Not sure why, but regardless of charms or anything of the sort the conjurer is incapable of spawning passive mobs (chicken, sheep, cow, etc.). I'm playing with a self-made modpack for me and my brother and we are in 1.19.2 .

Exactly like a vanilla spawner, the Conjurer requires the mob's spawn conditions to be met. In the case of passive mobs this means two things:

• it has to be surrounded by grass
• there needs to be sufficient light (level >7 I believe)

Does your setup meet those requirements?

This worked, thank you, thank you. We had it in a stone enclosure and it never occurred to me even when I tested in creative to try this. Thanks again.
