You have three options:
- To keep all your builders working and use the excess Gold and Elixir that you have remaining, onto walls.
- To keep all your builders working except one idle for upgrading walls.
- To ignore all other upgrades and just focus on walls.
These are 3 ways you can upgrade your walls, depending on how you want to play the game. Everyone has their own way on playing the game and there’s no right way. So I’m going to give you guys the advantages and disadvantage of these three options.
For the first one, which is “to keep all your builders working and use the excess Gold and Elixir that you have remaining, onto walls.“ This is the method that I used to farm my walls 90% of the time and is in my opinion the best way to progress in this game if you want a maxed out base quickly. Simply farm and keep your builders busy and even if you have all your builders upgrading your buildings, then you should continue to farm as much as you can until you have full storages. So then once one of your buildings is complete, let’s say your Cannon completed its upgrade and costs 2 million Gold for the next upgrade. Then first use all your excess Gold and Elixir on upgrading walls, but save 2 million Gold to then upgrade your Cannon. This way you will progress the fastest by upgrading all your defenses and walls at the same time by keeping all your builders busy. The only disadvantage is that if you have full storages, you’re going to get hit hard on defense.
For the second option, which is “to keep all your builders working except one idle for upgrading walls.” This is what I did when I was really focused on upgrading my walls quickly. It’s actually what I did when I completed all my level 10 walls in 5 weeks. There’s a very big advantage to keeping one of your builders idle. That is, you are able to freely dump all the Gold and Elixir you’ve stolen during your farming session onto your walls and therefore attackers will have nothing to steal from you on defense. Another big advantage of having an idle builder is that you will be able to upgrade your walls quicker because you won’t be restricted by full storages or incur any losses through defense. I actually find this to be an exploit to the system because of that ability to freely dump your resources on walls, which makes your defenses pointless. If you have no resources, then there’s no point in having high level defenses as there’s nothing to protect. The disadvantage of having an idle builder is that it will slow your progression. For example, if you have a total of 5 builders and are keeping 1 of them idle for walls, then your overall progression will be slowed by 20%. But even at this cost, I believe this to be a very smart way of playing the game.
For the third option, which is “to ignore all other upgrades and just focus on walls.” I really don’t recommend doing this because you’re going to have really high level walls, but your defenses will suffer. So that’s the major disadvantage to this method. Not only that, I value high level Heroes to be way more valuable in this game than anything else. So you really shouldn’t ignore upgrading your Heroes as they will make the biggest difference in the game. High level walls don’t really make much of an impact.
