Command an Army Mongols Update Guide: 7 New Units

Update 3 has landed in Command an Army, and it's the biggest content drop the Roblox strategy game has seen so far. Whether you're chasing the first five-star unit in the game or just trying to figure out where your Skill Crystals should go, this Command an Army Mongols update guide breaks down every new unit, evolution, code, and system so you don't waste Gems on day one.

The Mongol update (officially logged as Update 3) adds a free Battle Pass with three Mongol units, two banner units, two evolution paths, and three brand-new systems: the Skill Tree, Auto Delete, and the AFK Server. There's a lot to unpack, so let's go through it in the order you should actually tackle it.

What's New in the Mongol Update (Update 3)

According to the official patch notes posted in the Command an Army Discord on October 3, 2026, Update 3 includes:

• Mongol Battle Pass (Season 1) — a free, 50-tier pass with quest-based progression
• Seven new units — three from the Battle Pass, two from summoning, two from evolutions
• Laestrygonian — the game's first-ever five-star unit
• Two new evolutions — Mace → Morningstar and Pikeman → Phalangite
• Skill Tree — a per-unit progression system using Skill Crystals
• Auto Delete — automatic inventory cleanup while farming
• AFK Server — passive progression while you're away
• Four new codes — free Gems and Skill Crystals

The update is live now on the official Roblox page, and the Battle Pass is labeled "Season 1," which strongly suggests future seasons are planned.

All 7 New Units in the Mongol Update

The headline number is seven new units, but they come from three completely different systems. Here's the full breakdown:

Notice that you can't get everything from one place. Three units come from the Battle Pass, two come from summoning, and two come from evolving units you may already own. If you want a complete collection, you'll need to work through every part of the update.

One naming note: community sources spell some of these units differently (Korchin/Khorchin, Batar/Bataar, Lragonian/Laestrygonian). The Discord patch notes use Nökör, Bataar, Khorchin, and Laestrygonian, so those are the spellings to trust.

Laestrygonian: The First 5-Star Unit

This is the marquee addition. Laestrygonian is the first five-star unit in Command an Army history, and the summon banner lists it at a brutal 0.01% pull rate. For context, that's roughly 1 in 10,000 pulls without pity or luck boosts.

A Super Luck event is running alongside the banner, and there's a Super Luck potion in the Battle Pass rewards that players speculate is meant for rolling skills or units. Even with boosts, expect Laestrygonian to be a long-term chase rather than a day-one unlock. Community testers who pulled it describe it as clearly stronger than every existing unit in head-to-head comparisons — but treat that as early player experience, not settled fact.

Myrmidon: The 4-Star Frontline

Myrmidon is the more realistic banner target at four stars. It's a heavily armored frontline unit that deploys in shield formations, and testers report it holds up well in extended fights. One content creator compared a level 1 Myrmidon against a level 17 Spartan and noted the level gap matters enormously — so don't judge Myrmidon until you've invested levels into it.

Reported Myrmidon-style stats from community testing include roughly:

Formation options include arrow, U-shaped, and straight-line arrangements, which changes how the unit spreads across the battlefield. Myrmidon has no evolution path as of Update 3.

Battle Pass Units: Nökör, Bataar, and Khorchin

The Mongol Battle Pass is free — no premium purchase required. Instead of earning XP automatically, each of the 50 tiers is tied to a specific quest you must complete. That means finishing the pass takes real time, and the quests are reportedly on the grindy side.

Reward tiers for the three Mongol units:

Khorchin is the standout — a mounted four-star unit that players are already calling the best free reward in the update. The pass also hands out duplicates of featured units, which helps you ascend them further without spending Gems.

New Evolutions: Mace and Pikeman

Two older units just became relevant again. Before you clear out your inventory, check whether you own these:

Mace's evolution into Morningstar gives it a completely different look and a much higher rarity tier. Pikeman's Phalangite form adds a shield, giving it extra defensive utility in certain team setups. One caveat from player testing: some displayed stats can look odd after evolution, so check the full unit details rather than assuming every number goes up.

The bigger lesson here is that evolution paths make old units worth hoarding. If you already own Mace or Pikeman, you're partway to a new unit for free.

Skill Tree, Auto Delete, and AFK Server Explained

These three systems are the real long-term changes in the Mongol update, and two of them are easy to overlook.

Skill Tree (and the 5,000 Gem Reset Trap)

The Skill Tree is a per-unit progression system with upgrade nodes. Instead of only collecting units, you now invest resources into individual units for permanent bonuses. Some bonuses that players previously expected to be trait-style mechanics are now tied to this system instead.

Skill Crystals unlock nodes, and they come from three sources:

• Quests
• Daily rewards
• Ranked Wins

Crystals are limited, and later nodes get expensive fast. Here's the critical warning: resetting your skills costs 5,000 Gems. That's a massive cost compared to normal upgrades, so don't dump Crystals into random nodes. Decide what role a unit should play before you commit.

Auto Delete

Auto Delete automatically clears unwanted units while you farm. If you've ever stopped mid-grind to manually trash junk pulls, this is a pure quality-of-life win. Set your filters early and adjust them as your collection goals change.

AFK Server

The AFK Server gives passive progression while you're away from the keyboard. Check exactly what rewards it produces before relying on it, but if you're the type to leave Roblox running in the background, it's free progress you'd otherwise miss.

New Codes: 2,400 Gems and 11 Skill Crystals

Redeem these before you spend anything else. The four codes shipped with Update 3 are:

Combined, that's 2,400 Gems and 11 Skill Crystals — enough to make real progress on the Skill Tree without spending a dime. Community roundups also list additional codes like OCTOBER3 and SATURDAY, though rewards vary and codes expire, so redeem them the moment you log in. Enter them exactly as written in the in-game code menu.

What to Do First: Priority Order

If you're starting the Mongol update fresh, follow this route to avoid wasting resources:

1. Redeem all codes. Free Gems and Crystals first, always.
2. Open the Skill Tree. Understand the nodes available before spending Crystals.
3. Start the Mongol Battle Pass. Check quests for Nökör (tier 6), Bataar (tier 18), and Khorchin (tier 26).
4. Check your inventory for Mace and Pikeman. These now evolve into Morningstar and Phalangite.
5. Set up Auto Delete. Filter out units you don't want before you start farming.
6. Save Gems for Laestrygonian and Myrmidon. Check the banner before pulling — not every new unit is summonable.
7. Use the AFK Server whenever you're not actively playing.

Avoid skill resets unless absolutely necessary. At 5,000 Gems a pop, a single mistake can wipe out your entire code haul and then some.

Is the Mongol Update Worth Coming Back For?

Yes — this is the most substantial update Command an Army has received. The free Battle Pass alone gives 50 quests of structured progression, the Skill Tree adds a genuine long-term investment layer, and Laestrygonian gives whales and grinders alike a reason to keep pulling. The evolutions for Mace and Pikeman are a smart touch that rewards veteran players who kept old units around.

The main friction point is the summon economy. A 0.01% rate on the headline unit means most players will never see Laestrygonian without serious luck or spending, and skip costs add up quickly (community testing showed five skips costing 121 Gems). Budget accordingly, and let the Battle Pass and evolutions carry your roster in the meantime.
