Duration: Concentration
, up to 1 minute
Damage Type: Fire
Save: Dexterity
A beam of yellow light flashes from you, then condenses at a chosen point within range as a glowing bead for the duration. When the spell ends, the bead explodes, and each creature in a 20-foot-radius Sphere centered on that point makes a Dexterity saving throw. A creature takes Fire damage equal to the total accumulated damage on a failed save or half as much damage on a successful one.
The spell's base damage is 12d6, and the damage increases by 1d6 whenever your turn ends and the spell hasn't ended.
If a creature touches the glowing bead before the spell ends, that creature makes a Dexterity saving throw. On a failed save, the spell ends, causing the bead to explode. On a successful save, the creature can throw the bead up to 40 feet. If the thrown bead enters a creature's space or collides with a solid object, the spell ends, and the bead explodes.
When the bead explodes, flammable objects in the explosion that aren’t being worn or carried start burning.
The base damage increases by 1d6 for each spell slot level above 7.

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).
Underwater - Fire Effects
The PHB p198 clearly states "Creatures and objects that are fully immersed in water have resistance to fire damage." Other than that, there are no official rules regarding fire spells underwater. But, as always, it is always up to the DM to decide if fire spells should have different effects (i.e. half range, half area of effects, half duration, etc.). In addition, Jeremy Crawford has clearly stated, regarding a fireball vaporizing water, "Nothing in the rules causes a fireball to vaporize water. Magic ≠ physics. DMs may apply whatever magical/scientific logic they like."
