Chromatic Gamble

You launch a sphere of energy at a point within range. Each creature in a 30-foot-radius sphere centered on that point must make a Constitution saving throw. A target takes 5d6 damage on a failed save, or half as much damage on a successful one. The sphere spreads around corners. The damage type is your choice of acid, cold, fire, lightning, poison, or thunder.

Lucky Rolls. Depending on the result of your damage dice roll, the spell may perform one of the following additional effects. If a creature that passed its saving throw takes damage from one of these additional effects, that damage is halved. If the roll fulfills the requirement for more than one effect, you choose which effect takes place:

3 of a kind. If the same number is rolled on three of the damage dice, you may roll an additional 3d6 damage of the type you chose and apply it to one target of your choice that took damage from the spell.

4 of a kind. If the same number is rolled on four of the damage dice, you may roll an additional 4d6 damage of the type you chose and apply it to one target of your choice that took damage from the spell.

Full House. If one number is rolled on two dice and a different number is rolled on three dice, such as rolling 2 threes and 3 fives, you may deal 5 additional damage to every creature that took damage from the spell.

Small Straight. If sequential numbers are rolled on four of the damage dice, such as a 2, a 3, a 4, and a 5, you may deal 6 additional damage to every creature that took damage from the spell.

Large Straight. If sequential numbers are rolled on all of the damage dice, such as a 1, a 2, a 3, a 4, and a 5, you may deal 8 additional damage to every creature that took damage from the spell.

Critical Luck. If the same number is rolled on all five damage dice, you may reroll all five dice and add the new total to the spell’s damage. This second roll cannot trigger any of the additional effects listed except for triggering another Critical Luck.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the radius increases by 5 feet for each slot level above 3rd.
