I know sculk shriekers placed by players don't summon warden but they don't give players the darkness effect as well.This is vital for the "How Did We Get Here?" advancement,as if only natural-generated sculk shriekers can give darkness effect,this advancement will almost be IMPOSSIBLE to complete.Just imagine transport shulkers and dolphins to deep dark biome from thousands blocks away whilst not killed by warden.That's extremely painful and annoying.Otherwise please consider add some relatively easier ways to get the darkness effect such as darkness potion/arrow/suspicious stew.Thank you very much.
