In Crimson Desert, players can acquire the Electro-Mecha Longsword, a unique two-handed sword with Lightning Affinity, by defeating the Machina Knight at Marni's Outpost in northern Delesyia. This boss battle is divided into two phases, each requiring different strategies. In the first phase, the Machina Knight wields a longsword and performs three-hit combo attacks. Players should focus on timing their parries to counter these attacks and deliver damage during openings. Once the Machina Knight takes enough damage, he transitions to the second phase, switching to a spear, which increases his speed and aggression. During this phase, players should avoid attempting to block or parry spear attacks to conserve stamina and instead focus on dodging. The Machina Knight can also become invulnerable at times, launching seeking cubes that players must dodge. Successfully defeating the Machina Knight will reward players with the powerful Electro-Mecha Longsword.
