Loot or lewt is an item or currency “dropped” by a defeated creature in an online game. For example, an NPC (non-player character) in an MMORPG may drop a weapon that can be equipped and used by the player who killed it.

The rarity of the loot is often associated to the difficulty of the creature being killed. For example, a boss that requires multiple people to kill has rarer loot because of its difficulty.
