1. Clash of Clans is great, but what do you do when upgrades start getting expensive? FARM! Waiting for the resources you need can take days in the later stages of the game. This is where farming comes in. Farming is the practice of deliberately lowering your level so that you can attack weaker players and steal the resources you need.this works as you can only attack players in your trophy range. See Step 1 below to learn how to farm effectively and get those upgrades you need.
Preparing to Farm
2. Configure your town. Before you start farming, you will want to ensure that your town is set up properly to both protect your resources and allow you to lose enough to drop down to the level you want to be at. There are several strategies to keep in mind when designing your town.
Protect your storage's. Since you are farming for resources, you don't want your spoils going to a lucky invader. Place your storage's in the center of your town, surrounded by several walls and various defensive buildings.
Place your Town Hall outside your walls. This may seem like it will hurt, but that's the whole point. It gives you more room in your base for storage's. People will also attack you and give you a free 12 hour shield, which is useful.
Do not put your storage's right next to each other. If you put them together, if the attackers get to your storage's, they have gotten to them all. By spreading them out, you reduce your overall loss of resources.
Place high-level resource collectors inside walls and leave the others outside. Keep checking the game after every 6 to 8 hours and collect the resources from the collectors.
3. Get the "Sweet Victory" achievement. This achievement is awarded after you win a certain number of trophies from multiplayer battles, and gives you almost enough gems to purchase the third Builder's Hut. This is essential for keeping your town upgraded.
4. Get about 1,100-1,200 trophies. This is widely considered to be the ideal range for farming, as it allows you to get significant amounts of resources without coming across enemies who are too powerful.If you have very good troops and a strong base you can climb up to 2000-2500 trophies because there you usually find more loot especially dark elixir.
5. Don't rush to upgrade your Town Hall. Your Town Hall level dictates the amount of loot you can get from raids on other towns. If you attack a Town Hall two levels below yours, you will only receive 50% of the loot, and even less for town hall levels lower than that. However, there is no bonus for attacking town hall levels above yours.
Max out the upgrades for each of your defensive buildings, army buildings, and walls before upgrading your Town Hall.
The best Town Hall level for farming is generally 5-7, but can definitely be applicable at the upper town hall levels as well.
