LevelZ+

LevelZ+ 2.1.2+mc1.20.1
Full cooperative progression XP to each player who successfully damages an enemy and remains alive and continuously connected until it dies. Rewards are not split and killing blows are not required.
Persistent first-hit contributor records across enemy unload/reload. Unlimited contributors, no contribution timeout, no offline XP queue.
Death and disconnection permanently invalidate eligibility for the current enemy, including if the player attacks it again after respawning or reconnecting.
Expanded hit attribution for projectiles, TNT, tamed entities and multipart Ender Dragon damage.
Configurable base-mob-XP multiplier, maximum-health XP bonus, per-contributor percentage and separate Dragon multiplier.
Preserves LevelZ spawner and gamerule exclusions and the independent LevelZ XP pool.
Updated generated configuration and metadata for general public use. Fresh installs default to shared XP disabled to avoid double native LevelZ XP; existing config values are preserved.
Maintains all previous LevelZ+ stat bonuses and optional mod integrations.
