I want to use the Message cantrip to coordinate with an ally in secret. However, I want to do this during a loud battle (powerful spells being flung back and forth in a highly destructible environment). The text of the spell says:
You … whisper a message. The target … hears the message and can reply in a whisper that only you can hear.
Since the message is whispered, does that mean the target may not be able to make out what I'm saying over the din of battle? Or does "the target hears the message" imply that the spell's magic ensures that the message is audible?
Best Answer
Yes, the target hears the message, even if there are other ambient noises.
The message spell is a magical effect, and doesn't actually create a sound as per normal speech. Instead, only the target hears it.
As you can imagine, this isn't how sound works according to conventional physics. But it's magic, and magic generally doesn't care about the laws of nature.
However, the message spell requires a verbal component to cast. If something prevents the spellcaster from performing the verbal component, then the spell would fail.
If something prevents the caster from whispering the message, then it's likely that they can't perform the verbal components for the message cantrip either.
