In Honkai Star Rail 4.3, players can now obtain Mortenax Blade's signature light cone, Reforged in Hellfire, through the gacha banner. This 5-star item is tailored for Mortenax Blade, providing significant boosts to his performance. At superimposition level 1, it increases the wearer's Max HP by 30% and allows them to regenerate 20 Energy at the start of their turn, which can trigger once per wave. Additionally, when the wearer uses a Skill Attack, the target is inflicted with the 'Purgatory' state for two turns, increasing the CRIT DMG they take by 30%. Given Mortenax Blade's unique abilities, the light cone is crucial for maximizing his damage output and debuffing enemies. If players do not acquire Reforged in Hellfire, they may find themselves needing to adapt Mortenax Blade's build, which could be restrictive. Although the light cone can be used by other Nihility characters, it is best suited for Mortenax Blade, making it a worthwhile investment for those pulling for him.
