Mortenax Blade, revealed via the Honkai Star Rail 4.3 drip marketing campaign, is the only new character in the next patch. The rest of the banners are reserved for reruns. Mortenax Blade hails from the Fire element.

Unlike his counterpart, Blade, he treads on the Path of Nihility. The upcoming story will unveil how he unlocks the new power.

As specified, the Honkai Star Rail 4.3 banners will feature multiple rerun characters, along side Mortenax Blade:

First phase

5-star: Mortenax Blade and Yao Guang
4-star: Sampo, Luka, and Tingyun

Second Phase

5-star: Cyrene and Phainon
4-star: March 7th, Arlan, and Yukong

The corresponding Light Cone banner will feature the signature option of the 5-star characters. You can summon Mortenax Blade’s weapon, Reforged in Hellfire, during version 4.3.

New Trailblaze mission, maps, and enemies

A new Trailblaze mission titled “The Lethe Below the Living” will be available during patch 4.3. It will further the narrative of Planarcadia and explore Blade’s development after he absorbs Shuhu’s flesh in the latest chapter. His transformation into Mortenax Blade is potentially linked to the recent event.

The upcoming story quest will further unlock the Inkford Hermitage map and introduce new enemies. The special program has showcased two hostile entities: Murata Graphia, Founding Artist and God-Devourer Offspring.

New materials and Relic sets

Two new Relic sets are heading to the Honkai Star Rail 4.3 update. You can obtain them from the Path of Insight Cavern of Corrosion:

As Navigator Isee Sees It
Divine-Querying Master Smith

Additionally, HoYoverse will also introduce the following character development materials in the upcoming patch:

“Sneering Harlequin”
“Cosmic Sandpit” Series
“Omnicolor, Fool’s Own” Series
