I am sorry m8. Bases close to world bosses mean just one thing, easy skeleton keys. I placed some golems out of my base, guarding my open map room, but that’s it, no other guardians outside my house anymore, even when i am not close to difficult mobs. If an old player returned to this game, it’s under the impression that any thrall can solo a world boss, so what happened to you had a “lesson” in the end for both of you. Keep the knowledge and move on.
