DM "the tarrasque attempts to bite you, and the ancient red dragon breathes fire at you."

sorcerer "i cast "oh no you didn't""

DM "ok, you now have disadvantage on your roll to dodge the fire, and the tarrasque has advantage on its roll to hit you."

sorcerer "thats not how it works!"

DM "you read the spell's description, right? they (in this case meaning you, because it never said otherwise) has disadvantage, and other (in this case meaning me, it never specified) has advantage. wizard, your turn."

Instead of "They roll d20 use lower" the term is has disadvantage

although that's just me being pedantic :/

try using they have disadvantage on their next ____ roll maybe.

also, maybe use "Other creatures then have advantage on their attack rolls and advantage on ability rolls or saving throws related by the affected creature within 1 min"
