Sculk Powder

This can be a dust that has a chance to be dropped when mining a sculk block, such as a sculk sensor, sculk block, sculk catalyst, sculk shrieker, and sculk vein with the the intended tool for mining the block.

When the sculk dust is in your main hand you can right click, you will lose 1 dust, and you will get an effect that will allow the warden to not be able to smell you for at least 1 minute.

This could come in handy if you make noise and have no distractions for the warden, especially if in Hardcore.

It would probably smell bad so when used it can give off a few seconds of nausea.
