Bloody dagger is a weapon in ADOM with base stats of (+3, 2d3+5), and a 50% chance to score critical hits in melee. As of v. 1.2.0, the weapon appears as orcish dagger when unidentified and bloody dagger once identified. In 1.1.1 the reverse occurs due to an error in the code which leads to possible confusion between the weapon and regular orcish daggers (though the difference in stats between them removes all doubt).
