Make an amethyst throwable (to distract Wardens)

The amethyst throwable would be a sort of sparkler. You throw it like a snowball, and where it lands, a bamboo shoot with an amethyst tip will spawn. 

How would it work?

The sparkler will be there for about 12 seconds before despawning. During those 12 seconds, the sparkler would make a constant noise that disables the Warden's ability to hear you. IF the Warden already had seen you, or you hit it, the sparkler's effect will not work/stop working.

How would you make it?

The sparkler would be made from 2 amethyst, a fire charge, a bamboo and a piece of string.

Why should it be in the game?

The sparkler would give a bit of breathing room against the Warden, making it easier to traverse; however, since it is rather expensive, it is not something you would be obtaining early on (balances it out)
