Lesser Zone of Euphemisms (5e Spell)
From D&D Wiki
|Casting time:||1 action|
Twisting the framework of communication itself, you create a space where proper etiquette is compulsory.
You make a 30-ft-radius magical zone within range. Creatures within the zone that attempt to say something rude, vulgar, and/or hostile are compelled to phrase it in a civil manner. For example, if a warrior attempted to yell "I'm going to kill you, tree-hugger!" at an enemy druid, he might instead say "I would personally prefer it if the nature enthusiast passed away." Abyssal and Infernal cannot be spoken or heard.
This effect extends to writing as well—any text that includes rude, vulgar, and/or hostile language becomes neutral in tone while within the zone. Rude gestures can be made, but the portion of the creature's body which makes the gesture is visually censored. Likewise, paintings and drawings which would be considered offensive are also visually censored.
If vicious mockery is cast by or on a creature in the zone, the spell fails.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the duration doubles for every slot level higher than 3rd. For example, using a 7th-level spell slot would double the duration by four-fold.
