Town Hall Level 9 Upgrades
In order to reach Town Hall Level 9 in Clash of Clans, you’ll need to spend 3, 000, 000 gold and wait 10 days for the upgrade to be completed. Upon the Builder’s completion of the upgrade, the Town hall will gain an additional 500 hit points and grant access to an additional 9 buildings. This includes 25 new wall sections, an Archer Tower, an Air Defense, a Wizard Tower, a Hidden Tesla, another Giant Bomb, 2 more Seeking Air Mines, and 2 X-Bows.
This upgrade also increases the maximum upgrade level for the Cannons, Archer Towers, Mortars, Air Defenses, Wizard Towers, Hidden Teslas, Bombs, Air Bombs, Seeking Air Mines, Skeleton Traps, Dark Barracks, the Army Camps, the Laboratory, the Spell Factory, and the Clan Castle.
This new Town Hall allows you to purchase an additional Gold Storage and Elixir Storage for unlock, raising your potential maximum amount of resources to 8, 000, 000 for both types. This also allows you to upgrade both your Dark Elixir Drills from level 3 to level 6 to increase the production rate to 100 Dark Elixir per hour and the maximum capacity to 1, 800 Dark Elixir, at a cost of 12, 000, 000 Elixir and 18 days each.
In addition, the Dark Elixir Storage may be upgraded from level 4 to level 6 at a cost of 6, 600, 000 Elixir and 11 days, increasing the hit points to 3, 600 and the storage capacity to 200, 000 Dark Elixir. To increase your troop capacity to 30 troops and your War Loot Capacity to 1, 500, 000 Gold and Elixir and 6, 000 Dark Elixir, you must upgrade your Clan Castle to level 5 at a cost of 5, 000, 000 Gold and 7 days.
Defense
On the side of defense, it is important to upgrade your single-fire turrets early on; however, it is up to the player to decide whether to invest in new defenses or to further upgrade existing defenses. Players can purchase X-Bows at a cost of 3, 000, 000 Gold and 7 days, as these turrets can target both air and ground troops; however, X-Bows must be loaded with Dark Elixir in order for them to actually operate. Players may also purchase an additional Hidden Tesla, as these take up less space than traditional defenses, can target both ground and air troops, and appear invisible when other players scout your base.
The Cannons can be upgraded to level 11 to improve damage per second to 75 and increase the hit points to 970, at a cost of 3, 200, 000 Gold and 5 days each. The Archer Towers can be upgraded to level 11 to improve damage per second to 75 and increase the hit points to 805, at a cost of 4, 500, 000 Gold and 6 days each. Finally, to ensure that your Air Defense can readily deal with Dragon raids, you can upgrade your Air Defense to level 7 at a cost of 4, 320, 000 Gold and 10 days each to increase damage per second to 280 and increase hit points to 1, 110.
Next, players should focus on improving defenses that deal splash damage, along with traps. Mortars can be upgraded to level 7 at a cost of 3, 200, 000 Gold and 7 days, to improve damage per second to 11 and increase the hit points to 700. Wizard Towers can also be upgraded to level 7 at a cost of 5, 360, 000 and 7 days to improve damage per second to 40 and increase the hit points to 840. Traps can also provide important stopping power to thwart raids that would normally be successful. For example, bombs are useful for taking out smaller troops, such as Barbarians, Archers, and Goblins.
Big Bombs are useful for heavier troops like Giants, Golems, and P.E.K.K.A.s. Air Bombs and Seeking Air Mines are useful for a range of aerial troops, from Healers, to Dragons, to Minions. Upgrades to all of these traps increase the damage they cause and their rearm cost. Unique to most other traps, upgrades to the Skeleton Traps increase the number of spawned skeletons, delaying raiding troops from attacking your Town and stealing your resources.
