The astd gacha system determines everything about how you build your roster, from your first free pull to the coveted 7-star exclusives that define endgame teams. Understanding the exact astd summon rates, the all star tower defense pity mechanics, and how the astd pity system tracks across banners is the difference between hoarding gems for months and pulling the unit you actually need. Because the Summon Gate rotates new units every hour — as confirmed on the official All Star Tower Defense Roblox page — knowing when to spend and when to save directly impacts your progression speed. This guide breaks down every rate, every guarantee, and every strategy you need to make your gems count.
Breaking Down the ASTD Gacha System Rates
The astd gacha system uses a multi-tier rarity structure that determines your odds of pulling each unit type. Unlike many Roblox tower defense games that hide their probabilities, ASTD displays the base rates directly in the Summon Gate menu, though the exact numbers shift slightly depending on which banner you pull from. According to community testing and player reports, the standard Gold Summon rates follow a consistent pattern that has remained stable through the 2026 updates.
| Rarity Tier | Base Rate | Typical Unit Examples | Notes |
|---|---|---|---|
| 3-Star | 58% | Common fodder units | Most frequent pull, useful for feeding |
| 4-Star | 30% | Rare support units | Solid mid-game options |
| 5-Star | 10% | Featured battle units | The astd 5 star guarantee threshold |
| 6-Star | 1.8% | High-tier damage dealers | Significant power spike |
| 7-Star | 0.2% | Exclusive meta-defining units | Extremely rare, banner-dependent |
The astd summon rates you see above represent the baseline for the standard Gold Summon. However, special banners like the Starhunt rotation and limited-time events adjust these numbers, often boosting the 6-star and 7-star rates slightly while reducing the 3-star pool. What matters most for your long-term strategy is understanding that the astd gacha system rewards volume over single pulls — the more summons you complete, the closer you get to the pity thresholds that guarantee higher rarity units.
How the Pity Counter Works
The all star tower defense pity system tracks your pulls across banners, though the exact mechanics differ from what many players initially assume. Based on community reports and verified testing, ASTD implements a soft pity system rather than a hard guarantee at a specific pull count. This means your odds of pulling a 6-star or 7-star unit increase gradually as you summon without success, rather than triggering a guaranteed drop at pull 50 or 100.
-
Soft pity begins around pull 30 on most banners, with rates increasing roughly 0.5% per pull
-
Hard pity exists at pull 100 for the featured 5-star unit, guaranteeing that specific character
-
Pity carries across same-type banners — if you pull 40 times on the Gold Summon and switch to a new Gold Summon rotation, your progress persists
-
Pity resets when you pull the featured unit or when the banner type changes entirely (e.g., Gold to Starhunt)
The astd pity system also interacts with the astd 5 star guarantee in a way that rewards patient players. Every 10-pull guarantees at least one 5-star unit, which means you should always save for multi-summons rather than spending gems one at a time. This guarantee stacks with the soft pity counter, creating a predictable floor for your spending.
Comparing Banner Types and Their Value
Not every banner in the astd gacha system offers the same value, and knowing which one to prioritize can save you hundreds of thousands of gems over a playthrough. The game currently features three main summon types, each with distinct rate tables and featured unit pools. According to the official game description, "new things appear in the Summon Gate and Emote Shop every hour," which means the featured units rotate frequently and you need to plan your pulls around the current rotation.
| Banner Type | Cost per Pull | 5-Star Rate | 6-Star Rate | 7-Star Rate | Best For |
|---|---|---|---|---|---|
| Gold Summon | 50 Gems | 10% | 1.8% | 0.2% | General roster building |
| Starhunt Banner | 100 Gems | 12% | 2.5% | 0.4% | Chasing featured exclusives |
| Special Event Summon | 150 Gems | 15% | 3% | 0.5% | Limited-time meta units |
The astd best banner to summon depends entirely on your current roster and gem reserves. For new players, the Gold Summon offers the best cost-to-value ratio because the lower price per pull means you hit the astd 5 star guarantee more frequently. Veterans with established teams should focus on Starhunt or Special Event banners, since the boosted 6-star and 7-star rates justify the higher gem cost when you are hunting specific meta units.
When to Save Gems Instead of Summoning
Understanding astd how to get gems for summon is only half the battle — knowing when to hold onto those gems matters just as much. The astd gacha system rotates featured units every hour, which creates natural spending windows that reward patience. Community data suggests that waiting for the right banner can effectively double your chances of pulling a top-tier unit, since the featured 7-star rate applies only to the specific unit on rotation.
-
Save for Starhunt weekends — rates historically increase by 50% during special events
-
Skip banners with weak featured units — the 7-star pool dilutes your odds of pulling something useful
-
Wait for new unit releases — the first 24 hours of a new banner often have boosted rates
-
Never summon below 500 gems — you want at least 10 pulls to trigger the astd 5 star guarantee
The astd pity system rewards this kind of discipline because your soft pity counter carries forward regardless of which banner you pull on. That means skipping a weak rotation does not reset your progress toward the hard pity threshold — you simply bank those pulls for a better opportunity.
The 5-Star Guarantee Explained in Detail
The astd 5 star guarantee is the most misunderstood mechanic in the astd gacha system, so let's clarify exactly how it works. Every multi-summon (10 pulls at once) guarantees at least one 5-star unit, but the guarantee does not apply to individual pulls. This means spending 500 gems on a single 10-pull is always better than spending 50 gems ten times, because the multi-summon triggers the guarantee while single pulls do not.
| Pull Method | Guaranteed 5-Star? | Effective 5-Star Rate | Gem Cost |
|---|---|---|---|
| Single Pull | No | 10% per pull | 50 Gems |
| 10-Pull | Yes | 100% at least one | 500 Gems |
| 30-Pull (if available) | Yes, plus bonus | 100% + boosted odds | 1,500 Gems |
The all star tower defense pity system also grants bonus rewards for larger multi-summons. According to player reports, completing a 30-pull on the Starhunt banner grants an additional guaranteed 6-star unit, which makes it the most efficient way to spend gems if you have the reserves. The astd 5 star guarantee also applies to the free daily summon, though the free pull does not count toward your pity counter — a detail that confuses many players.
How Pity Carries Across Banners
One of the most valuable features of the astd pity system is that your pull counter persists across banners of the same type. If you spend 60 pulls on the current Gold Summon rotation and the featured unit changes, your progress toward the hard pity threshold remains intact. This means you can build up pity on a banner with a weak featured unit and then cash it in when a strong unit rotates in.
-
Gold Summon pity carries to the next Gold Summon rotation
-
Starhunt pity carries to the next Starhunt rotation
-
Special Event pity does NOT carry — these banners are one-time only
-
Pity resets immediately after you pull the featured 7-star unit
The astd gacha system also tracks your pity separately for each banner type, so you can maintain progress on multiple banners simultaneously. This opens up advanced strategies where you build pity on the Gold Summon while waiting for a strong Starhunt rotation, then switch your spending to match the best available rates.
Maximizing Your Gem Income for Summons
Understanding astd how to get gems for summon is essential because the astd gacha system becomes far more forgiving when you have a steady gem income. Story Mode remains the most reliable source, with each completed stage granting gems based on your performance and difficulty selection. According to community data, a full Story Mode clear on normal difficulty yields roughly 15,000 gems, while hard mode clears can push that number above 25,000.
| Gem Source | Average Yield | Time Investment | Consistency |
|---|---|---|---|
| Story Mode First Clear | 200-500 per stage | 5-10 minutes per stage | One-time per stage |
| Story Mode Replay | 50-150 per run | 5-10 minutes | Repeatable |
| Daily Login Bonus | 100-300 per day | Instant | Daily |
| Code Redemptions | 500-2,000 per code | Instant | Weekly, varies |
| Infinity Tower | 1,000-5,000 per milestone | 15-30 minutes | Repeatable |
The astd best banner to summon becomes less critical when you have multiple income streams feeding your gem reserves. The official All Star Tower Defense Roblox page confirms that the Summon Gate updates hourly, which means you can check the current rotation regularly and only spend when a unit worth chasing appears.

Advanced Gem Farming Strategies
Beyond the basic income sources, experienced players have developed several advanced strategies for maximizing gem income specifically for summoning. The astd gacha system rewards players who maintain a consistent farming routine, since the soft pity counter means every pull brings you closer to the guaranteed 5-star threshold.
-
Farm Story Mode on the highest difficulty you can clear — the gem multiplier scales with difficulty
-
Complete daily quests every single day — the 7-day streak bonus is substantial
-
Save all codes for summoning sessions — redeem 5-10 codes at once before a big pull session
-
Run Infinity Tower on weekends — the tower resets with boosted rewards every Saturday
The astd pity system also creates a natural synergy with gem farming because your pity counter never expires. You can farm gems for weeks, build up a significant reserve, and then spend everything on a single banner rotation with a featured unit you actually want. This approach maximizes the value of the astd 5 star guarantee while minimizing the risk of wasting gems on a banner with a weak featured pool.
Advanced Pulling Strategies for 2026
The astd gacha system in 2026 has evolved beyond simple pull-and-pray mechanics, and players who adapt their strategies to the current meta gain a significant advantage. Based on community testing across the latest updates, the most successful players combine pity tracking with banner timing and resource management to maximize their return on every gem spent. The astd summon rates may be fixed, but your effective odds improve dramatically with the right approach.
The Pity Banking Strategy
The all star tower defense pity system rewards players who think long-term about their summoning habits. Instead of spending gems the moment you have enough for a 10-pull, top players maintain a "pity bank" across multiple banners. Because the astd pity system tracks progress separately for Gold and Starhunt banners, you can build 30-40 pulls of pity on each type simultaneously, then wait for a strong featured unit to cash in.
-
Maintain 2,000+ gem reserves at all times — this gives you four 10-pulls for emergency banner drops
-
Track your pity counter manually — the game does not display your exact progress, so keep a spreadsheet
-
Coordinate pulls with new unit releases — the first hour of a new banner often has the best rates
-
Never pull on the last hour of a banner — wait for the next rotation if the featured unit is weak
The astd best banner to summon changes based on your roster needs, but the pity banking strategy works across all banner types. For a complete breakdown of which units are worth chasing, our summon guide for 2026 covers the current meta in detail.
Understanding Rate-Up Mechanics
The astd gacha system uses a rate-up mechanic that many players overlook. When a unit is featured on a banner, its individual pull rate increases significantly, even though the overall rarity rates remain the same. This means pulling on the correct banner can effectively double or triple your chances of getting a specific unit compared to pulling on a banner where that unit is not featured.
| Featured Unit | Standard Rate | Rate-Up Rate | Effective Increase |
|---|---|---|---|
| 5-Star Featured | 0.5% | 2% | 4x |
| 6-Star Featured | 0.3% | 1.5% | 5x |
| 7-Star Featured | 0.1% | 0.8% | 8x |
The astd pity system also interacts with rate-up mechanics in a favorable way. When you hit the hard pity threshold on a banner with a featured unit, you are guaranteed to receive that specific unit rather than a random unit of the same rarity. This makes the astd 5 star guarantee significantly more valuable on banners with strong featured units, since you know exactly what you are getting when the guarantee triggers.
Common Summoning Mistakes to Avoid
Even experienced players make costly errors in the astd gacha system, and these mistakes can set your progression back by weeks. According to community reports on the official All Star Tower Defense Roblox page, the most common mistakes stem from a misunderstanding of how the astd pity system works or from impulsive spending habits that ignore the astd summon rates.
-
Spending gems on single pulls — you lose the astd 5 star guarantee and effectively waste gems
-
Pulling on every banner rotation — the hourly rotation is designed to tempt you into spending
-
Ignoring pity tracking — without knowing your progress, you cannot plan your spending
-
Skipping free daily summons — even though they do not count toward pity, they still give free units
-
Redeeming all codes immediately — save codes for when you actually need gems for a specific banner
The astd gacha system is designed to reward patience and punish impulsiveness. Every gem you spend on a banner without a strong featured unit is a gem you cannot spend on a future banner with a meta-defining 7-star. The all star tower defense pity counter is your best friend if you track it properly, but it becomes a trap if you let it reset by pulling on the wrong banners.
How to Track Your Pity Progress
Since the game does not display your exact pity counter, you need to track it manually to make informed decisions. The astd pity system resets when you pull the featured 7-star unit, so your counter should reflect your pulls since your last featured 7-star pull. Community tools and spreadsheets have become popular for this purpose, and many top players maintain detailed records of every summon session.
-
Record every 10-pull you complete — note the banner type and the featured unit
-
Track your last featured 7-star pull — this resets your pity counter
-
Calculate your current pity percentage — divide your pulls since last featured by 100
-
Set spending thresholds — decide in advance how many pulls you are willing to commit
The astd 5 star guarantee also resets after every 10-pull, so you do not need to track that separately. However, the soft pity for 6-star and 7-star units operates on a separate hidden counter that only resets when you pull a unit of that rarity. This means your 7-star odds continue climbing even after you trigger the astd 5 star guarantee, which is why multi-pulls remain valuable even when you are not close to the hard pity threshold.
