Quick Guide
  • Guildrun AI core loop revolves around managing shards to rank up heroes from C-Rank to S-Rank.
  • Yuna is the premier DPS choice, specializing in a devastating Poison-Crit synergy.
  • Shard management is critical; freezing the shop for high-value relics like the Assassin's Hood is a pro strategy.
  • Poison Stacking scales exponentially in the late game, allowing for millions of damage in Endless Mode.
  • Tank Positioning is vital for surviving Act 2 bosses like the Frost Dragon.

Getting Started with Guildrun AI Progression

The journey in Guildrun AI begins with a single choice: your starting hero. Whether you select Sal, Hoyoung, or Yuna, your primary objective is to navigate the rift, collect shards, and build a team capable of handling increasingly "broken" encounters. The game rewards aggressive scaling and calculated risks in the shop.

Video Highlights:

  • Demonstrating the power of a Rank S Yuna in the late game.
  • How to effectively use the Shop Reroll mechanic to find specific hero shards.
  • Strategy for defeating the Hydra and Frost Dragon bosses.
  • Breakdown of the Endless Mode scoring and damage potential.

To succeed, players must understand that Guildrun AI is not just about raw power but about the synergy between hero classes and the relics you acquire. Shards are your most valuable resource, used for hiring new heroes, buying items, or ranking up your existing roster. Ranking up a hero doesn't just increase stats; it unlocks transformative abilities that can define your entire run.

Economy Tip

Early in the game, prioritize the Shard Starter Kit or relics that increase shard gain per surviving hero. This sets up a massive economic advantage for Act 2 and beyond.

Hero Tier List and Class Synergy

In the current Guildrun AI meta, heroes are categorized by their utility and scaling potential. While any hero can be viable with the right relics, certain characters like Yuna offer a higher ceiling for damage output due to their innate class bonuses.

Yuna (Assassin)

  • Primary Stat: Crit / Poison
  • Best Role: Main DPS
  • Key Ability: Shuriken Shadow Strike

Pollen (Mystic)

  • Primary Stat: Magic / Debuff
  • Best Role: Support / Healer
  • Key Ability: Flower Field Poison

Yuria (Tank)

  • Primary Stat: Defense / HP
  • Best Role: Frontline
  • Key Ability: Petrifying Stun

Building a balanced team is essential. A common mistake is focusing entirely on DPS, leaving your backline vulnerable to flanking enemies or AOE attacks from bosses. A sturdy Vanguard like Jury or Yuria ensures your Assassins have the time they need to stack poison and trigger critical hits.

Positioning Warning

Always check the enemy's movement patterns. If an enemy has a "Jump to Backline" ability, place your tank slightly further back to intercept them before they reach your squishy Mystics.

The Ultimate Poison-Crit Build Guide

The most "broken" build currently available in Guildrun AI is the Poison-Crit Assassin setup. This build relies on the interaction where critical hits inflict poison, and poison enemies take increased damage from critical strikes.

1

Secure Yuna Early

Pick Yuna as your starter or find her in the first shop. Her Shuriken Shadow Strike is the foundation of this build.

2

Focus on Rank A Upgrade

Reach Rank A as quickly as possible to unlock Stealth on Kill. This keeps Yuna untargetable while she shreds the backline.

3

Stack Poison Relics

Look for the Poison Ascendancy relic. This causes enemies to lose a percentage of max HP whenever they take poison damage.

4

Reach Rank S Mastery

At Rank S, Yuna gains massive Omni-Vamp and guaranteed crits. This allows her to solo most encounters if the rest of the guild falls.

This build scales into the millions of damage points because poison ignores traditional armor values. When combined with Pollen's debuff amplification, the stacks can reach over 500 on a single target, melting even the toughest Act 2 bosses in seconds.

Crit ChanceHighItems / RelicsTriggers poison application
Poison StacksHighPollen / Rank-upsMassive DOT and max HP shred

Attack SpeedMediumQuiver ItemFaster stack application
Build Synergy

Pairing Yuna with a Rank A Pollen is the "secret sauce." Pollen's ability to increase the amount of each debuff on enemies by 100% effectively doubles Yuna's damage output instantly.

Itemization and Relic Strategy

Items in Guildrun AI provide the raw stats needed to survive, while Relics provide the game-changing mechanics. Understanding which items to sell and which to keep is the hallmark of an expert player.

Big VestItemTanksMassive HP boost for Act 2
Assassin's HoodItemYuna / SalEssential for crit-based scaling
Harmony CrystalRelicAllIncreases team size to 4 heroes
Poison PrismRelicAllCrit chance scales with bank shards
Flask of ManaItemMysticsEnsures early Flower Field uptime

Guildrun AI also features a "Quest" system for items. Some items, like the Shield Accumulator, require you to survive a certain number of combats to unlock their full potential. Always prioritize completing these quests early in an Act when enemies are weaker.

Must-Have Relics for 2026 Runs:

  • Poison Ascendancy for HP-based shredding
  • Assassin's Greed for permanent attack scaling
  • Frontline Barricader for increased tank size
  • Shard Precision Prism for late-game crit capping
  • Stall Hourglass for base stat boosts
Item Management

Don't be afraid to sell low-tier items like the Aegis to afford a high-tier Rank upgrade. A Rank A hero is almost always better than a Rank C hero with full items.

Conquering Act Bosses and Endless Mode

The Act 1 Hydra and Act 2 Frost Dragon are the primary gear checks in Guildrun AI. The Hydra requires high AOE damage to manage multiple heads, while the Frost Dragon requires careful positioning to avoid its freezing breath which hits adjacent heroes.

BossMain ThreatCounter Strategy
HydraMultiple attacksHigh poison stacks on the main body
Frost DragonFrost breath (AOE)Spread heroes out; use Yuria to taunt
Endless MobsHigh HP scalingRely on Poison Prism and % HP damage

Once you defeat the Frost Dragon, you enter Endless Mode. Here, the difficulty spikes exponentially. The key to ranking high on the global leaderboard is the Shard Precision Prism. By hoarding shards instead of spending them, you can push your hero's crit chance to over 700%, resulting in multiple shurikens or attacks per action.

1

Boss Preparation

Before the Frost Dragon, ensure your Tank has at least 1,500 HP and your DPS has Omni-Vamp.

2

The Spread Formation

Position your tank on one side and your DPS on the other. Never group heroes together against dragons.

3

Endless Scaling

Stop spending shards once your core team is Rank S. Let the shards accumulate to boost your relics.

Endless Secret

In the late stages of Endless Mode, damage numbers can reach 1.4 million per hit. At this point, defense is less important than "on-hit" healing and stealth mechanics.

Guildrun AI Frequently Asked Questions

Q: How do I unlock Rank S heroes in Guildrun AI?

Rank S is achieved by collecting multiple duplicates of the same hero in the shop or using rare Rank-up tokens found at campfires. Rank S unlocks a third item slot and a powerful mastery passive.

Q: What is the best way to farm shards?

Prioritize 'Challenging Encounters' early on. While they have 150% increased stats, they offer significantly higher shard rewards and epic relics that accelerate your progression.

Q: Can I combine duplicate relics?

Currently, duplicate relics do not combine. However, having two of the same relic (if allowed by the shop) will stack their effects, which is incredibly potent for poison or crit builds.

Q: Why did my hero die instantly in Endless Mode?

In Endless Mode, enemies eventually gain enough damage to one-shot heroes. You must rely on Stealth (Yuna), Petrification (Yuria), or massive healing (Pollen) to survive past the initial waves.

Final Verdict

The Guildrun AI meta favors those who can balance a greedy economy with a specialized team build. Focus on Yuna, master the poison mechanics, and watch your damage numbers soar into the millions.
