Dagger made of dark, polished obsidian, used in sacrificial rituals. Killing innocent being in a single swing can cause ore to generate Breaks after a successful hit.
The Obsidian Dagger is a HardmodeBroadsword which is very weak when used as a traditional weapon but when used to kill a Critter, it will cause the same effects as smashing a Demon Altar would, destroying the dagger in the process.
