    • monster_spawn_block_light_limit is an integer controlling the block light needed to prevent monster spawns.
    • monster_spawn_light_level is an int provider which is evaluated to find a value to compare the current overall brightness with to determine if a monster should be allowed to spawn.
Mangrove Swamp
  • Slightly reduced the number of mangrove trees (25 attempts per chunk to place a tree, down from 30).


  • The parent advancement of the "It Spreads" advancement is changed from "Adventure" to "Monster Hunter".

Realms is not compatible with snapshot versions.".
