Last Cloudia: How to Reroll & Pick Best Units and Arks (v6.13.0)

Why Rerolling Matters in Last Cloudia v6.13.0

After burning a couple of evenings rerolling in Last Cloudia, I learned the hard way that this game isn’t just about strong units. Arks quietly decide how powerful your entire account becomes long-term. With the v6.13.0 meta (Edward Elric, Roy Mustang and the new Tensura units Hinata Sakaguchi and Benimaru) the gap between a “lucky” start and an “okay” start has never been bigger.

This guide is exactly what I wish I had when I started fresh for 6.13.0: a practical reroll workflow plus clear pull priorities that weigh Arks and units together, instead of treating Arks like an afterthought. If you follow it, you should be able to lock in a strong account in about 1-2 hours.

Your Reroll Goal: What a “Good” Start Looks Like

Before touching the reroll button loop, you need a clear target. What finally stopped me endlessly resetting was deciding on a concrete “good enough” account.

My v6.13.0 reroll benchmark:

• 2-3 S-tier units (at least one main DPS, one support/tank or healer)
• 1 top-tier Ark that has long-term, account-wide value
• Ideally at least one collab unit (Edward, Roy, Rimuru, Milim, Hinata or Benimaru) if those banners are up

If you hit all three, you are way ahead of the average fresh account. Even just 2 S-tier units plus a great Ark is worth keeping and building on.

Don’t make my first-timer mistake of chasing the “perfect” roll with 4+ S-tier units and multiple premium Arks. The odds are brutal; you’ll burn out rerolling instead of actually playing.

Step-by-Step Reroll Process (Mobile & Emulator)

I’ve rerolled both on phone and on an Android emulator. The process is simple once you get into a rhythm.

1. Start as a Guest

On first launch, always choose a guest account. Only bind your account (with Google, Apple, etc.) after you get a roll you want.

If you accidentally bind too early, you’ll have to switch to a different login or clear your app data more aggressively, which wastes time.

2. Blast Through the Tutorial Efficiently

The tutorial is unskippable in places, but you can speed it up:

• Turn on fast battle speed as soon as you can.
• Skip dialogue with tap/skip buttons whenever they appear.
• Auto-battle the early missions; you don’t need to play well here.

Once you unlock the first batch of free pulls and early crystals, you’ll hit the point where you can judge the account. On my setup (mid-range Android plus emulator) each loop took ~10-12 minutes once I got into a groove.

3. Spend All Early Crystals and Tickets

When the game gives you your first real freedom, claim everything in your inbox and missions, then go straight to the gacha screen.

• Use any collab tickets first (FMA or Tensura, depending on what’s active).
• Dump your free crystals into banners that can give both top units and valuable Arks.
• Avoid throwing pulls at obvious B-tier or outdated banners, no matter how cool the art looks.

Only judge the run after you’ve emptied all beginner tickets and welcome bundles. I almost rerolled away a Divine Beast Rei because I forgot I still had tickets to spend.

4. Reset Quickly If It’s Bad

If the pulls are underwhelming, reset:

• Android: Settings → Apps → Last Cloudia → Storage → Clear Data, then relaunch.
• iOS: Delete the app and reinstall (annoying, but reliable).
• Emulator (Bluestacks/LDPlayer/etc.): clone your instance with a clean base so you can swap accounts instead of reinstalling every time.

Once I set up a clean emulator instance and just rotated guest accounts, I could hit the 1–2 hour reroll window comfortably and still stay sane.

Pull Priorities – Units You Actually Want

Now, what are you actually aiming for in those pulls? Here’s how I prioritize units in v6.13.0 based on how much they’ve carried my runs.

Top DPS and Carry Units

You want at least one premium damage dealer that can brute-force story and events:

• Edward Elric (FMA collab) – Absurd all-round DPS. Great scaling, can delete mobs and bosses alike. If he shows up early, that’s an instant “consider keeping this” flag.
• Roy Mustang (FMA collab) – High burst magic damage and great for nuking waves. Slightly more setup-heavy than Ed, but ridiculously strong with the right skills.
• Divine Beast Rei – Non-collab beast of a DPS, stays relevant in almost all content. I’ve never regretted accounts that started with Rei.
• Blademaster Beyland – Consistent melee DPS, excellent long-term investment. Not as flashy as collabs but extremely solid.
• Goroth the Giant – This one’s controversial. Some lists underrate him, some put him in S-tier. In my runs, a well-built Goroth absolutely shreds early PvE and doubles as a chunky frontliner.

If your starting account has any two of those (or one of them plus another high-tier carry like V or Gen Asagiri), you’re in excellent shape.

Tanks and Frontliners

Tanks matter more once you hit harder bosses, but it’s still nice to start with one that stays useful:

Tanks and Frontliners

Tanks matter more once you hit harder bosses, but it’s still nice to start with one that stays useful:

• Advocate of God (Baran/Lougseus variants) – Strong defensive tools and utility, especially good paired with squishy glass-cannon DPS.
• Goroth the Giant again – fills both DPS and tank roles with the right build.

I don’t reroll for a tank specifically, but if I pull a meta tank plus a great DPS and Ark, that’s a keeper account.

Healers and Support

This is where v6.13.0 really shifted for me. Early on I tried to brute-force everything with DPS and potions, which worked… until it didn’t.

• Spirit Maiden Theria – Hands down the best healer right now. Massive sustain, safety in hard content, and future-proof. If she shows up in your first pulls, that’s a huge win.
• Rabbala – Great support with strong buffs; pairs well with any high-end DPS.
• Lukiel – Another solid healer/support option if you miss Theria.

I now treat “1 top DPS + 1 top healer/support” as just as good a start as “2 top DPS”. Spirit Maiden Theria has saved more of my runs than any extra damage dealer would have.

Collab All-Stars and New Tensura Units

Collab units are usually overtuned, and v6.13.0 is no exception:

• Edward Elric & Roy Mustang – Top of the meta; if the Fullmetal Alchemist banner is up, prioritize it.
• Rimuru Tempest & Milim – Still extremely strong carries if their Tensura banners return.
• Hinata Sakaguchi & Benimaru – The new Tensura arrivals in 6.13.0. Early impressions (and my limited testing on a side account) suggest they’re very strong, but their best Ark and team synergies are still being mapped out. If you love Tensura, it’s reasonable to aim for at least one of them plus a good Ark, then adjust once the community fully breaks them down.

Collab banners usually have a timer. If one you care about is live, that’s a strong reason to reroll now rather than later.

Why Arks Are As Important As Units

This is the part I completely underestimated on my first account. Units come and go with the meta, but Arks are permanent skill libraries that every future unit you pull can tap into.

Some Arks, like Arkh or Diablo, give access to skills and passives that massively boost damage, survivability or utility for any character once you unlock them. That’s why a reroll that lands a top Ark is often better than one that just gets an extra flashy DPS with no support.

Core Arks Worth Rerolling For

Exact Ark names and availability depend on current banners, but here’s how I evaluate them while rerolling:

• Does this Ark teach universally good skills? Things like generic damage boosts, crit rate, survivability passives, or strong utility (haste, casting speed, etc.) are huge.
• Is it tied to an active collab? Collab Arks often come with extremely powerful, unique skills that won’t be back for a long time.
• Is it future-proof? If an Ark boosts basic attack types or elements you’ll always use (like physical damage, human-type killers, etc.), it will keep paying dividends.

My personal rule: I’m happier with “2 S-tier units + 1 insane Ark” than with “3 S-tier units and no standout Ark”. The Ark can quietly make every future pull stronger.

When to Stop Rerolling (Realistic Checkpoints)

This is where most people (me included) fall into the reroll trap. Here are my sanity checkpoints:

• Checkpoint A (Good): 2 S-tier units (one DPS, one support/healer or off-tank). No standout Ark. You can safely keep this and rely on future banners.
• Checkpoint B (Great): 2 S-tier units + 1 strong, broadly useful Ark. This is my usual “stop rerolling” point.
• Checkpoint C (Jackpot): 3 high-tier units including at least one collab + 1 top Ark. Don’t reroll this, ever.

If you haven’t hit at least Checkpoint A after about 2 hours and several loops, consider accepting a slightly weaker roll; the time you save will more than make up for it as you actually play, farm and pull on later banners.

Dealing With Conflicting Tier Lists

When I started looking up “Last Cloudia tier list”, I got whiplash. Some sites rated Goroth as S-tier, others as A or even B. Older lists still had outdated units like Davan in top spots while completely ignoring the latest collabs.

Here’s how I handle that noise:

• Check the date. If a list isn’t updated for v6.13.0 or mentions none of the recent collab units, treat it as outdated.
• Look for cross-consensus picks. Names like Divine Beast Rei, Blademaster Beyland and Spirit Maiden Theria show up near the top across most recent lists and in actual player discussions.
• Use your own experience. If a unit feels strong in your runs and scales well with better skills/Arks, don’t stress if one random tier list rated them A instead of S.

Tier lists are a starting point, not gospel. For rerolling, just avoid obvious low-impact picks (like Phantom Thief Robin) and focus on the repeatedly praised names plus collabs.

Common Reroll Mistakes I Made (So You Don’t)

Here are the traps I fell into on my first serious reroll session:

• Ignoring Arks completely. I kept resetting accounts with great Arks because the units “didn’t look exciting enough”. Those accounts would have aged better than the one I kept.
• Chasing perfect collab combinations. Trying to get both Edward and Roy plus a top Ark wasted hours. I would have progressed faster sticking with just one of them plus a strong core Ark.
• Rerolling away Spirit Maiden Theria. I underestimated how important a top healer is. Don’t repeat that; she’s a massive quality-of-life boost.
• Spending pulls on bad banners. Early on, I threw crystals at every shiny banner. Now I only pull on banners that include either S-tier units or premium Arks.

If you avoid those, your reroll time will actually feel productive instead of like gambling in slow motion.

Final Thoughts – Lock In and Start Playing

Once you land an account with 2–3 strong units and at least one excellent Ark, commit to it. Bind it to your platform account, stop rerolling, and push story and events. Last Cloudia’s real fun starts when you’re building teams, experimenting with Ark skills, and taking on harder content-not when you’re stuck in an endless tutorial loop.

If I can leave you with one thing: treat Arks and units as a package. A slightly “worse” unit lineup with a god-tier Ark will often outperform a stacked unit roster with nothing to teach them. Reroll smart, not forever, and v6.13.0 will give you a foundation that carries you through future banners and balance shifts.
