The Ancient Entity is spawned by using a Mysterious Clock anywhere in the Overworld. There are no restrictions on exactly where in the Overworld the Ancient Entity needs to be spawned, allowing the player to spawn it in highly advantageous conditions such as inside blocks, in lava, or other forms of traps. The Ancient Entity cannot be summoned on Peaceful difficulty.
Upon usage of the Mysterious Clock, the Ancient Entity immediately spawns at full health. It will slowly approach any player within range until attacking when close enough. The Ancient Entity's melee attack will damage the target and launch them 19 blocks into the air. The damage of the Ancient Entity's melee attack depends on the current difficulty. On Easy, it does 7 (x3.5) damage; on Normal, it does 12 (x6) damage; on Hard, it does 18 (x9) damage.
