This potion will be useful when dealing with the Warden mob because this potion effect will eliminate every sound the player makes, whether be it placing blocks, footsteps, or attacks. To make this potion, you'll need awkward potion and a new item that is dropped by the Warden itself. The potion effect should last for only 20-35 seconds to keep game balance. The status effect should be called "Silence." This won't only be useful to Wardens, this will also be useful when sneaking through players as well if you want to mess with them, that is. Mobs with this status effect will also make no sounds so it would be very useful to when making maps or minigames. Sculk sensors would also not be able to detect you with this status effect. The item that is used to make this potion will be up to you developers because I can't really think of an item what the Warden would drop. (I know the Warden is attracted to vibrations but eliminating sounds I think should also be effective to avoid the Warden).
