Minecraft wiki entry for Exploring_an_ancient_city, associated text: When a player approaches a patch of sculk blocks, the first thing they want to do is to count how many sculk shriekers there are. If there is just one shrieker, this makes the task quite easy. The player simply needs to sneak up to the shrieker and break it with their hoe – even though this triggers the sculk sensors nearby, no wardens will spawn since there are no more shriekers nearby that can spawn it.
