An Engineered Base is a base specifically built for war, it is sometimes called a defenseless base. The base overwhelmingly promotes offenses over defense. The objective of an Engineered Base is to provide a matchmaking advantage in war.
In war clans are matched on the overall strength of its members. Strength is based on each member’s attacking power (troops, army camp capacity, spells and heroes) and defensive strength (defense buildings, walls, traps and heroes).
Matchmaking will prioritize defensive capabilities in pairing Clans.
Powerful, late-game defenses and troops like Inferno Towers, Eagle
Artillery and Grand Warden will have much greater matchmaking impact. A
full guide to matchmaking can be found above.
As the Clash of Clans algorithm in matchmaking favours defense, many clans build their bases to exploit match-ups in their favour, to do this they favour developing offensive troops and maintain a very low level of defense.
Engineered bases can look very similar to rushed bases. You are advised that an Engineered Base should not be you primary account. Many clans would refuse you clan entry as they appear rushed.
Building them is easy, upgrade your Town Hall to any level and ensure that the defenses are 2 or 3 levels below. These bases should only be considered for those active in war as farming with these bases are troublesome due to their poor defense.I think we all know why we should upgrade these 3 buildings at first. Upgrading our current troops to their new max levels should always be the highest priority. By upgrading 2 Spell Factories, you can bring more and new spells into the attacks, especially very essential for Clan Wars, where just one more Spell can change everything. At Town Hall 8, you can get the Poison Spell, which helps you deal with the Clan troops much easier, and the Earthquake Spell, which helps you finish off most Town Hall 8 war base with the Zapquake Combo.
- Upgrading Heroes to level 5 (TH7/9):
Who doesn’t like new impressive weapon for both farming and Clan Wars? Get the level 5 Queen If you are at TH9 and the level 5 Barbarian King If you are at TH7 as soon as possible.
- Army Camps
The more troops you have, the much stronger your army is. Get them done as soon as possible.
- Clan Castle
Undoubtable,
Clan Castle is the strongest defensive building in Clash of Clans.
Moreover, with high level Clan Castle, you can bring more strong units
for raiding, especially the troops you haven’t owned yet.
- Heroes
After upgrading all those above, I think you should start working on
your Heroes. Because this is a long term job so just do it whenever you
have the opportunity. Lots of players like upgrading Barbarian King
before the Archer Queen
and vice versa because he can take damage and protect the Archer Queen.
Let’s discuss about this late. For now, just upgrade the Hero you like
and follow this guide for upgrading your Heroes effectively.
- Upgrading new Walls
You don’t need to upgrade your walls to their maximum level at the previous Town Hall, but you should upgrade them to a certain level which can’t be destroyed by just 1 Wall Breaker (see more at Wall Breakers Vs. Walls). Mix them up, upgrade your walls when you have loot and also want to keep your Builder free.
- Build new Air Defense and Giant Bombs
Build these new stuffs If you’ve just hit Town Hall 8/9 and upgrade
them to the level of other current ones. With the 3rd Air Defense at
Town Hall 8, you don’t need to worry about Dragon attacks anymore. Giant Bombs are critical at all Town Hall levels for dealing with either Hog Rider attacks or Barch variations.
- Normal buildings
Clash of Clans is not just about attacking and defending, non-defensive buildings also play a role in game.
IMO we should upgrade Dark Elixir Drills at first because the amount of
DE we need it is unlimited. In addition, high level Dark Elixir Drills
have an insane producing speed.
By having them, you can upgrade your troops much easier. While your
Drills are being upgraded, the next building you should upgrade is
Barrack. With new troops, especially at TH7 (Dragons) and TH9 (Lava
Hound), you can have new stronger attack strategies and have lots of
advantages in both - Clan Wars and farming.
After that, you can start working on Storages and other Collectors.
- Traps:
You can either upgrade trap to the level as other ones’ at last or mix
them with the Collectors/Storages, which suits you the best. Upgrade
them when you don’t want to hoard too much loot for a long time.
- Upgrade new defensive buildings
- Upgrade them to the max levels at the previous Town Hall, like other
current defenses. You can do this and upgrade your traps at the same
time. Remember: Just upgrade them to the previous TH max level.
- Maxing defensive buildings and walls
This depends on what loot you focus on. Let’s assume that we are normal players and focus on both 3 resources at the same time.
If you want to get 3 stars from the base which has the same progression as you, you need to be maxed out your troops at first.
Based on the match making system, you should upgrade your walls until
you max out all your War troops. With the same amount of Gold, If you
work on defensive structures before walls, your defensive buildings will
be maxed out before your War troops, for sure. Although all walls cost
much war weight than defenses but you need less time to work on defenses
than walls. If you focus on upgrading your troops at first, you will
always face easier bases than If you focus on defensive building
For the best results in Clan Wars, I recommend this upgrade order:
