Greetings! Would you care to roll a die or two?

Pleeease go ahead and roll some dice for my mental enrichment, and also your own.
Some of my favourite spells to try are:

Magic Missile: Fires 3 individual homing darts each of 1d4+4 force damage.

Lightning Bolt: Each creature in a 100ft line makes a dexterity saving throw against 18.
They take 8d6 lightning damage on a failed save, and half on a successful throw.

Incindiary Cloud: Each creature in a 20ft sphere makes a dexterity saving throw against 18.
They take 10d8 fire damage on a failed save, and half on a successful throw.
