Quick Answer
The latest official Guildrun demo update in the collected material is Demo Update 0.5.6. It shifts development focus toward the full release, keeps the demo content mostly stable, and continues bug and balance monitoring. The update also changes Pollen's Sanctuary of Bloom, Zuri's The Cruel, and the second Red Rift reward flow.
Use this page as an update center, not a rumor feed. The official Steam Community update feed is the source of truth for exact numbers, while official store pages confirm the current demo context. Community pages can explain player impact, but they cannot replace the official version label or confirm an unlisted tooltip.
Current Version Check
The official 0.5.6 note is the current confirmed update reference. It says the team is shifting focus toward the full release, that demo content is mostly stable, and that bugs and balance will still be monitored. It also confirms the Pollen, Zuri, Rift Seal, and reward-visibility changes summarized below.
The official note also says that some in-game Stun descriptions had not yet been updated and were planned for a later hotfix. If a screenshot, video, or guide disagrees with the 0.5.5 rules, check its patch date before treating it as current.
Where to Check
Start with the official Steam Community update feed, then compare the Steam demo page and Leyline's official site. Competitor pages and Reddit threads can help identify what players care about, but official posts are safer for version numbers and change reasons. If a value is absent from the current official note, mark it To be confirmed.
The previous official video is Demo Update 0.5.4. Because “latest patch” is time-sensitive, recheck official sources before publishing a dated “latest” claim. If not rechecked, mark the live latest patch as not officially confirmed.
Latest Patch: Demo Update 0.5.6
Demo Update 0.5.6 is a smaller transition update rather than a broad system rework. The official note says the team is moving toward the full release, demo content is mostly stable, and bug or balance monitoring continues. That makes this the correct baseline for current character and item pages.
Hero and Red Rift changes
Pollen's Sanctuary of Bloom now scales Mana Regen at one point for every five Mana Regen instead of one point for every eight. This is a direct scaling change, so Pollen pages should describe the specialization as a stronger Mana Regen route without inventing a complete tooltip formula.
Zuri's The Cruel has base damage increased from 200 to 275. The official note also confirms that Rift Seal is automatically equipped from the second Red Rift run onward, removing one repeated manual step for that progression path.
Reward and bug-fix notes
Delayed relic and item rewards now show the event they came from. This is a quality-of-life improvement for checking reward provenance, not evidence that the reward pool or event odds changed. The remaining fixes are best treated as implementation corrections unless an official note connects them to a balance effect.
Exact details of every other bug fix, full-release balance change, and final-release system are To be confirmed unless they appear in the official 0.5.6 post.
Previous Major Update: Demo Update 0.5.5
The official overview frames 0.5.5 as a player-side buff patch with three jobs: make Endless stun-lock less oppressive, make rank-up and event choices less automatic, and fix bugs that were breaking intended builds.
Stun Resistance
Endless snake and mushroom tanks can attack fast enough to stun-lock heroes out of a fight. Stun resistance is a stacking player-only buff:
- Whenever a stun is actually applied to a hero, that hero gains a stun-resistance stack for 15 seconds.
- Each stack reduces later stun duration by 25%.
- Four stacks grant full stun immunity.
- Stun-immune heroes do not gain a stack.
- Stack durations are independent, similar to shields.
- Enemies do not gain stun resistance.
Yuuna, Skorn, Kai, Karsu, and Tilly are also stun-immune while casting their active abilities, which should make longer wind-ups more consistent.
Bug fixes
The official video highlights:
- Revive characters no longer lose active effects.
- Ratna's Fashionable specialization now accounts for all equipped items.
- Characters freeze less after teleport and resume attacking.
- Kai's The Bold is back to Stall 15 after an erroneous Stall 20 in the previous patch.
- Complex effect chains no longer stop midway; Assassin Elevation Prism should generate shards in all intended cases.
Class modifier buffs
Every change in this section is a buff. The stated goal is to make A and S rank-up decisions less obvious:
- Assassin: Poisonous Edge, Poisonous Eye, longer Lurker stealth, and a larger Enforced Presence Attack/Magic bonus.
- Duelist: five modifier buffs, including Poisonous and Burning Attacks plus double Rush duration on Critical Timing's crit bonus.
- Mage: Stalled Growth, Stalled Heat, better Burning Absorption scaling, and a larger Magical Growth Magic bonus.
- Mystic: Shield Formation now has 400 base shielding; Stall Enlightenment mana regen is doubled.
- Vanguard: Burning Eye starts at 30 Burn; Burning Aura scales better with HP and has a higher max Burn; Tank Poisonous Aura is buffed; The Best Offense scales better with Defense; Second Wind has a shorter Stall duration.
- Warrior: Ranger now also gives 50 Attack with +1 range; Scaling Attack and Victorious Presence get larger Attack bonuses.
Relics and items
The video says 32 relics and items changed: 29 buffs for underperformers and 3 nerfs for outliers, with a focus on event offerings.
- Rare relics with quest requirements are easier to complete, including Burn, Violence, Poison, and Arcane Conduit.
- Debuff and buff amounts increase on several pieces, including Poison and Burn Bobble, Hasty and Searing Vest, Toxic Shiv and Gauntlet, and Searing Tome.
- Duelist Outbreak Banner is redesigned because it was the week's largest win-rate outlier. Instead of the old effect, a Duelist auto attack now deals 15 bonus damage per debuff type on the target.
Hero balance
The stated goal is to make B-rank specialization picks more interesting:
- Karsu's Warband now gives 4 Attack Speed per cast instead of 3. Her 0.5.4 mini-rework is left in place.
- Hoyoung's Conduit spec gets more mana regen.
- Zuri's The Cruel gets 10 more starting mana.
- Nyx's The Wild gets higher Attack, Magic, and Attack Speed scaling.
- Reyna's Boxer loses some base damage for more scaling. It becomes stronger than before once Reyna reaches 135 Attack.
- Funke's Wildfire loses its base Burn amount but gains Magic Burn scaling. The new numbers overtake the old Burn around 130 Magic, which the video says is below typical Endless Funke Magic.
- Niklas's Hoarder now adds Rush 15. The Dealer now creates an item every four casts instead of 25% of the time, with higher base damage.
- Skorn's The Haughty gets 100 base Shield per rank, so it feels less dead before Stall triggers stack up.
The weekly Discord challenge mentioned in the 0.5.5 video is the Master Mystic Challenge: clear Double or Triple S using only Mystics.
Previous Patch: Demo Update 0.5.4
0.5.4 focused on hero excitement and specialization variety, including a Karsu mini-rework. Quality-of-life notes include hiding item slots over health bars while dragging other characters, cleaning resurrection VFX, Ming's Enlighten scaling correctly on rank-up, Sentinel's Plate giving 40 bonus Defense instead of 60, and Niklas no longer starting with Quantity Over Quality in Red Rift.
Endless stun stacking was already identified as a problem, but the video says the real stun-duration solution was not ready yet. That solution arrived in 0.5.5 as stun resistance.
0.5.4 also added a Red Rift-only band-aid: the Act 2 boss resists Frost by 50%, so four Frost are needed to reduce Defense and Attack Speed by one instead of two. The Red Rift leaderboard now resets weekly with each patch. Broader Frost and poison system changes are described as full-release work, not demo work.
Other 0.5.4 highlights:
- Most second-event ring items gained extra stats; Greedy Ring did not. Power crystals and two shard-generation items were toned down.
- Karsu's Snowpiercer fires extra arrows for every 50 Attack Speed, up to 14 arrows. Arrows apply 3 Frost plus 2 per rank. Falling Snow no longer fires five extra arrows; it now reduces next-cast mana from auto attacks, down to a 40 mana minimum.
- Kai received base-stat and active-damage buffs, with a slight Intrepid Rush-duration nerf.
- Logan's The Iron now grants an extra item slot.
- Grace's Salvation shield duration increased, Benevolent Stall time was reduced, and Selfless backup shields were lowered.
- Niklas's passive now gains 50% of consumed-item stats at base plus 25% per rank, up to 125% at S rank, instead of 100% immediately.
- Rowan Tectonic was slightly nerfed. Ming got a follow-up scaling buff. Gustav Blizzard gained more Act 1 damage and Frost per tick. Fiona Lustrous now inflicts Burn when a shielded hero is damaged. Skorn received a band-aid base-stat and passive buff for Act 1.
Important Patch History
Patch 0.5.3 from August 4, 2026 remains important because many current hero pages still use it as research context. That patch buffed Zuri's The Cruel, raised Dragomir's active Magic scaling from 200% to 250%, adjusted Sanguine positioning, and connected Kai to Shield/Stall changes.
Patch 0.5.1.718 from July 23, 2026 is the first public demo balance patch in the dedicated patch-notes material. High-level changes include hero and specialization tuning, relic and modifier changes, Endless and Red Rift adjustments, Challenge Fight changes, bug fixes, quality-of-life improvements, and leaderboard/reset improvements.
Patch 0.4.30 changed Endless scaling and identified top-performing deep-Endless builds. Patch 0.4.30.645 followed up after the developers reviewed data and found that some fight types and builds still needed adjustment. Version 0.4.26 renamed the game to Guildrun, so older material may still use the previous name.
What Changes Usually Affect Guides
Hero changes affect tier lists, builds, and character pages. Class modifier changes affect Rush, Stall, Crit, Attack, Magic, Poison, Frost, Burn, Shield, and sustain. Relic and item changes can make a build stronger or weaker even when the hero itself did not change.
Difficulty and enemy changes affect Red Rift, SS, SSS, and Endless pages. Bug fixes also matter because an old meta build may have depended on unintended behavior. 0.5.5 examples include revive effects, Ratna Fashionable item accounting, teleport freeze, Kai Stall values, and Elevation Prism shard generation.
Why Old Guildrun Builds Stop Working
Old builds can stop working because the hero changed, the specialization changed, or a relic/item that supported the build changed. They can also stop working because a class modifier changed, a Rush or Stall mechanic was fixed, stun behavior changed, enemy scaling moved, or a bug was removed.
After 0.5.5, treat old Endless stun-lock advice, old Outbreak Banner Duelist plans, old Funke early-Burn numbers, old Kai Stall 20 claims, and old 0.5.3-only Zuri or Dragomir rankings as stale until rechecked.
How Often Is Guildrun Updated?
The material says Guildrun received weekly balance patches during closed Alpha, and the public demo continued with a balance update one week after launch. Official 0.5.4 and 0.5.5 videos also present a weekly demo cadence. Phrase that as observed cadence, not a permanent guaranteed schedule. Future update frequency is 待确认.
Because updates are frequent, every important guide should include either a patch label or a freshness warning. This is especially important for tier lists, builds, character pages, Red Rift, Endless, Floor 50, and SS difficulty.
How This Site Should Update Pages
When a hero changes, update the hero page, tier list, builds page, and any mode page that depends on that hero. When a relic or item changes, update relics, builds, Endless, and affected character pages. When stun, Frost, or enemy scaling changes, update Endless, Floor 50, Red Rift, and SS difficulty first.
Keep patch history factual and compact: version, source, changed system, and affected guide pages. Use the official video for the current overview, then send players to Steam or Leyline notes for the full list.
Localization Notes
The patch material mentions localization/text fixes and localization preparation. It does not prove complete Japanese localization. Any Japanese localization page should therefore say 待确认 unless official sources confirm the language list.
