Message
You point 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. You can cast this spell through solid objects if you are familiar with the target and know it is beyond the barrier. Magical silence; 1 foot of stone, metal, or wood; or a thin sheet of lead blocks the spell.
Message 5e 2024 vs. 2014 edition differences
The 2024 version removes verbal components, adds druid as a class, simplifies the description of barriers ("magical silence; 1 foot of stone, metal, or wood"), and clarifies that the spell can be cast through solid objects if familiar with the target. Duration and range remain the same.
