Since Terraria: Otherworld's cancellation I've been checking out what's coming in Terraria 1.3.6. Today, a new feature was teased that I had to come talk about: Block Replacement. If you're like me, you start building and then get the ability to get better stuff, so you tear down your build and start over. I rarely build anything permanent until near Hardmode, or at least post-Skeletron. This feature will let you replace blocks if you have a pickax equipped that is strong enough to mine the block you're replacing. You can even change out chests, and it will keep the contents. This could also help when you want some ore that happens to be holding in a lake...
