[RPG] Can the whisper of a Message spell be heard over loud ambient noise


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.

You point your finger toward a creature within range and whisper a message. The target (and only the target) hears the message and can reply in a whisper that only you can hear.

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 you can’t provide one or more of a spell’s components, you are unable to cast the spell. [...] Thus, a character who is gagged or in an area of silence, such as one created by the silence spell, can’t cast a spell with a verbal component.

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.
