Note that these changes require manually updating or deleting your config to be fully utilized

  • Added a /grim history command that shows you historical flags players have triggered
  • Split Reach into 4 seperate checks
    • Reach - checks if they hit from too far (known to be unfalsable)
    • HitboxMiss - checks if player missed the target entity hitbox (very rarely falses)
    • HitboxBlock - checks if a player hit an entity through blocks (no known falses)
    • HitboxEntities - checks if a player hit an entity through another entity - (falses uncommonly)
  • Improved HitboxEntities to check through entities in Vanilla's iteration order, reducing false rate significantly especially in swarms of mobs or team fights. Note that this check is disabled by default.
