Mortenax Blade Build in HSR (Honkai: Star Rail)

A new Honkai: Star Rail build guide recommends the best combat setup for Mortenax Blade.

Reforged in Hellfire is highlighted as the top Light Cone, with Divine-Querying Master Smith as the core relic set.

The guide also points to planar ornaments like Lushaka, the Sunken Seas, Sprightly Vonwacq, and Bone Collection's Serene Demesne.

Priority stats focus on crit rate, HP, and energy regeneration to improve damage and support utility.
