Settlements are small ruined structures in the End. They're the source of Dark Shulkers and Final Keys.
Settlements can be found in the same biomes End Cities can.
Settlements are made up of ruined pillars of Purpur and End Stone blocks.
There's a 50% chance that a Settlement will have a Trial Spawner in the middle. This Trial Spawner will spawn Dark Shulkers when a player comes within 10 blocks.
Mobs can spawn up to 6 blocks away from the Trial Spawner. 7 Dark Shulkers will spawn from it in total (+2 per extra player), but only 4 can exist at once (+2 per extra player). Every 2 seconds, it can spawn more mobs as required.
During an Ominous Trial here, a total of 9 mobs will spawn (+3 per extra player), and more mobs can exist at a time.
Trial Spawners in Settlements have a 25 minute cooldown before activating again.
Non-Ominous Trial Spawner:
1 Final Key
Ominous Trial Spawner (one of these is dropped):
1 Music Disc (Shulk) (see Custom Discs)
1 Music Disc (Tall) (see Custom Discs)
