Anime GuardiansSteel Ball Run Quest Units Guide

The newest Anime Guardians update has added a full Steel Ball Run themed event with new quest units, exclusive artifacts, special currencies, and multiple game modes to grind. A lot of players are confused about where to start because the update throws several quests and farming stages at you immediately.

The good news is that the event is actually pretty straightforward once you understand how each part connects together. Most of the grind revolves around farming Desert Grandline, collecting Green Spins, gathering body parts, and running the older UA Flag event efficiently.

This guide will explain everything step-by-step in simple terms, including how to complete both Diego and Valentine quests, the fastest farming strategy, the best units to use, and how to get all three new artifacts as quickly as possible.

Anime GuardiansSteel Ball Run Quest Units and Artifacts Guide

The update mainly focuses on:

  • Diego Brando quests
  • Valentine quests
  • Green Spin currency
  • Desert Grandline farming
  • UA Flag farming
  • New artifacts
  • New event game modes

Most of the progression is tied together, which means you will naturally unlock multiple rewards while farming the same stages repeatedly.

How To Start the Questlines

When you enter the event area, you will see both:

  • Valentine
  • Diego

Speak to both NPCs immediately.

Valentine Quest

Valentine only has one quest option. Simply press:

  • Yes

Diego Quest

Diego has two quest prompts instead of one. Make sure you accept both quests before leaving.

A lot of players accidentally skip one of Diego’s quest options and later wonder why their progress is not tracking properly.

Valentine Quest Requirements

To complete Valentine’s full questline, you need to:

1. Earn 100,000 Green Spins

These are obtained from:

Desert Grandline

Green Spins are the green coin currency shown after each clear.

2. Clear Desert Grandline 35 Times

This part is easy because you will naturally complete it while farming the Green Spins.

3. Collect 100 UA Flags

UA Flags come from a completely different game mode which is explained later in this guide.

Diego Quest Requirements

Diego’s questline is slightly longer.

You need to:

1. Earn 50,000 Green Spins

Again, these come from:

Desert Grandline

2. Collect Body Parts

You need:

  • 3 Arms
  • 2 Legs
  • 2 Eyes

These all drop from the event stages.

3. Evolve Diego

After unlocking Diego Brando, you still need to evolve him.

To evolve Diego, you need:

  • Diego’s Time Clock
  • 3 Hearts

The Time Clock is obtained by clearing:

Desert Grandline 25 Times

The Hearts also come from the event stages.

Best Team For Desert Grandline

Desert Grandline is not extremely difficult if you already own strong meta units.

Some of the best choices include:

  • Gyro
  • Hutaos
  • Chain
  • Sun Jing Wei

These units clear waves very quickly and make the farming process much smoother.

You should also bring:

  • Blast
  • Subaru

This combo is still incredibly strong for fast farming.

Fastest Desert Grandline Farming Strategy

Once the stage begins:

  1. Enable Super Fast Waves
  2. Set up near the front
  3. Place Blast units first
  4. Place Subaru
  5. Add your DPS units around them
  6. Let the run finish automatically

With a strong team, runs usually take around:

2 Minutes

Each clear guarantees:

  • 2,000 Green Spins

Since you need to clear the stage dozens of times anyway, you will naturally gather most required drops over time.

How To Get UA Flags Fast

UA Flags are required for Valentine’s quest and are farmed in an older event mode.

To access it:

  1. Go near the summon area
  2. Turn toward the Advanced section
  3. Find the Green Star NPC

This opens the older event stage containing:

  • UA Flags
  • Older crafting materials
  • Previous event rewards

Best UA Flag Farming Method

The most important thing here is:

Play On 1000% Difficulty

Even though the lobby only visually shows 5 flags, the mode actually gives:

10 Flags Per Run

This is extremely important because it cuts the grind in half.

Since you need:

100 UA Flags

You only need:

10 Runs

instead of 20.

Best Units For UA Flag Farming

This stage has:

  • Two paths
  • Large map size
  • Long wave count

Because of this, fully AoE units perform best.

Recommended units:

  • Johnny
  • Gyro
  • Chain
  • Robin
  • Subaru
  • Blast

Robin vs Subaru

A lot of players wonder which support is better here.

Robin

Robin is easier to use because:

  • She upgrades everyone automatically
  • Less repositioning required
  • Better for lazy farming

Subaru

Subaru still works great but requires:

  • Replacing positions
  • Moving support coverage
  • More setup management

If you own Robin, she is generally more comfortable for this mode.

UA Flag Stage Setup

Once inside:

  1. Activate Super Fast Waves
  2. Stand where both paths are visible
  3. Mirror your unit placement on both lanes
  4. Place Blast units first
  5. Add AoE DPS units
  6. Use support units after setup

The stage has:

100 Waves

so it takes significantly longer than Desert Grandline.

Average run time is roughly:

10 Minutes

New Artifact Farming Guide

The newest game mode also drops:

  • New artifacts
  • Additional rewards
  • Event progression items

For this mode, fully AoE units become even stronger because enemies approach from multiple directions.

Best Team For Artifact Farming

The strongest setup shown used:

  • Johnny
  • Gyro
  • Chain
  • Alan Joestar
  • Blast
  • Subaru

This setup works extremely well because nearly every important unit has:

  • Huge AoE coverage
  • Fast wave clear
  • Strong DPS scaling

Best Artifact Combination

The guide specifically highlights:

Full AoE Artifact

This artifact converts units into:

Full AoE Attackers

That effect is incredibly powerful in multi-lane stages.

For support units:

Blast

Use:

  • Claymore Scepter

Subaru

Use:

  • Abyssal Frost Aegis

This setup improves:

  • Economy
  • Upgrading
  • Overall farming speed

The Steel Ball Run update in Anime Guardians adds a surprisingly fun grind with multiple connected systems. While the event looks complicated at first, most of the progression naturally overlaps once you start farming Desert Grandline regularly.

The biggest grind by far is definitely the UA Flags because of the 100-wave stage, but using the 1000% difficulty trick makes it much more manageable.

If you focus on strong AoE units like Gyro, Johnny, and Chain while using Blast and Subaru for support, you should be able to clear every new event mode very comfortably and unlock all the new units, evolutions, and artifacts without too much trouble.
