How to Get All New Units in All Star Tower Defense X Update 2?

1. Banner Units: Chrolo and Kilua

Chrolo (Spider Boss – Unbound)

Chrolo is only obtainable through Banner X and represents one of the most powerful additions to the Unbound tier. This meta-defining unit has already changed how players approach both PvP and Infinite Mode.

How to get Chrolo:

• Banner: Exclusively Banner X (rotates every 60 minutes)
• Cost: 50 gems per single summon, 450 gems per 10x summon
• Pity System: 100-pull guarantee for 5-star (Unbound included)
• Best Strategy: Wait for Banner X rotation and use All Star Tower Defense X codes to maximize gem count

Kilua (Killer)

Kilua is available in Banner Y and can evolve into a 5-star unit, making him one of the more accessible new additions while still offering significant power potential.

How to get Kilua:

• Banner: Banner Y (alternates with Banner X every 60 minutes)
• Evolution Potential: Can be evolved to 5-star rarity
• Recommended Traits: All Star, Genesis, or Bloodlust for maximum effectiveness
• Team Synergy: Pairs excellently with speed-based compositions

Pro Tip: I recommend using the 10x summons over single pulls for better value. With the current active codes providing over 3000 gems, you’ll have plenty of attempts to secure both banner units.

2. Evolution Unit: Asta (Anti-Magician Evolution)

Asta represents a new evolution for the existing Anti-Magician unit, offering players who already own the base unit an immediate upgrade path without additional summoning.

How to get Asta:

1. Obtain Anti-Magician (if you don’t have it already)
2. Collect Evolution Materials:
   • 5 Anti-Magician copies
   • 3 Mage Staff items
   • 2 Ghost I (Orange)
   • 2 Ghost I (Rainbow)
   • 5,000 Gold
3. Navigate to Units Tab
4. Select Anti-Magician
5. Click “Evolve” button
6. Confirm evolution with required materials

Material Farming Tips:

• Ghost I (Orange/Rainbow): Farm Daily Challenge – Expert Mode on rotation days
• Mage Staff: Obtained through Trial rewards and special events
• Gold: Use money farming units like Ramen Grill Master for efficient gold generation

3. Fireworks System Units: The Limited Trinity

The Fireworks System introduces three exclusive units with limited stock of 20,000 total, making them rare collectibles. This system works similarly to Void Bags but with much more limited availability.

How to Access Fireworks System:

1. Complete Story Mode chapters to unlock Firework drops
2. Visit Summer Event NPC in the main lobby
3. Exchange Fireworks for unit chances
4. Monitor stock levels – once 20,000 are claimed globally, they’re gone forever

Shark Ninja

• Type: 4-Star Ground Unit
• Specialization: High-speed attacks with water-based abilities
• Best Traits: Sharpshooter, Zenkai III, or Dexterity III
• Meta Role: Excellent early-game carry with scaling potential

Mercury Guardian

• Type: 4-Star Hill Unit
• Specialization: Defensive support with area denial
• Best Traits: All Star, Corrupted, or Tank (for new players)
• Meta Role: Strategic placement unit for controlling enemy movement

Silent Swordsman

• Type: 4-Star Ground Unit
• Specialization: Single-target elimination with stealth mechanics
• Best Traits: Bloodlust, Genesis, or All Star
• Meta Role: Boss killer and high-value target elimination

Fireworks Farming Strategy:

• Prioritize Story Mode completion for consistent Firework drops
• Focus on higher difficulties for better drop rates
• Check Summer Event NPC daily for bonus Firework opportunities
• Act quickly – with global stock limits, these units won’t last long

4. Summer Box Exclusive: Water Goddess

Water Goddess is the exclusive unit from the Summer Box and is not found in banners, fireworks, or trials, making it truly unique to this limited-time event.

How to get Water Goddess:

1. Locate Summer Event area in the main lobby
2. Complete Summer Event tasks (varies daily)
3. Earn Summer Points through event participation
4. Claim Summer Box when you have sufficient points
5. Open box to receive Water Goddess

Summer Event Tasks Include:

• Complete specific Story Mode chapters
• Win matches in certain game modes
• Use particular unit types in battles
• Participate in community challenges

Important: The Summer Event is time-limited and will end with the current update cycle. Don’t delay claiming your Summer Box as there’s no indication this event will return.

5. Trial Exclusive: Alligator (Unbound)

Alligator can only be obtained from the new Trials, adding a challenge-based method to your collection. This represents the most skill-intensive acquisition method in Update 2.

How to get Alligator:

1. Access Trials area (Serpent’s head location in lobby)
2. Choose between Trial modes:
   • Regular Mode: Allows traits/stats/hidden potential, 1% drop rate
   • Strategic Mode: No traits/stats/hidden potential, 10% drop rate, higher enemy HP
3. Complete Trial successfully
4. Repeat until unit drops (expect multiple attempts)

Trial Strategy for Alligator:

• Recommended for Strategic Mode: Higher drop rate offsets difficulty
• Required Units: Focus on top-tier units without trait dependencies
• Team Composition: Balanced DPS, support, and crowd control
• Patience Required: Even with 10% drop rate, expect 10-20 attempts average

Trial Preparation Checklist:

• Level 100+ core units
• Multiple shield-breaking units
• Strong economy foundation
• Crowd control options
• Backup DPS units

6. Buffed Unit: Ace

While Ace received a major stat buff rather than being a new unit, the improvements are substantial enough that existing Ace owners should revisit this unit immediately.

Ace’s Update 2 Improvements:

• Damage: Increased by approximately 40%
• Range: Extended reach for better positioning
• SPA (Speed): Faster attack rate for higher DPS
• Special Abilities: Enhanced burn effects and area control

How to utilize buffed Ace:

1. Check your unit collection for existing Ace
2. Re-evaluate trait combinations with new stats
3. Test in current meta compositions
4. Consider skill tree paths that maximize new strengths

FAQ’s

How many new units are in ASTD X Update 2?

Update 2 introduces 7 new units: Chrolo, Kilua, Asta evolution, Shark Ninja, Mercury Guardian, Silent Swordsman, Water Goddess, and Alligator, plus significant buffs to existing Ace.

Which Update 2 unit is the strongest?

Chrolo (Spider Boss – Unbound) currently dominates the meta due to his Unbound tier status and exceptional stats. However, Water Goddess offers unique utility that makes her invaluable for specific team compositions.

Are the Fireworks units worth getting?

Absolutely! With only 20,000 total stock globally, these units represent rare collectibles that may never be available again. Even if they’re not immediately meta-defining, their scarcity alone makes them valuable.

How long do I have to get these units?

Banner units (Chrolo, Kilua) are permanent additions. Fireworks units last until global stock depletes. Summer Box units (Water Goddess) are limited to the current event cycle. Trial units (Alligator) are permanent but require skill to obtain.

Can I get multiple copies of limited units?

The Fireworks and Summer Box systems typically allow one copy per player, though this may vary by specific implementation. Banner and Trial units can be obtained multiple times for evolution/ascension purposes.

What’s the drop rate for Alligator in Trials?

Strategic Mode offers 10% drop rate while Regular Mode provides 1% drop rate. Most players find Strategic Mode more efficient despite the increased difficulty.

Do I need specific traits for new units?

While traits significantly enhance performance, most new units remain viable with common traits. Prioritize All Star, Genesis, and Bloodlust for optimal performance, but don’t let trait requirements prevent you from using these units.

Can I trade for Update 2 units?

Currently, ASTD X doesn’t support player-to-player trading. All units must be obtained through their designated acquisition methods.

Are Update 2 units better than original units?

Power levels vary by specific unit and role. Chrolo and Alligator definitely rank among the strongest available, while Fireworks units serve as solid mid-tier options. Integration with existing teams often matters more than raw power.

Will these acquisition methods change in future updates?

While banner units typically remain available, event-exclusive methods may be modified or replaced. Limited-time opportunities should be prioritized to avoid permanent unavailability.
