Seed: -594987688368855 (Spawn Point should be around 68 67 146)
Note: I did not originally find this seed. Someone else found this seed. I found this seed on https://www.gameskinny.com/necv7/top-10-minecraft-seeds-for-the-112-update/5. However, I did find more locations on the world.
End Portal Rooms (Stronghold)
Cave Spider Spawners (A lot of them)
Here's the Amidst map of "-594987688368855".
