Experience Orbs (or Points) are small, glowing orbs that, when gathered, can total up to experience levels that are required for enchanting or for repairing items in an anvil. Experience points were added to Minecraft during the first part of the Adventure Update.
Experience orbs are entities in Minecraft which are spawned when a player kills a mob. Experience orbs are most commonly seen as green or yellow and float toward the player up to a distance of 7.25 blocks, speeding up as they get nearer to the player. These orbs can be obstructed by other elements like cobwebs or currents. A spawned orb can follow a player for 5 mins after its birth which can lead to a swarm of orbs following the player. They make a distinct bell-like sound when picked up by a player.
Experience orbs are formed when a player kills a hostile spawn or mob. They gravitate towards the player and add to their experience level (which is shown on the bottom of the screen). Bigger creatures leave bigger and denser orbs after their death, like the ender dragon which leaves orbs worth 17 points and more.
Experience levels are now an indicator of how well-versed a player is in the game. Experience orbs are a well deserved reward for winning battles against hostile mobs. The update where players can repurpose these orbs was greatly supported as it opened up a lot of new avenues to showcase talent.
