1-level Illusion (ritual)
You twist the tongues of up to 4 creatures within range, causing
their speech to be disguised as incomprehensible, illusory
babbling. No creature except the caster can understand the
target, hearing any auditory expression as unintelligible garble.
However, targets of the spell may still communicate as normal to
one another, as long as each of them were subjected to the
effects of incomprehensible language by the same creature.
An unwilling target can make an Intelligence saving throw,
avoiding the effects of the spell on a success.
A creature under the effects of the comprehend languages
spell can understand targets of this spell. Additionally, casting a
tongues spell on a creature under the effects of this spell ends
the effects of incomprehensible language.
