I tryed to give myself a sculk shrieker that can spawn a warden. Whatever I do I can't use /give to optain a skulk shrieker that can spawn a warden, it just keeps giving me normal sculk shriekers that can't spawn a warden. Even with an item editor it is not possible to obtain a sculk shrieker that can spawn a warden, since the sculk_shrieker is reset to a non warden spawn one when it is optained in item form. The screenshot is from a minecraft wiki, it tells me that the sculk shrieker that can spawn the warden is not obtainable, because the code for the item form of the warden spawn sculk shrieker is missing.
