Tongues (spell)

Tongues is a spell that lets the caster understand and speak the language of any creature, living or dead. This includes idioms and elements like sarcasm or general intent. While the spell is active, the caster can converse with as many people as are within the area of effect, and in as many languages as needed.

Similar to comprehend languages, the casgter can also grasp writings and symbols, even long-dead languages. The spell allows for understanding coded material and ciphers.

However, the caster cannot share the effects with another person, and the spell can't be used to communicate with creatures with less than 5 intelligence or those creatures that don't possess a language.

Reverse: Babble

The reverse of the spell, Babble can be cast on recipients within a range of 30 ft. Affected individuals are allowed a saving throw against magic; if this fails, the individual will be utterly incapable of understanding the speech or writing of others, or able to write or speak coherently themselves for the spell's duration.

Bringing the Spell into Play

Players should consider using the spell not only when conversing with those who speak a different language but particularly when addressing individuals from unfamiliar cultural or hierarchical backgrounds. It can help prevent social mishaps by masking one's lack of etiquette, uncouth demeanor, or differences in education compared to their peers.

The spell allows characters to adapt their speech to the level of their audience, whether they are addressing kings or criminals, scholars or commoners. Although the duration is short, the spell allows the caster to be as eloquent or casual as the situation demands, quickly establishing rapport with the listeners and making them feel comfortable, treating the caster as if he or she were "one of their own."
