelligence saving throw. On a failed save, you create a phantasmal object, creature, or other phenomenon that is no larger than a 10-foot Cube and that is perceivable only to the target for the duration. The phantasm includes sound, temperature, and other stimuli.
The target can take a Study action to examine the phantasm with an Intelligence (Investigation) check against your spell save DC. If the check succeeds, the target realizes that the phantasm is an illusion, and the spell ends.
While affected by the spell, the target treats the phantasm as if it were real and rationalizes any illogical outcomes from interacting with it. For example, if the target steps through a phantasmal bridge and survives the fall, it believes the bridge exists and something else caused it to fall.
An affected target can even take damage from the illusion if the phantasm represents a dangerous creature or hazard. On each of your turns, such a phantasm can deal 2d8 Psychic damage to the target if it is in the phantasm's area or within 5 feet of the phantasm. The target perceives the damage as a type appropriate to the illusion.

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).
