- Reward farming relies on completing raids consistently to unlock exclusive units and evolve items.
Understanding All Star Tower Defense Raid Mechanics
Raids in All Star Tower Defense (ASTD) represent the pinnacle of cooperative and solo gameplay. Unlike standard story modes or infinite trials, raids are structured as high-intensity gauntlets where players face relentless waves of enemies, complex boss mechanics, and strict time limits. Success in a raid requires more than just powerful units; it demands strategic foresight, an understanding of spawn patterns, and the ability to adapt your defense layout on the fly.
The core objective in any ASTD raid is to protect your base from being overwhelmed. Enemies follow predetermined paths, and if too many reach your base, the raid ends in failure. To secure a victory, players must deploy a roster of upgraded characters, manage their in-game economy efficiently, and exploit elemental advantages whenever possible.

Before attempting high-level raids, ensure your units are at least level 150. Entering an All Star Tower Defense raid with under-leveled characters will severely handicap your damage output and survivability.
Raid Types and Difficulty Tiers
Different raids offer varying levels of challenge and unique reward pools. Knowing which raid to tackle based on your current unit roster is critical for efficient progression.
| Raid Name | Recommended Level | Key Mechanic | Primary Reward |
|---|---|---|---|
| Otherworld | 150+ | Heavy boss armor | Evolve items |
| Farm Raid | 100+ | High enemy count | Gold and Gems |
| Event Raid | 125+ | Special modifiers | Limited units |
Best Units for Raid Modes
Selecting the right units can make or break your All Star Tower Defense raid experience. Because raid enemies often possess massive health pools and heavy armor, you need characters that excel in either single-target burst damage or wide-area-of-effect (AoE) clears. Hybrid units are especially valuable as they can target both ground and air enemies.
When building your raid team, aim for a balanced composition. You generally want at least one primary DPS unit, a support character that provides damage buffs, and a unit capable of slowing or stunning enemies to control the crowd.
Top Tier DPS
- Burst damage specialists
- Ideal for melting raid bosses
- Requires high manual upgrade priority
AoE Clearers
- Wide attack radius
- Essential for early wave clearing
- Prevents base being swarmed by trash mobs
Support/Buff Units
- Damage amplification
- Speeds up team DPS significantly
- Low deployment cost
Unit Role Breakdown
Understanding the specific role each unit plays in your raid formation ensures you maximize your damage per second (DPS) across all waves.
| Unit Role | Function | Placement Strategy | Upgrade Priority |
|---|---|---|---|
| Primary DPS | Maximum single-target damage | Near the longest path U-turn | Highest |
| Secondary DPS | Consistent AoE damage | Middle of the map | High |
| Support | Buffs allied damage | Within range of DPS units | Low |
| Crowd Control | Slows or stuns enemies | Near the base or spawn | Medium |
Do not deploy all your units at the very beginning. Save in-game currency to quickly upgrade your Primary DPS to their max level before the first mini-boss spawns. A fully upgraded single unit is often more effective than several partially upgraded ones.
Step-by-Step Solo Raid Walkthrough
Soloing an All Star Tower Defense raid is a true test of game knowledge. Without teammates to share the economic burden or cover multiple lanes, your unit choices and upgrade timings must be flawless. Follow these steps to establish a winning solo strategy.
Economic Setup
Start the raid by deploying low-cost farm or economy units. Your goal in the first 3 waves is to accumulate as much gold as possible without leaking enemies. Place a cheap AoE unit near the spawn to handle initial waves while your economy scales up.
DPS Deployment
Once you have a stable gold income, deploy your primary DPS unit in a location that covers the longest portion of the path. Focus all your resources on upgrading this unit to its maximum potential before placing any additional attackers.
Boss Preparation
Before the boss wave arrives, ensure your support units are placed and buffing your main attackers. If the boss has elemental resistance, double-check that your primary DPS is not dealing heavily resisted damage.
Final Wave Execution
During the final waves, use your accumulated gold to place secondary DPS units near your base as a safety net. Micro-manage your units' abilities if they have active skills, timing your bursts to align with the boss's appearance.
Soloing the All Star Tower Defense raid means you do not have to share the final rewards. While it is significantly harder, it is the most efficient way to farm exclusive evolve items if you have a maxed-out meta unit.
Team Coordination and Multiplayer Tactics
Playing an All Star Tower Defense raid with a team introduces a layer of coordination that can drastically ease the difficulty. However, poor communication can lead to overlapping unit buffs, wasted economy, and disorganized defenses.
In multiplayer raids, assign specific roles to each player. One player should focus entirely on economy and support, while the others bring the heavy-hitting DPS units. This division of labor allows the team to max out key units much faster than everyone trying to deploy their own full roster.
Multiplayer Role Assignment
| Player Role | Responsibility | Recommended Units | Gold Priority |
|---|---|---|---|
| Support | Economy and Buffs | Money units, Damage buffers | Low (Shares gold) |
| DPS 1 | Single-target focus | Top-tier Meta units | High |
| DPS 2 | AoE and Crowd Control | Hybrid attackers, Stun units | Medium |
Support unit buffs generally do not stack if they are the exact same character. Communicate with your team to ensure you are bringing different support units to maximize the overall damage output of the group.
Raid Rewards and Farming Efficiency
The primary reason players grind the All Star Tower Defense raid is for the exclusive rewards. Raids are typically the only source for rare evolution items, special cosmetics, and occasionally, limited-time units. Understanding the reward structure helps you prioritize which raids to spend your daily energy on.
Maximizing your farming efficiency means minimizing the time spent per run while maximizing the reward yield. If you are strong enough to carry lower-level players, doing so can sometimes yield faster clear times than struggling through a higher difficulty with an under-leveled team.
Pre-Raid Preparation Checklist:
- Ensure primary DPS unit is at least level 150
- Check unit elements against raid enemy resistances
- Clear inventory space for evolution items
- Coordinate roles with teammates in multiplayer
- Verify daily energy reserves before starting
Reward Drop Rates
| Reward Type | Drop Chance | Raid Difficulty | Usage |
|---|---|---|---|
| Common Token | High | Normal / Hard | Basic summons |
| Rare Relic | Medium | Hard / Extreme | Unit evolution |
| Exclusive Shard | Low | Extreme | Limited unit unlocks |
Raids cost energy to attempt. If you fail a run, you do not get a refund. Always ensure your team is capable of clearing the All Star Tower Defense raid difficulty you select to avoid wasting your limited daily energy.
Advanced Tips and FAQ
Mastering the All Star Tower Defense raid goes beyond basic unit placement. Advanced players utilize game mechanics like spawn manipulation, range overlapping, and precise ability timing to squeeze out every last drop of damage. Always look for corners where enemies are forced to turn, as these spots maximize the time your units spend attacking the same target.
Q: What is the best element for the Otherworld Raid?
The Otherworld Raid features enemies with diverse resistances. It is generally recommended to use units that deal neutral damage or have built-in true damage mechanics, rather than relying heavily on a single elemental type.
Q: Can I solo the All Star Tower Defense raid?
Yes, soloing is entirely possible. As shown in the embedded walkthrough, a single player with a max-level meta unit, proper economic management, and optimal placement can clear even the hardest raids.
Q: Do raid units need to be maxed out?
While you do not need every unit maxed, your primary damage dealer should be at its maximum level and upgrade tier. Under-leveled units will struggle to break through the heavy armor of raid bosses.
Q: How often can I play raids?
Raids are gated by an energy system. You receive a set amount of energy daily, meaning you have a limited number of attempts each day unless you use premium currency to refill your energy bar.
Place your units so their attack rings overlap on a single tile. When enemies pass through this overlapping zone, they take damage from all units simultaneously, creating a kill zone that can instantly delete high-health targets.
