Obsidian is a block created whenever water touches lava. When this occurs, the lava becomes obsidan. Obsidan can be crafted into an Obsidian Skull, which is an equippable accessory that provides protection from hot blocks, like Hellstone and Meterorite blocks, which would normally burn you. Obsidian is hard to find naturally due to water rarely spawning on lava, but the use of a bucket makes gathering obsidian less difficult.
