In addition to the first egg that vanilla Minecraft spawns, each time a player unlocks the "Free the End" advancement, this mod drops an addional egg for them.
Intended for use on multiplayer servers to prevent players from being locked out of having a dragon egg just because they were a bit late to the party. Unlike other mods that spawn an egg every time the dragon is killed, this mod keeps eggs as a finite, valuable trophy by only spawning an egg when a player gets the "Free the End" advancement, limiting it to only one extra egg per player.
