Honkai: Star Rail has a new build-guide focus in Mortenax Blade, and the kit sounds like the kind of character players will either build carefully or misunderstand spectacularly. GamingOnPhone frames Mortenax Blade as a 5-star Fire Nihility character who can work as a main DPS or support thanks to a dual-form mechanism. His kit revolves around HP consumption, debuffs, battlefield control, follow-up attacks and a Zone state that increases damage pressure while reducing enemy defensive value.
His Ultimate applies Balefire Bind, lowering enemy defence and increasing damage taken, before pushing him into Infinite Fury through his Zone system. That is exactly the type of character that needs a guide because raw damage numbers do not tell the whole story. Build him wrong and he becomes expensive drama. Build him well and he may become one of the stronger Nihility options in the game.
