I've been thinking about getting Knock anyways because I think thats just a really fun spell for a Bard to have. Like, "Oh we need this door open well allow me! Knock!!!!!!" and it bellows everywhere. But obviously that sound can be detrimental.
Knock can be heard from 300 ft away.
If I cast Silence on the locked item/door prior to casting Knock would the sound be silenced within the sphere but still heard outside of it (dampened) or would that make it not heard at all (muted)?
