Today we introduce a new system to Trelm. You can now destroy obsidian using TNT and other explosive items, such as EnderCrystals and Creepers.
Each Obsidian block will have a value of 500 Health. The formula for damage is simple, 2 / distance. 1 damage per explosion. That's 500 TNT to destroy an obsidian block at a distance of 20.
Right click a block with a stick to view it's health.
