How To Get the Best Starter Unit in ASTD X Roblox (March 2026)

Starting your journey in All Star Tower Defense X can feel overwhelming with dozens of units to choose from and limited resources to spend. But here’s a secret that veteran players have been using since launch day – there’s one starter unit combination that absolutely dominates the early game and can carry you through the first story chapters without breaking a sweat. I’ve tested every possible starter combination, and today I’m revealing the ultimate strategy that will give you an unstoppable advantage from day one.

Best Starter Roblox ASTD X Unit Overview

Starter Unit	Requirements	Power Level	Difficulty to Obtain
Naruto + Sasuke Team-up	2x 4-star units	⭐⭐⭐⭐⭐	Medium
Kosuke (TS)	1x 4-star unit	⭐⭐⭐⭐	Easy
Uru	1x 3-star unit	⭐⭐⭐	Very Easy
Stampede	1x 4-star unit	⭐⭐⭐⭐	Medium

The Ultimate ASTD X Starter Unit: Naruto + Sasuke Team-Up

When you place Naruto and Sasuke adjacent to each other on the battlefield, magic happens. These two 4-star units merge into a single powerhouse that rivals many 5-star units in terms of raw power and utility. This isn’t just any ordinary unit – it’s a game-changer that transforms your early game experience from a struggle to a breeze.

Why This Team-Up Dominates?

The Naruto + Sasuke fusion brings several game-breaking advantages:

1. Massive AoE Coverage Unlike most starter units that struggle with crowd control, this team-up unit boasts an impressively wide attack radius. When you place Naruto and Sasuke next to each other on the field, you’ll unlock their team-up ability, which merges them into one upgraded unit. This fused unit has several advantages: Strong AoE (Area of Effect): Unlike many starter units with small AoE attacks, this team-up unit has a wide attack radius.

2. Multi-Hit Shield Breaker Early waves often feature shielded enemies that can slip through weak defenses. The combined unit attacks multiple enemies at once and can even bypass enemy shields, making it effective against various enemy types.

3. Incredible Base Damage You don’t need to spend precious resources upgrading immediately. Even at upgrade zero, the unit does impressive damage, enough to clear early game content easily.

4. Excellent Scaling Potential As you progress and gather upgrade materials, this unit only gets stronger. As you upgrade this unit, its damage increases significantly, reaching thousands of DPS at higher levels.

How to Get the Naruto + Sasuke Team-Up in All Star Tower Defense X?

Getting this powerful starter unit is simpler than you might think. Here’s my proven step-by-step strategy:

Step 1: Understand the Summoning System

In ASTD X, units are obtained through the banner summoning system. There are two banners, X and Y, which rotate every 60 minutes. You can only get the featured units from them. This means timing is crucial when hunting for specific units.

Step 2: Farm Gems Efficiently

Before you can summon, you’ll need gems. Here are the fastest ways to accumulate them as a new player:

• Complete story mode chapters (first-time rewards are generous)
• Use active ASTD X codes for free gems
• Participate in daily quests
• Join an active guild for bonus rewards

Step 3: Wait for the Right Banner

Since Both Naruto and Sasuke are four-star units that are commonly found in the game’s banners, making them very accessible for new players., you won’t have to wait too long. Check both X and Y banners every hour until you spot either unit featured.

Step 4: Optimize Your Summons

Here’s a pro tip that most guides miss: always do 10x summons instead of singles. 10x Summons are more worth it, so don’t do 1x summons. There is also a 100-pull 5-star pity. So, if you don’t get a 5-star unit in 100 pulls, your next pull will be a guaranteed 5-star.

Step 5: Activate the Team-Up

Once you have both units:

1. Enter any game mode (I recommend starting with Story Mode Chapter 1)
2. Place Naruto on the field, then place Sasuke right next to him.
3. When placed side-by-side, a prompt will appear allowing you to combine the two into the fused team-up unit.
4. Confirm the fusion and watch your new unit demolish waves!

Alternative Starter Units Worth Considering

While the Naruto + Sasuke team-up is undoubtedly the best, you might get unlucky with banner rotations. Here are solid alternatives to keep you progressing:

Kosuke (TS) – The Reliable 4-Star

Kosuke (TS) is the best 4-star unit with excellent range and decent DPS. What makes Kosuke special is his consistency – he performs well in almost any situation without requiring specific team compositions.

Pros:

• Available as a starter in some cases
• Excellent range for a 4-star
• Can team up with Zaruto (Sage) for even more power

Cons:

• Lower DPS compared to the Naruto + Sasuke fusion
• Requires more strategic placement

Uru – The Budget Beast

For absolute beginners or those with terrible summoning luck, Uru stands out as the best 3-star option. Uru is the best 3-star unit with excellent single-target DPS and range on placement.

Pros:

• Extremely easy to obtain
• Cheap to upgrade
• Surprisingly effective for a 3-star

Cons:

• Falls off in mid-game content
• Limited AoE capabilities

Stampede – The Crowd Controller

Stampede has very good range and decent DPS. This 4-star unit excels at handling large groups of enemies, making it perfect for wave-heavy early chapters.

Pros:

• Wide AoE attacks
• Good damage scaling
• Multi-hit attacks for shield breaking

Cons:

• More expensive to upgrade
• Requires specific positioning for optimal performance

Advanced Tips for Using Your Starter Unit

Placement Strategy

The key to maximizing your starter unit’s effectiveness lies in strategic placement:

1. For Naruto + Sasuke Team-Up: Place them at chokepoints where paths converge to maximize AoE coverage
2. Air Wave Management: The fused unit doesn’t attack air enemies, so having Sasuke alone to cover air waves can be a smart strategy.
3. Upgrade Priority: Focus on damage upgrades first, then range, and finally attack speed

Resource Management

As a new player, resources are limited. Here’s how to optimize:

• Don’t Worry About Upgrading Immediately: The unit is strong even at upgrade zero and can clear early levels easily. Save your resources for when you need stronger upgrades later.
• Focus on one main unit initially rather than spreading upgrades thin
• Save trait rerolls for when you understand the system better

Team Composition Evolution

Your starter unit won’t carry you forever. Plan for these transitions:

Early Game (Chapters 1-5):

• Naruto + Sasuke Team-Up
• One additional DPS unit
• Basic support unit

Mid Game (Chapters 6-10):

• Keep your starter as secondary DPS
• Add a proper 5-star main DPS
• Include buff/debuff supports

Late Game:

• Starter unit becomes situational
• Full 5-star team with synergies
• Optimized traits on all units

Understanding the Summoning System

To consistently get good units beyond your starter, master these summoning mechanics:

Banner Rotation Schedule

Each banner: 3x 3-star, 2x 4-star, 1x 5-star units. Banners refresh hourly, so patience pays off. Set timers if you’re hunting specific units.

Pity System Explained

The pity system is your safety net: if you don’t get a 5-star unit in 100 pulls, your next pull will be a guaranteed 5-star. This applies per banner, so track your pulls carefully.

Special Summons and Capsules

You can get special Capsules that work the same as regular banner summons but with different unit pools. Save these for events featuring limited units.

Common Mistakes to Avoid

Through helping countless new players, I’ve noticed these recurring errors:

1. Summoning on Every Banner: Just because a banner refreshes doesn’t mean you should pull. Wait for units you actually need.
2. Ignoring Team-Ups: Many players don’t realize certain units can combine. Always check for team-up potential.
3. Neglecting 3-Star Units: While 5-stars are flashy, well-built 3-star teams can clear significant content.
4. Poor Trait Management: Random trait rolling wastes resources. Research optimal traits before rerolling.
5. Rushing Through Content: Take time to understand mechanics. The game rewards strategic thinking over mindless grinding.
