Where you roll 12d6 in D&D

Sunburst and Delayed Blast Fireball: Sunburst is an 8th-level spell with a huge 60-foot radius. Everything inside makes a Constitution save, taking 12d6 radiant (42 on average) and going blind for up to a minute on a failure, or half damage on a success. In the 2014 rules undead and oozes have disadvantage on that save. Delayed Blast Fireball, a 7th-level spell, starts at 12d6 fire and gains 1d6 at the end of each of your turns while you hold it, so a bead that lasts through the end of two of your turns explodes for 14d6. Plant it, hold it, and let enemies walk into it.

Fireball and Prismatic Spray: Fireball starts at 8d6 and gains 1d6 per slot level, so a 7th-level slot makes it 12d6. Prismatic Spray rolls a d8 for each creature to pick its ray; in the 2024 rules the damaging rays deal 12d6 of their own type, while in the 2014 rules they dealt 10d6.

Young green dragon: A young green dragon's Poison Breath covers a 30-foot cone with 12d6 poison (DC 14 Constitution save, half on a success). That averages 42, or about 21 for characters who save, which is often more than a 5th-level wizard's whole hit point total. On 12d6 you roll 50 or more 10.36% of the time and 48 or more 17.83% of the time. Use the encounter calculator before you drop one on a mid-level party.
