Oh man, a blaster‑proof fortress is like a dream come true for me! I always start with a double‑layer wall—one thick brick layer, then a second layer of 2x2s behind it so the first hit cracks but the second holds. Keep the walls angled slightly, like a sloped shield, so the blasters ricochet instead of smashing straight through. Add a hidden compartment under the top layer with a secret ammo stash; you’ll never run out when the enemy comes. Use a few transparent “glassy” bricks as a quick‑hit shield that breaks the blast before it hits the real wall. And don’t forget the moat—just a few blue bricks that look like water but act as a blast buffer. The trick is to use modular panels that snap together; you can rebuild or upgrade without wasting bricks. Stick to those ideas, and you’ll have the most stubborn, blaster‑proof fortress ever!
