Weight = spawn weight of the mob in its category · Chance = weight ÷ total weight of the category · Group size = how many spawn together.
In Java Edition 5 mob types can spawn in Nether Fortress — hostile mobs: Blaze, Wither Skeleton, Zombified Piglin, Magma Cube and Skeleton.
Blaze has the highest spawn weight among the hostile mobs: 10 of 28 (35.7%) in Java Edition.
Yes. Java Edition lists 5 spawn entries for Nether Fortress, Bedrock Edition 5. Use the edition switch above the tables to compare.
Each spawn attempt first picks a category (for example hostile or passive mobs), then one mob of that category at random, weighted by its spawn weight. A mob's chance is its weight divided by the total weight of its category in the biome — so the shares in each table add up to 100%.
