The June Update Just Quietly Changed TH18 Base Design

The June 15, 2026 update changed how Fireball, Seeking Shield, and Spiky Ball pick their first target so they now factor in building size instead of aiming at the building's middle point. In plain terms, those equipment pieces stop getting yanked onto a tiny building sitting next to your Town Hall or Eagle. So the old base-building habit of cramming a small decoy building beside a key defense to bait the hit is dead. Isolated Town Halls and isolated key defenses are now the stronger layout, and a lot of popular TH18 templates need a small rework.

Supercell's patch notes describe it as a quality-of-life fix, not a balance change, which is exactly why it's easy to miss. The exact line reads: "Changed equipment's initial target selection so it takes building size into account instead of targeting the building middle point. This reduces the likelihood of targeting the wrong building with Fireball and also affects Seeking Shield and Spiky Ball."

Before the patch, these equipment pieces locked onto whatever building's center point was closest to the cast. That's a math problem, not a smart-targeting problem. A small Tesla or a Bomb Tower wedged right against your Town Hall could have its center point sit fractionally closer to the projectile path, so the equipment hit the small building and the real target shrugged it off. After the patch the game weighs the footprint of the building, so a 4x4 Town Hall or a big Inferno wins that comparison over a 2x2 filler. The hit lands where the attacker meant it to land.

If you want the full rundown of everything else that shipped, the Yeti rework, Hard Mode, the new Builder's Apprentice, I covered that separately in the June 2026 update explainer. This post is only about what it does to your base.

For a while now, a quiet trick floated around higher-level war bases: park a small, low-value building right next to your Town Hall, Eagle Artillery, or a single Inferno, specifically so an attacker's Fireball or Spiky Ball would clip the decoy instead of the thing you cared about. It was never a headline strategy, but base designers who knew about it used it to soak one big equipment hit and force the attacker to spend a second cast.

That trick relied entirely on the center-point targeting that the June update just removed. Now the equipment reads the bigger footprint first, so the decoy gets ignored and the real defense eats the hit anyway. Every base built around "bait the Fireball with a filler building" lost its edge overnight. Worse, those bases are often more vulnerable now, because cramming filler next to a key defense usually meant skimping on spacing and trap coverage elsewhere. You paid a layout cost for a trick that no longer pays out.

If you're running a downloaded war base from before mid-June, it's worth a quick look. Anything with a Bomb, Tesla, or Wizard Tower jammed flush against the Town Hall core was probably built with this in mind.

The honest answer is the boring one: give your Town Hall and your key defenses room to breathe. An isolated Town Hall, one with a small gap of walls or open tiles around it rather than a small building pressed against it, is now strictly better against equipment-heavy attacks, because there's nothing nearby for the projectile to mis-target onto in the first place.

A few practical rules I'm following on my own TH18:

- Don't pad your core with filler. If a small building was only there to bait equipment, pull it out and use that space for a trap or better wall geometry. - Spread your high-value targets. Town Hall, Eagle, and Infernos shouldn't all sit in one tight pocket where a single well-placed Fireball plus Spiky Ball combo can chew through the whole cluster. The targeting fix makes those equipment pieces more reliable for the attacker, so clustering is riskier than it used to be. - Lean on real defensive geometry, not gimmicks. Compartment walls, off-center Town Halls, and well-placed point defenses age a lot better than a trick that one patch can delete.

If you'd rather not rebuild from scratch, grab a fresh, post-patch layout from the Base Drop base finder, you can filter by Town Hall level and base type, and the layouts there already reflect the isolated-core approach instead of the dead decoy meta. It's the fastest way to swap in something that isn't built on a trick that stopped working.

The dominant TH18 attack right now is the Root Rider plus Super Yeti push with a Royal Champion charge cleaning up, and that army leans hard on equipment. The Royal Champion's Seeking Shield and the Fireball/Spiky Ball pressure that comes with these compositions are exactly the equipment the targeting fix touches.

What that means for your defense: those equipment hits are now more accurate against you, so any base that was secretly relying on equipment misfiring onto a decoy is going to feel softer against the meta army. The fix helps the attacker land their burst where they want it. You can't out-trick that anymore, so the counter is structure, pull your Town Hall and Infernos out of one shared pocket, make the Root Rider funnel work for its value, and protect your anti-air so the Yetis can't walk in clean.

For the attack side of the same matchup, I broke down how this army runs in the best TH18 attack strategy guide for war and CWL, and the anti-3-star TH18 war base layout post walks through the spacing that holds up against it. The short version: build for spread and compartments, not for one clever hit-soaking building.

Everything I've said about TH18 applies just as much to TH16 and TH17, maybe more. The decoy-building trick was never TH18-exclusive, it was a habit baked into a lot of war-base templates from the moment Fireball and Spiky Ball became common attacking equipment, and that covers the whole upper end of the game.

If you're sitting at TH16 or TH17, pull up your current war layout and look at your Town Hall, Eagle, and single-target Infernos. Is there a small building, a Tesla, an Air Defense, a Bomb Tower, wedged right up against any of them with no real spacing? If so, that adjacency was probably doing decoy duty whether the original designer intended it or not, and it's no longer helping you. The fix reads building size now, so the big defense eats the hit regardless.

The rebuild advice is identical across these Town Halls: isolate your highest-value buildings, spread them so one equipment combo can't chain through a cluster, and lean on compartment walls instead of bait. The good news is you don't have to figure the spacing out by hand, you can pull current, copy-ready layouts for TH16, TH17, and TH18 from the base finder and skip straight to a base that's already built for the post-patch targeting. It's the lowest-effort way to make sure you're not defending June's meta with a May base.

It does, and it's a nice side benefit. If you run equipment-based attacks, a Spiky Ball Queen walk, a Fireball opener, a Seeking Shield charge, your equipment now lands on the building you're actually aiming at instead of occasionally wandering onto some 2x2 next to it. That's a real consistency bump for farmers and war attackers alike. You'll notice it most on those moments where a Fireball used to "miss" a Town Hall by clipping a storage, that frustration is mostly gone.

So the patch quietly tilts the game toward attackers twice over: their equipment is more reliable, and the old defensive bait that countered it no longer exists. That's the real reason this small bug fix matters for base design, it removed a defensive option without giving defenders anything back. The bases that win now are the ones that never needed the trick.
