New Trailblaze Mission Expands the Planarcadia Story
Version 4.3 continues the Planarcadia storyline with a permanent Trailblaze Mission called “The Lethe Below the Living.” Players travel toward the mysterious Lethe River while uncovering forgotten memories and witnessing the final journeys of souls connected to the World in Canvas.
The mission becomes permanently available after the update. Players must complete “Planarcadia – So Laughed the Masses” before starting it. Those who have not reached the required story chapter can still experience it early through the Finality’s Vision feature.
Mortenax Blade Becomes the New 5-Star Character
The biggest addition in Version 4.3 is Mortenax Blade, a 5-star Fire character following the Path of Nihility.
Unlike traditional Nihility characters that focus mainly on debuffs, Mortenax Blade introduces a unique combat style through a special Zone mechanic. While this Zone is active, teammates help reduce enemy DEF and increase Vulnerability, allowing Blade to trigger additional follow-up attacks.
His gameplay rewards team coordination rather than individual damage, making him an attractive option for players who enjoy strategic combat.
Alongside the character, HoYoverse also releases his signature 5-star Light Cone, Reforged in Hellfire, through the limited Light Cone Warp.
Inkford Hermitage Opens as a New Area
Players can explore Inkford Hermitage as the newest location in the World in Canvas.
The area represents the boundary between reality and the painted world, serving as the final resting place for imagenae after they complete their journeys. Besides expanding the game’s lore, Inkford Hermitage introduces new exploration opportunities and becomes part of the Version 4.3 story progression.
Version 4.3 Events Offer Valuable Rewards
Several limited-time events help players earn useful rewards throughout the update.
The largest event is Pixel Plane Rumble, where players customize aircraft and battle through arcade-style aerial combat. Another event, Wispae Amusement Park, focuses on designing attractions inside the World in Canvas.
Players who successfully obtain Mortenax Blade can also unlock the exclusive Trailblazer Back Outfit “Karmic Fire of the Distant Shore” through the Gift of Tempered Blade event.
Meanwhile, Gift of Odyssey returns with one of the most valuable login campaigns, allowing players to claim 10 Star Rail Special Passes after seven days of logins.

New Gameplay Features Improve Endgame Content
Version 4.3 upgrades several endgame modes while introducing a brand-new challenge system.
The biggest addition is Starward Mode, which expands Treasures Lightward. Instead of forming one or two teams, players now create three separate teams to clear three different stages. Completing these challenges rewards additional Stellar Jades and other valuable items.
The update also refreshes:
Apocalyptic Shadow
Pure Fiction
Memory of Chaos
Anomaly Arbitration
Each mode includes new enemy effects and seasonal combat bonuses to encourage different team compositions.
System Improvements Make Daily Play Easier
Version 4.3 introduces several quality-of-life improvements that reduce repetitive tasks.
One of the most useful additions is a new Daily Training mission that lets players quickly complete activity requirements by spending a Fuel Voucher or a Deep Immersifier.
Other improvements include:
Cross-device settings synchronization
Language Resource Management
Reduced update download sizes
Mobile Home Screen widgets
Warp history extended from six months to 12 months
Additional achievements, messages, and collectibles
These updates make account management much smoother across multiple devices.
Audio and Performance Receive Major Updates
HoYoverse also improves localization and overall game performance.
English, Japanese, and Korean voice lines receive updates across multiple Trailblaze Missions and characters. The update also includes visual improvements, interface refinements, combat optimizations, and numerous bug fixes affecting character abilities, gameplay systems, and event modes.
Rather than introducing sweeping gameplay changes, these improvements help create a more polished experience throughout Version 4.3.
