The Star Rail community is currently overwhelmed with wild rumors about patch 4.3. Players are talking about crazy self-damaging kits, surprise reruns, and special forms for fan favorite characters. HoYoverse did just drop official drip marketing for the next update, but a massive chunk of what you see on social media right now is completely made up.
| Topic | Status | Confirmed Details |
| New Character | Mortenax Blade | 5-Star Fire / Nihility. Focuses on debuffs/DoT, not HP-drain. |
| Fate Collab | Delayed | Part 2 is not in 4.3. Expect a later 2026 window. |
| Kafka / Acheron | Rumor | No “SP” or special forms confirmed for the v5.0 cycle. |
| Siren Rerun | Unconfirmed | No official confirmation of a Siren banner in the 4.3 cycle. |
| Sparkle Skin | Speculation | Currently no official assets or announcements for a new skin. |
If you are hoarding your hard earned Stellar Jades for a secret Acheron SP or the second part of the Fate crossover, you need to pause. Making pull plans based on community theories is a fast way to ruin your account. We went through the latest announcements to separate the real updates from the viral fiction. We will break down exactly what is confirmed for Mortenax Blade, what is happening with the Fate collaboration, and why those special form leaks are not real.
Mortenax Blade abandons Destruction for a new path
HoYoverse has officially revealed Mortenax Blade as the newest 5-star character arriving in Version 4.3. He is completely shifting away from his original identity. According to the Leaks, Mortenax Blade is now a Fire element character following the Path of Nihility.
Many YouTube channels are currently claiming his kit features a self-sacrificing “Infinite Fury” mechanic that drains his own health for massive damage. That information is heavily outdated and based on his old Destruction playstyle. As a Nihility unit, his actual gameplay will focus on applying strong debuffs and damage over time (DoT) effects rather than raw health scaling. If you already run characters like Black Swan or Jiaoqiu, Mortenax Blade is shaping up to be a strong addition to those team comps.
The Fate collaboration part two is delayed
Ever since the first phase of the Fate/stay night crossover event wrapped up, players have been waiting for Gilgamesh and Rin Tohsaka to show up. Recent rumors suggested part two was dropping in 4.3. That is entirely false.
Current reliable reports confirm that the second part of the Fate collaboration is not happening in the immediate update cycle. This is a strategic delay by HoYoverse to space out major crossover events, not a full cancellation. You can keep your crossover hopes alive, but do not skip strong 4.3 banners just because you think Saber’s friends are right around the corner.
Stop believing the Kafka and Acheron SP rumors
One of the biggest rumors circulating right now claims that both Kafka and Acheron are getting new SP forms in the version 5 update cycle, tied to a new lore location. Some players are even drafting up theory kits involving delayed detonations and instant execution mechanics.
There is absolutely zero confirmed data for any of this. These rumors stem from unverified community speculation and accounts with very mixed track records. HoYoverse has not teased or confirmed any special forms for Kafka or Acheron. Treat these claims as fun fan fiction rather than actual leaks.
What you should actually do with your Jades right now
If you need a strong Fire DoT or debuff unit, start preparing your account for Mortenax Blade. Gather your trace materials and keep an eye on official kit previews as we get closer to the patch launch.
For everything else, including rumored Sparkle skins or highly speculated rerun banners like Siren, keep your wallet closed. Only spend your jades based on confirmed livestream announcements. The gacha cycle is punishing enough without losing your savings to a fake leak.
