Banshee scream

A Banshee's scream is know to deal a lot of damage, deafen and sometimes even kill creatures.

The banshee screams in a 15 ft. cone or a 30 ft. line by 5 ft. wide. The scream can be heard up to 300 feet.
The creatures that stand in that cone or line have to make a constitution saving throw.

(Spell DC = 8 + proficiency bonus + charisma modifier from the banshee or caster)

If they succeed = they take half damage and are deafened for half a minute.
If they don't succeed=  they take full damage and are deafened for one minute.

Creatures that rely on their hearing to be able to see or also blinded just as long as they are deaf.

The scream can break class, wooden walls and even strong doors or gates.
