User blog comment:The Black Easterling/How to make an Impregnable Fortress/@comment-26222246-20160104002200

I would make an inner wall out of utumno brick filled with my most precious resources and stuff I have and place my fortress at bedrock of the ocean at least 100km from the nearest shore. The entrance would be a ladder still in utumno brick leading to a door above the ocean so no mobs can get in. The floor will be mostly lava so that if someone goes in and uses a horn of summoning all the troops will burn. I will make a wall 10 blocks thick out of cobble around it with rangers 1.5 blocks deep in a trench and another trench in front with Galadhrim warriors but have pistons under their feet so I can make them charge into melee if needed. I would make the rest of the bridge after the two trenches covereing 5 blocks out of quagmire so it can't be jumped over. I will then install voltz and have 1000 laser turrets so no one can get within 64 blocks of my base without almost instant death.
