What's New in the Mongols Update

The Mongols update (also called the Laestrygonian update in some patch notes) introduced more content than any previous drop. According to the official Roblox game page, the update went live on October 5, 2026, and the game now sits at over 58 million visits with nearly 850,000 favorites.

Here's the full breakdown of what was added:

FeatureDetails
New Units7 total (3 via summons, 3 via battle pass, 1 event unit)
First Five-Star UnitLaestrygonian (700 HP, 120 base damage)
Skill TreePer-unit upgrade paths using skill crystals
Battle Pass50 levels with exclusive units and rewards
New MapMountain terrain with flanking routes
Guild SystemUnlocks at battle pass level 35 (15,000 gems)
AFK ServerPassive rewards while idle

The update also added two new evolutions and an auto-delete feature for managing your unit inventory. Community reports suggest the mountain map heavily favors ranged and cavalry units because of its narrow chokepoints and elevated positions.

All New Mongol Units and What They Do

The seven new units span multiple tiers and roles. Three come from the standard summon pool, three are battle pass exclusives, and one is tied to the event. Here's what each one brings to the battlefield.

Summon Pool Units

The summonable units are the easiest to obtain if you have gems saved up, though the drop rates are brutal. Player experience reports put the five-star Laestrygonian at roughly a 0.3% pull rate.

UnitTierRoleKey Stats
Laestrygonian5-StarHeavy Infantry700 HP, 120 damage, slow movement
Myrmidon4-StarHybrid23 damage, 20 speed, shield ability
Scout Archer3-StarRangedFast, low HP, harassment role

The Laestrygonian is the headline unit. It can one-shot cavalry, shrugs off most melee attacks, and functions as a mobile fortress. Its main weakness is speed — it moves about as fast as a standard player character, so you need to position it carefully before committing to a push.

The Myrmidon is a solid mid-tier pick. Its hybrid classification means it can hold a line with its shield ability while still dealing respectable damage. Community testing shows it performs best when you use the hold command to force enemies into wasting their rush abilities on your shields.

Battle Pass Units

Three units are locked behind the battle pass, including the fan-favorite Hun horse archers at level 26. These units cannot be obtained through summons, so if you want them, you're grinding or paying.

UnitUnlock LevelRole
Hun Horse Archer26Ranged Cavalry
Necore38Elite Infantry
Mongol Warrior50Frontline Bruiser

The Hun horse archers are the standout. They form a circle formation around your commander when told to follow, auto-attack enemies from extreme range, and can kite slower units indefinitely. Their damage is low per arrow (around 22), but it adds up fast, and they slow enemy movement with each hit.

The catch? Horse archers die almost instantly if caught. One touch from a lancer or samurai eliminates them. You need to constantly reposition and never let them stand still in melee range.

How the Skill Tree Works

The skill tree is the update's biggest long-term progression system. It sits next to the ascension and evolve menus on each unit's detail screen. You spend skill crystals to unlock nodes that boost stats like damage, attack speed, and accuracy.

Skill crystals come from three sources:

  • Daily quests and battle pass quests
  • Daily login rewards
  • Ranked match victories

Best Skill Tree Paths by Unit Type

Not every node is worth unlocking. Based on community testing and player reports, here are the recommended paths:

Unit TypePriority NodesSkip
Lancers/AttackersRush damage, charge powerDefense nodes
Shield/Blocker UnitsShield duration, block rateDamage nodes
ArchersAttack speed, accuracyMovement speed
Heavy InfantryAttack speed, HPRush abilities

For the Laestrygonian specifically, maxing out attack speed is the top priority. Its base damage is already absurd — making it swing faster turns it into an unstoppable force. One player reported getting a 5% attack speed buff for 10 seconds after fully upgrading the relevant node, which sounds small until you see it in action.

Don't waste crystals on defensive nodes for units that are meant to deal damage. The skill tree rewards specialization, not balanced builds.

Battle Pass Rewards and Is It Worth It?

The battle pass costs Robux to skip levels (roughly 1,200 Robux for five skips), but you can grind the entire thing for free if you're patient. Here's what you actually get at each milestone.

LevelReward
1-10Gems, skill crystals, common units
26Hun Horse Archer (exclusive unit)
35Guild creation unlock
38Necore (exclusive unit)
50Mongol Warrior (exclusive unit)

The battle pass also includes daily quests that refresh each day. These range from "kill 80 enemies using melee troops" to "defeat six enemy commanders" to "capture five objectives." Completing them levels you up faster than just playing matches.

Is it worth buying skips? That depends on how badly you want the horse archers. They're genuinely overpowered in the right hands, but they require practice to use effectively. If you're not comfortable with micro-managing fast units, save your Robux and grind the pass naturally.

Tips for Winning With Mongol Units

The Mongols update rewards aggressive, mobile playstyles. Here are the most effective strategies based on community testing and player experience.

Horse Archer Kiting

The Hun horse archers are designed for harassment, not frontline combat. The ideal loop is:

  1. Position your horse archers behind your main army
  2. Let them auto-attack enemy units from max range
  3. When enemies charge toward them, retreat while continuing to fire
  4. Once the enemy is weakened and out of position, send in your melee units to clean up

This strategy works especially well against slow units like immortals and Spartans. They can't catch you, and every second they chase is a second your other units are capturing points.

Laestrygonian Deployment

The five-star giant is a game-ender if you keep it alive. Treat it like a siege weapon:

  • Never send it in alone — support it with cheaper units
  • Position it behind your front line so it can attack over your troops
  • If it takes heavy damage, retreat and heal at base
  • Don't let it die — the respawn timer is over 100 seconds

One player reported getting 200+ kills in a single match by protecting their Laestrygonian and letting it rack up damage from behind a shield wall.

Mountain Map Control

The new mountain map has two flanking passages that most players ignore. Send a small group of fast units through these routes while your main army pushes the center. You can capture back-line points while the enemy is distracted, forcing them to split their forces.
