Anti-2-Star vs Anti-3-Star Bases in Ranked Battles

Why your destruction average can mislead you

A TH17 player in Electro League asked r/ClashOfClans why their average defensive destruction sat above 90% while most of the league was at 70 to 80%. The replies split into two camps. Some said the layout was simply weak, under-levelled and easy to funnel, and that a TH17 in Electro is mostly attacked by TH18 armies. Others pointed out something more useful: the base was an anti-2-star design. Those layouts aim for one of two outcomes, a high-percentage one star or a triple, and almost never give up a two star. A player running a similar homemade base in Electro 32 shared their week: ten defenses, four triples, six one-stars mostly above 88%, and 160 defensive trophies, which they considered a good result.

To understand why that can be good, you need the trophy rules.

How defensive trophies are split

According to the Clash of Clans Wiki, each Ranked attack is worth up to 40 trophies. The attacker earns trophies based on stars and damage, and the defender earns 40 minus whatever the attacker got. The one exception is a zero-star defense, which always gives the defender the full 40, even if the attacker scored a few trophies for damage.

For the attacker, a three star is worth all 40. A two star is worth 16 at 50% damage plus one trophy for every 3% above that, reaching 32 at 98%. A one star is worth 5 at 1% damage, rising by one for every 9%, up to 15 at 91%. A zero star gives the attacker at most 4. Turned around, these are the defender's numbers using the wiki's own examples:

• Three star: 0 trophies for you.
• 98% two star: 8 trophies.
• 73% two star: 17 trophies.
• 50% two star: 24 trophies.
• 91% one star: 25 trophies.
• 1% one star: 35 trophies.
• Zero star: 40 trophies.

What the numbers say about base types

The key line is the 91% one star. It gives the defender 25 trophies, slightly more than a 50% two star and three times more than a 98% two star. In other words, once an attacker has two stars, every extra percent of damage eats into your score, while a one star is worth a lot regardless of how much of the base was destroyed. That is the logic behind anti-2-star bases: put the Town Hall where it is hard to reach, accept that the outside will be flattened, and collect around 25 trophies every time the Town Hall survives.

Anti-3-star bases make the opposite bet. They assume a competent attacker will get two stars and try to stop the third, ideally leaving the attack stuck in the core with a time fail. A 98% two star only earns you 8, so these bases pay off when the failures are messy, with lower percentages, or when they deny triples that an anti-2-star layout would give up.

Neither is better in general. The value depends on who attacks you. Against weaker attackers, an anti-2-star base turns many attacks into high-percentage one stars. Against strong attackers who can reach the Town Hall reliably, it gives up triples and zero trophies. Commenters in higher leagues said exactly this about popular trick layouts: good attackers will triple them, while weaker ones get caught for a one star instead of the usual two.

Choosing for your league

The number of attacks you take changes with league. The wiki lists 12 Ranked battles a week in Titan, 14 in Dragon, 18 in Electro, 24 in Legend III and 30 in Legend II. The more defenses you take, the less one lucky or unlucky result decides your week, and the more the base's average outcome matters.

Players reported a few patterns worth considering:

• Below Electro, many attackers struggle to path into a well-hidden Town Hall. Several players said anti-2-star style bases and double Invisibility Tower layouts earned a lot of defensive trophies there.
• In Electro and Legend, more attackers know these layouts. One player in higher Legend leagues described double Invisibility bases as easy to cheese with a Giant Arrow to trigger the towers and a clean funnel.
• A layout that relies on a Town Hall weapon or Guardian works differently at TH17 and TH18. Players blamed using a TH18-style layout on a TH17 base for constant 90%+ defenses.
• Under-levelled defenses push every base type toward triples. Several replies pointed to rushed splash defenses before blaming the layout.

What a base cannot fix

Two Ranked rules limit what any layout can do. First, the layout is snapshotted at the start of the weekly season and stays locked, so you cannot react mid-week. Second, your attacks still count for more of your score: perfect attacking weeks can earn the full 40 per attack, while even a great base averages well under that on defense.

The wiki also lists the tiebreakers when players finish with the same trophies: highest average destruction per attack first, then lowest average destruction per defense, then shortest average attack duration. That is the one place where an anti-2-star base's high destruction average can hurt you.

Missing defenses do not hurt. If you take fewer defenses than your league allows, each missing one is credited at the average of the defenses you did take. One Reddit guide to the trophy rules spelled this out after players noticed their final leaderboard position changing once the week was processed.

How to tell which type you are running

Look at a week of replays. If almost every result is either a triple or a high one star, you are running an anti-2-star base, whatever the label said. If most results are two stars and the triples come late in the timer, you have an anti-3-star base. Then compare your defensive trophies to the players around you rather than your destruction average, because the trophy split, not the percentage, decides promotion.
