Where it spawns
Built by a player: four soul sand or soul soil blocks in a T, with three wither skeleton skulls on top.
How it thinks
Each moment it runs the most important goals it can (lowest number first); a more important goal interrupts a less important one. Read from the game's code and put in our own words.
What it does
- 0Stays still while charging up after being spawned.
- 2Keeps its distance and shoots at its target.
- 5Flies around at random, keeping out of water.
- 6Looks at a nearby player.
- 7Looks around at random.
Who it goes after
- 1Fights back against whatever hurt it.
- 2Picks the nearest creature it can see as a target.
From our testing:
- The Wither does not use the "aggressive" state; each of its three heads picks its own target.
How Emma beats it
She stays away from it. Our plan is a trap: summon it with its head inside bedrock.
- The Wither has three heads that each pick a target. She treats it as after her whenever one of them is aimed at her.
- In the open it is the one mob she always avoids and never hunts.
- Trapped with its head in bedrock, it suffocates on its own in about 5 minutes. She doesn't build that trap herself yet.
Lab result: Trapped: 3 of 3 kills with no damage. In the open: 3 of 3 deaths in about 14 seconds.
From Emma's own fighting code and our combat lab (Hard difficulty). All the hard fights
