Honkai: Star Rail 4.3 dropped the continuation of the Planarcadia arc on June 1 for most servers, pushing players deeper into the World in Canvas with Mortenax Blade as the new 5-star Fire Nihility swordsman. The story splits focus between the Trailblazer heading to Inkford Hermitage to warn Graphia and Blade himself using Voracity power to cut out Shuhu and break his curse.

Blade's kit revolves around an Ultimate that drops a Bounded Field called Fornax Ex Corpore, inflicting Balefire Bind on enemies for DEF shred and vulnerability while he enters Infinite Fury for boosted crits and a second stronger Ultimate. Teammates attacking under his field build charge for his HP-draining skill that bounces Fire damage, with the whole thing scaling off his Max HP for that classic self-damage whale bait.

Reruns of Yao Guang then Cyrene and Phainon fill the banners, a free Trailblazer outfit drops via the Gift of Tempered Blade event after pulling Blade, and new modes like Starward plus a customizable Wispae Amusement Park in the canvas world round out the package. A Fate/Stay Night collab is already teased for later this summer with free Gilgamesh or Archer logins. Whales are already logging in to test if the HP scaling actually moves the needle or just drains their Stellar Jades faster.
