The video below demonstrates the strategies recommended in this guide in action. It is worth watching to get a better idea of how to place units and evaluate target bases.
TH7 Clan War Army Composition
The best army composition at Town Hall 7 for War Battles is to use 10 Dragons. If you want to take on mid-range TH8 players, it is useful to have a Dragon in the Clan Castle and to upgrade your Dragons to level 2. Note: Technically a 25+ Hog Rider army will outperform 10 Dragons, but that is an enormous waste of Dark Elixir. It is much easier to get excess Elixir to pump into Dragons as opposed to getting the 900+ DE required to build a 25+ Hog Rider army.
Since Dragons require a level 9 Barracks, it is in your best interest to level up all of your Barracks to level 9 shortly after hitting Town Hall 7. Just upgrade each Barracks one at a time until all are level 9 so that you do not suffer from low production at any point.
The spells and strategies you use depends on whether or not you are attacking a Town Hall 7 player. Town Hall 7 players are much easier to take down with a 10 Dragon army, as players get a third Air Defense upon hitting TH8. Town Hall 8 players can still be 3-star cleared, but not every TH8 player can be cleared. Evaluating bases, good unit placement, upgrading Dragons, and spell choices will determine your ability to 100% clear TH8 players reliably.
Against Town Hall 7 Players
Taking down TH7 players with 10 Dragons is very easy. Players may or may not need spells; you will only need spells if you have level 1 Dragons and the enemy player has maxed out Air Defense towers. If the enemy player has maxed out their Air Defense towers, all you have to do is build 3x LIghtning Spells. Use the three LIghtning Spells on one of the Air Defense towers, destroying it (Lightning Spells do need to be level 3 or higher for this purpose).
With only one Air Defense left, you can place your 10 Dragons practically anywhere on the map and get an easy 100% clear. Place them in the same area of the map, but spread them out a little bit in order to reduce the effects of splash damage.
Against Town Hall 8 Players
Town Hall 8 players can be cleared with 3 Stars by TH7 players using Dragons, but certain conditions need to be met for this to be reliable. FIrst off, it helps significantly if the TH7 player has level 2 Dragons. A Dragon in the Clan Castle is very useful as well, but not necessary. The preferred combination of spells is two Rage Spells and one Healing Spell.
In addition to leveling up Dragons, it helps significantly if the TH8 player does not have maxed out Air Defense towers or has poorly positioned Air Defense towers. Level-wise, if the average level of Air Defense tower is less than 4 (Air Defense towers turn black at level 4, so level 4+ are easy to spot), that is a good sign. If all 3 towers are level 4 or higher, that is a bad sign.
If the towers are either on the edge of the base or clustered together, level of the enemy tower may be irrelevant. Clustered towers are susceptible to a Rage Spell + Healing Spell combination, where a few Dragons can rip down multiple towers while being healed. The video guide embedded earlier in this article demonstrates this in action on one such base with clustered AIr Defense towers.
Placement of Dragons is very important when attacking TH8 players (as opposed to TH7 where it is practically impossible to mess up). First, choose the side of the base you want to attack. it is best to start your attack within range of the most Air Defense towers or near the highest-level tower. Initially, drop two Dragons, about two structures apart on the perimeter of the base where you want to attack. These Dragons likely will not actually participate in the main attack, and instead will travel along the perimeter of the base, picking off external structures. This is intended, as you do not want the bulk of the Dragons to travel along the outside of the base but instead head towards the center. The Barbarian King can aid in this function as well.
As soon as the two initial Dragons take out a few perimeter buildings, drop your remaining 8 Dragons. They should now head towards the center of the base with all the perimeter structures destroyed. Drop a Rage Spell somewhat deep into the center of the enemy’s base; this will speed up the Dragon’s clearing into the enemy’s base and should result in the destruction of at least one Air Defense tower. As the Dragons core towards the Town Hall or a cluster of high health buildings (storages), drop your second Rage Spell. Drop the Healing Spell as needed on low-health Dragons – this will vary on a battle-by-battle basis. Check the video guide for more details on healing spell placement.
With enough practice, you will find the 10 Dragon army can reliably 100% clear many TH8 bases. Many enemy players neglect leveling up their Air Defense towers while having high level walls and other towers. These bases are great for Dragon-based attacks; you will get a large resource reward and your clan will be happy you cleared a tough opponent with 3 stars.
