Clash of Clans wall upgrade guide (with gold and elixir)
Walls can be upgraded with gold and elixir, and the best use for them is to drain full storages. Upgrading walls over the long term isn't cheap; that's why doing it regularly and automatically is more efficient than waiting for the cost to pile up all at once.
Why are walls hard to upgrade?
Walls are the most numerous structure in the village. Each wall segment has to be upgraded one by one, and in total that means a large amount of resources. It isn't one big expense like upgrading a single building; it's hundreds of small ones. This structure makes wall upgrading both tedious and a test of patience.
On the other hand, walls are the foundation of defense. They steer attacking troops and buy time around your defenses. Neglecting walls weakens even strong defenses. That's why a regular wall plan matters for the village's overall strength.
Gold and elixir: two resources for walls
Walls can be upgraded with gold and elixir. This lets you use your loot in two ways while farming: if you've saved up enough gold, move forward with gold; if your elixir is full, move forward with elixir. Balancing spending by looking at which is more plentiful keeps your storages from overflowing. Costs by level and which resource is used from which level can change with the game version; for current values, the best thing is to check the Walls wiki page.
When should you spend on walls?
When your gold and elixir storages are close to full, it's the right time to spend on walls. A full storage causes loot to be wasted; spending prevents that. But priority order matters too: hero and defense upgrades are often considered more urgent than walls. A practical approach: start the critical upgrades first, then direct what's left to walls.
| Status | Recommended move |
|---|---|
| Storage about to fill, no free builder | Reserve the next builder that frees up for walls |
| Storage full, no critical upgrade | Upgrade walls with gold or elixir |
| A critical upgrade is waiting | Start that first, give the remaining resources to walls |
| Resources are low | Hold off on walls, keep farming |
Builder management
Wall upgrades may not need a builder, or the time may be short; but the real question is whether your builders are busy. If long building upgrades keep all builders busy, there is nobody left to put on walls. That's why dedicating one builder to walls is a smart strategy: while the others work on big upgrades, one keeps walls moving all the time.
Manual upgrading vs. automatic wall mode
Upgrading walls by hand means opening the menu and selecting them one by one every time. Automatic mode does that for you.
| Criterion | Manual | Automatic wall mode |
|---|---|---|
| Time | Separate attention for each upgrade | Keeps going when you're away |
| Resource use | Can be put off until the storage is full | Spends a full storage on walls right away |
| Resource type | You choose | Uses gold and elixir together |
| Builder | You reserve one by hand | Wall mode reserves a builder for walls |
cocbot's wall mode does exactly this: with gold and elixir, it spends full storages on walls and reserves one builder for walls. It verifies the spending; that is, it checks that the upgrade has really started. That way the surplus resources from farming turn into your village's defense.
Practical tips for a wall plan
- Start the critical upgrades first, direct the leftover resources to walls.
- Consider dedicating one builder to walls permanently.
- Use gold and elixir in balance so neither one overflows.
- Don't expect to finish walls overnight; steady progress pays off.

How do walls and your defense layout affect each other?
It would be wrong to treat wall upgrades as a goal on their own. Walls are a shell around your defensive buildings and storages; the strength of the shell only means something relative to the value of what's inside. If your village's critical structures are still at a low level, it's often smarter to put resources into them first. On the other hand, in periods when resources are plentiful, that is, when storages are full, spending on walls both strengthens defense and prevents loot from going to waste.
The layout of the walls matters too. The more orderly the compartments, the longer the path for attacking troops. But the upgrade order depends on resources and time, regardless of layout. So set up the layout first, then raise the level as resources become available.
How do you make a weekly wall plan?
A regular plan is far more efficient than upgrading walls at random times. A simple approach: during the week, first assign the resources coming in from farming to critical upgrades, and when a storage is getting close to full, move the remainder to walls. A bit of progress each day makes a visible difference by the end of the week. Once you dedicate a builder to walls permanently, this progress continues without your attention.
| Plan element | Purpose | Practical note |
|---|---|---|
| Critical upgrades | Moving heroes and defenses forward | These are started first |
| Builder reserved for walls | Uninterrupted wall progress | The other builders handle long jobs |
| Storage tracking | Preventing overflowing resources | A full storage is directed to walls |
| Resource balance | Using gold and elixir together | Go with whichever is more plentiful |
Common mistakes when upgrading walls
- Piling all your resources into walls at once: It delays critical upgrades.
- Neglecting walls entirely: Full storages go to waste and defense stays weak.
- Relying on one resource: One of gold or elixir overflows while the other goes unused.
- Keeping builders always busy: There's nobody left to put on walls.
- Not checking the spending: Moving on without seeing whether the upgrade actually started.
The last point matters: a tap sometimes fails to start the upgrade. That's why cocbot verifies the spending; it checks that the resource dropped and the upgrade started. That way an action that fails silently doesn't go unnoticed.

Summary: a short roadmap for walls
Walls can be upgraded with gold and elixir; their most natural use is draining a full storage. Start the critical upgrades such as heroes and defenses first, and give the remaining resources to walls. Dedicating a builder to walls keeps progress uninterrupted. Use gold and elixir in balance; don't leave one waiting while the other overflows. Check that the spending really started, because a tap that fails silently can go unnoticed for days.
Wall work is long-haul and tedious by nature. That's why doing it regularly and automatically preserves progress even when your attention wanders. With a little patience, your village's shell gets noticeably stronger within weeks. All you need to do is think of farming and spending as parts of the same loop.
Frequently asked questions
Are walls upgraded with gold and elixir?
Yes, walls can be upgraded with gold and elixir. Which resource is used at which level, and the costs, can change with the game version.
Does it make sense to spend full storages on walls?
Generally yes. A full storage causes new loot to be wasted. Once the critical upgrades have started, putting the leftover resources into walls is an efficient approach.
Do I need to dedicate a builder to walls?
It isn't mandatory but it's practical. While the other builders are busy with long upgrades, one keeps walls moving all the time.
How does automatic wall upgrading work?
cocbot's wall mode spends full storages of gold and elixir on walls, reserves one builder for walls and verifies that the spending has started.
