Always check the official Discord or in-game announcements for banner rotations. Summoning right before a rotation can sometimes result in missing out on a featured unit you were aiming for.

Breakdown of Summoning Odds

The probability of pulling specific rarities is fixed, but it differs significantly between standard banners and special events. Knowing these percentages helps you calculate the expected value of your gem expenditure.

5-Star2%2%7-9%
4-Star8%10%25-30%
3-Star25-30%23-28%N/A

As shown in the table above, Banner Z is significantly more generous for higher-rarity units, though it carries a higher cost per spin. For those utilizing the Special Summon banner, featured units have a static 1.5% chance, while the global rate for other units is 98.5%.

Pity Reset Warning

Pity systems do not reset between banner switches for the same type (e.g., X and Y). However, leaving the server will reset your pity count. Always perform your full sequence of summons in a single session to avoid losing progress toward a guaranteed unit.

Mastering the Pity System

The pity system is your safety net in All Star Tower Defense X. It ensures that even the unluckiest players eventually obtain powerful units. For standard banners, the pity threshold is 80 summons, while Banner Z requires 140 summons for a guaranteed 6-star unit.

1

Accumulate Resources

Save at least 3,600 gems for standard banners or 12,600 gems for Banner Z to ensure you hit the pity threshold.

2

Select Your Banner

Verify the current banner rotation to ensure it contains the units you currently need for your loadout.

3

Perform Multi-Summons

Use the 10x summon option to benefit from the 10% gem savings, which drastically lowers the total cost of reaching pity.

4

Track Your Progress

Count your spins carefully. If you reach the pity limit, the game will automatically grant you the guaranteed rarity.

Optimization Strategies

Efficiency is key when dealing with RNG. Beyond just understanding the All Star Tower Defense X summon rates, you should focus on how you spend your currencies. Gold summons, for example, are essential for obtaining fodder units used in the evolution process.

Summoning Best Practices:

  • Only use gems on banners with high-tier units you need.
  • Always perform 10x spins to maximize gem efficiency.
  • Save Stardust for limited-time banners with 7-star potential.
  • Keep a reserve of Gold for evolving your primary units.
Smart Spending

Spending 150 Stardust on three multi-summons in the Special Banner grants you an extra 10x summon for free. This is the most efficient way to hunt for top-tier units without burning through your entire resource cache.

Frequently Asked Questions

Q: Do the All Star Tower Defense X summon rates change during events?

Generally, the base rates for standard rarities remain constant. However, featured units in Special Summons often have boosted individual odds during specific event windows.

Q: Does leaving the game reset my pity count?

Yes. All pity progress is tied to your current server session. If you disconnect or switch servers, your pity count for that banner will reset to zero.

Q: Is it worth pulling on Banner X if I have access to Banner Y?

Banner Y generally offers better 5-star units. Unless you are specifically hunting a unit exclusive to the current Banner X rotation, Banner Y is usually the better investment.

Q: Can I get secret units from Special Summons?

No. Secret units, which have a 1/2000 chance per spin, can currently only be obtained via standard banners and are not available in the Special Summon pool.
