Step-by-Step Progression Guide

Unlocking your first All Star Tower Defense 7 Stars unit requires a systematic approach. Jumping straight into the hardest raids will only drain your resources. Follow this structured progression path to ensure steady advancement toward your 7 Star goals.

1

Clear Story Mode

Focus entirely on completing the Story Mode stages. This not only provides you with essential gems but also unlocks the Star Pass, which guarantees you an easy 7 Star unit simply by playing the game normally.

2

Build a 6 Star Foundation

Use your gems to summon strong 6 Star units. You cannot reliably farm 7 Star materials without a solid foundation of maxed-out 6 Star characters. Focus on units with Area of Effect (AoE) attacks.

3

Farm Singen and Spirit Raids

Once your team is ready, start grinding Singen Raid and Spirit Raid. These two modes offer the best access to multiple 7 Star upgrade items. Prioritize these over endgame content like Hell Raid.

4

Complete the Evolution

Gather the specific items required for your chosen unit. Once you have all the materials and the base unit at max level, head to the evolution chamber to unlock the 7 Star form.

Optimal Farming Strategy

The most efficient way to farm materials is during the 2x Drop Rate weekends. Wait for these events to use your raid tickets for double the rewards.

Advanced Tips and FAQ

Mastering the All Star Tower Defense 7 Stars system requires more than just knowing where to farm. Proper unit placement, understanding enemy pathing, and knowing when to use your active abilities are what separate casual players from top-tier defenders.

Placement Matters

Even a 7 Star unit can underperform if placed incorrectly. Always position your high-DPS units where they can hit multiple enemy pathing routes simultaneously.

Q: What is the absolute easiest 7 Star to get in All Star Tower Defense?

The easiest 7 Star units are those available through the Star Pass. You only need to play through Story Mode and accumulate pass points to unlock them. They require no complex raid strategies or rare material farming.

Q: Which raids should I prioritize for 7 Star materials?

You should prioritize Singen Raid and Spirit Raid. These two raids offer multiple attainable 7 Star units and have a moderate difficulty level, making them the most efficient use of your raid tickets compared to harder modes like Hell Raid.

Q: Can I get 7 Star units from Dual Raid or Six Eyes Raid?

Yes, but these raids typically only drop materials for one specific unit. While Dual Raid is easy enough, the limited reward pool makes it less efficient than Spirit or Singen Raids if you are looking to expand your overall 7 Star roster.

Q: Do I need max level units to attempt 7 Star raids?

While not strictly mandatory for every raid, having a team of max-level 6 Star units is highly recommended. Attempting these raids with underleveled characters will almost certainly result in a loss and waste your gems.
