(- Warden -- Wardens do not use standard mob spawning mechanics. They are instead spawned when a player activates naturally generated sculk shriekers four times and if there isn't already another warden within 24 blocks of it. A warden spawns by emerging from the ground near the shrieker that summoned it, taking about 6.7 seconds to do so and being completely invulnerable until fully emerged. - Wither -- The wither is spawned by placing 4 blocks of soul sand and/or soul soil in a T shape (see image on the right in the "Behavior" section), and putting 3 wither skeleton skulls on top of the three upper blocks. The last block placed must be one of the three skulls and can be placed by the player or a dispenser. Air blocks are required on either side of the base soul sand or soul soil under the upper blocks (non-solid blocks such as grass and flowers prevent the wither from spawning). The building pattern can have any orientation (including horizontal and upside-down) as well as the skulls; the wither always spawns at the foot of the pattern. When the wither has successfully spawned, it is angered and creates an explosion around itself. -)
