Best Strategy to Beat Summer Raid 1 in ASTD X Update 2
After countless attempts and analyzing the mechanics extensively, I’ve discovered that Summer Raid 1 stands out because enemy HP does not scale with the number of players. This means the health stays the same whether you bring two players or six — and trust us, you’ll want the full six. Let me share the exact strategy that’s helped me and my team achieve consistent victories.
Why Summer Raid 1 is the Toughest Challenge Yet?
The latest All Star Tower Defense X update introduces one of the toughest challenges yet — Summer Raid 1. Unlike previous raids, this one isn’t designed to be completed solo. I’ve witnessed countless players attempt this raid with insufficient team sizes and fail repeatedly. The brutal truth is that this raid fundamentally changes how we approach ASTD X content.
The core difference lies in the map design. The map layout features three separate paths, and you need at least two players per path to cover all entrances. Trying to solo this or play with fewer than five players will almost guarantee failure. I learned this the hard way during my first dozen attempts!
Essential Team Formation Strategy
Minimum Team Requirements:
- 5-6 players total (6 strongly recommended)
- 2 players per path for optimal coverage
- Coordinated communication (Discord essential)
- Pre-planned unit distributions
I can’t stress this enough: if you’re short on friends to team up with, head over to the official Discord server to find reliable teammates. The official ASTD Discord has dedicated channels for raid formations where you can find experienced players.
Optimal Unit Selection and Builds
Red Unit Advantage (Current Meta)
The game-changing factor in Summer Raid 1 is the rotating unit buffs. Units receive buffs based on color themes, which rotate every 4 hours. Currently, Red units are boosted, so make sure your team is stacked with strong red-themed characters.
Top Red Units for Summer Raid 1:
- Akainu – Obtained through Trial 2, massive fire damage
- Zaruto (Beast Cloak) – High DPS with excellent range
- Explosion Artist – AoE specialist for crowd control
- Jin Sung – Bleed damage synergy with red buffs
All Star Units: Your Secret Weapons
Having All Star units can make a big difference. These units seem to perform better in this raid, offering more reliable damage and crowd control. Based on my extensive testing, these All Star units excel in Summer Raid 1:
- Ulquiora with Genesis trait – Primary DPS
- Esdeath from Trial 1 – Crowd control specialist
- Broly – Backup damage dealer
- Mihawk – Range support
Support Unit Integration
Deploy Support Units – Slow and freeze units are crucial in the early waves. Use support to manage enemy mobs and reduce pressure on your teammates.
Essential Support Setup:
- Blackbeard – Enemy movement control
- Mysterious X – Stun capabilities for crowd control
- King Kaoe – 75% ally damage boost (warning: destroys base shield)
- Xero – Meta support for all game modes
Phase-by-Phase Execution Strategy
Early Waves (1-10): Foundation Building
Economic Priority:
- Place farming units immediately
- Focus on economy before combat units
- Coordinate with teammates for path coverage
- Save cash for mid-game transitions
Unit Placement:
- Path 1: Primary DPS + Support
- Path 2: All Star unit + Economy
- Path 3: Backup DPS + Crowd Control
Mid Waves (11-20): Scaling and Control
This phase demands perfect coordination. Enemy types become increasingly diverse, and shielded enemies appear (around wave 12), place Ichigo and/or Zoro to break their shields quickly.
Shield Breaking Strategy:
- Ichigo – Multi-hit AoE shield destruction
- Zoro – Alternative shield breaker
- Slayer Mage – Top-tier shield counter
Boss Phase (Wave 21): The Ultimate Test
The moment that separates successful teams from failures. On Wave 21, a boss will spawn — likely Crocodile or Zeke, depending on the raid cycle. Three barriers will appear, one at each entrance. You must destroy all three barriers to damage the boss.
Critical Boss Mechanics:
- Barrier Destruction – All three must fall simultaneously
- Team Coordination – Have your team split up to handle these as quickly as possible — 2 players per path will be perfect for this
- Cash Management – Save at least 50,000 cash to reposition your strongest damage units near the boss location. The boss spawns on a random island, and being able to quickly react is key to winning
Advanced Positioning and Skill Tree Optimization
Terrain Advantages
Elevation plays a crucial role in Summer Raid 1 success. Based on my analysis of top-performing teams:
- Hill units gain +15% range on elevated terrain
- Ground units benefit from central positioning
- Flying enemies require specific counter-positioning
Skill Tree Optimization
Damage Path (Red) – Essential for DPS units:
- Prioritize critical hit multipliers
- Focus on piercing damage for multi-enemy waves
- Maximize base damage increases
Range Path (Blue) – Ideal for support positioning:
- Extended coverage for crowd control
- Better path monitoring capabilities
- Enhanced AoE effects
Speed Path (Green) – Situational but powerful:
- Faster ability cooldowns
- Quick economic scaling
- Rapid response capabilities
Common Mistakes and How I Fixed Them?
Mistake #1: Insufficient Team Size
- Problem: Attempting with 2-3 players
- Solution: Always recruit 5-6 dedicated teammates through Discord
Mistake #2: Ignoring Color Rotation Buffs
- Problem: Using non-red units during red buff phase
- Solution: Check rotation timer and adapt unit selection accordingly
Mistake #3: Poor Cash Management
- Problem: Spending all resources before Wave 21
- Solution: Save at least 50,000 cash to reposition your strongest damage units near the boss location
Mistake #4: Uncoordinated Barrier Destruction
- Problem: Focusing on single barriers
- Solution: Synchronized 2-player assault on each barrier
