Voice Change

You magically alter your voice. You can choose a humanoid you have heard before, and your voice resembles theirs. However, any speech patterns or accents may be up to your abilities, and to copy a voice, you must know the language. An Intelligence check against your spell save DC may reveal the voice being made magically. As an action while the spell is active, you can change your voice to another individual or choose one of the following:

Bestial Sounds. You adopt the sound of a beast you have encountered before and mimic it exactly.

Devious Voice. Your voice resembles a creature that belongs to the underworlds and dark corners of the world. If you have encountered a fiend before, you can mimic its speech pattern, but you must know a language spoken by the fiends. It lasts for up to 1 minute, then the spell ends.

Angelic Tone. Your voice resembles an angelic creature of celestial origin. If you have encountered a celestial before, you can mimic its speech pattern but you must know a language spoken by the celestials. It lasts for up to 1 minute, then the spell ends.

Private Speech. You choose creatures up to your spellcasting ability modifier. When you speak, only they understand what you say exactly while other creatures around hear the words you choose. For each minute passed in private speech, you must make a DC 10 Constitution saving throw to be able to continue the spell. Each minute increases the DC by 1.
