Defence
Defence is a vital part of clash of clans. Here at COC wiki advise users to upgrade most defences before others things.
Cannon
The cannon is the first defence weapon you will receive in Clash of Clans. We advise you to upgrade the cannon as much as possible.
Archer Tower
The archer tower is a very handing defensive weapon because to can easily take down most flying troops such as dragons and balloons etc.
Mortar
Mortars are one of the most effective weapons in the game because there so powerful. It is recommended that the mortar or mortars are placed in the centre of your base well protected by walls, cannons etc. The mortar is so powerful because it blasts huge bombs were every the opponent is attacking and mostly kills all the troops I one hit. The more you upgrade your mortars the more damage they create.
Air Defence
The air defence weapon is also very important because what this weapon does is take down any air target in less than 5 shots! this defensive weapon comes in handing when your attacker is in love with dragons!
Wizard Tower
Wizard Towers are very expensive towers that are guarded by very powerful wizards. The bad thing about them is that they can be destroyed quite easily, so you need them to be well protected to get the full effect of what they can do.
Hidden Tesla
A hidden tesla is a very powerful electrical tower that hides in the ground.This weapon is very handy but is also very fragile so it doesn't take much to destroy it.
X-Bow
X- Bows are extremely powerful and only the elite can purchase them. They help protect your base and are difficult to destroy. The downfall of an x- bow is you need to refill the arrows with elixir.
Inferno Tower
The Inferno Tower is the best of them all! The tower shoots liquid fires can burn through any armour. If your opponent has one of these bad boys... i would be afraid!
