Ok so I should know the answer to this but I am a bit weary due to other factors that may or may not matter. So I have a tier 6 blood altar with well of suffering under it. I am using the draconic spawner maxed out too spawn witches. So far I have only seen 9 witches spawn in total. I also have cursed earth 4-5 blocks down allowing room for another spawn level. Nothing spawns on the cursed earth at all and the max upgrade draconic spawner will not output more than 9 at a time. I was wondering more about the botania sparks than anything else. A botania spark is considered an Entity if I am not mistaken. Does having these sparks in or around the same area as my blood magic altar effect the spawn rate at all? I have not done any testing on this but probably should. I know there is a cap per chunk on spawn/ratios, Not exactly sure what the cap would be on crackpack or if it can be increased just a tad. Seems a bit low for only 9 mob spawns at a time. Thoughts on this?
Yes but are sparks entities and if so shouldn't they also be excluded? I guess it depends on how the mob limiter is written. Maybe sparks are not suggested as entities. I will have to do some testing on it to find out. I don't think they are.
