Loot Sharing

Loot Sharing is a mechanic which allows multiple players to receive drops from enemies.

Mechanics
If multiple players deal of  to a mob, or  of  to a Slayer boss, and are within  blocks of the mob when it dies, the top 5 damagers will receive drops from the mob. The message that appears when Loot Sharing works is: Mobs can have unique loot pools for Loot Sharing, which are used instead of their regular loot pools if the player Loot Shares. They usually have lower amounts of items or lower drop chances for rare items. Drops from Loot Share loot pools are rolled based off of the player's and, and are not affected by  or.

Loot Sharing works with all mobs, except on the Private Island and in Dungeons. The Vanquisher does not have a cap on the amount of players that can receive loot from it.

This mechanic was implemented to ease the killing of mobs on the Crimson Isle, as they have multiple millions of there. Loot Sharing was first only implemented for Ghosts, however with the 0.13 update, this was changed so that any mob in the game could be loot shared.
