"Set the Inferno Tower's Dark Elixir fueled flame to build up unbelievable damage to single targets, or to constantly roast multiple targets at once."
The Inferno Tower is a defensive building unlocked at Town Hall level 10, that shoots a stream of flame that burn through even the thickest armor. It can be set to single-target or multi-target.
In single-target mode, the Inferno Tower causes progressive damage to a single-target. The longer the tower stays focused on the same target, the more damage it deals. Its damage is low when it has newly locked on to a troop, but its flame heats up after a short period of time, dealing massive damage and making it most effective against very high-health troops. However, in this mode, the Inferno Tower can be overwhelmed by large groups of weaker units, such as Archers.
In multi-target mode, the Inferno Tower causes constant damage to several targets simultaneously. This makes it ideal against swarms of low-health troops but is much less effective on higher-health troops.
Similar to the X-Bow, the Inferno Tower must be reloaded periodically. This is done for free automatically whenever the player logs in. However, if the Inferno Tower continues firing its ammunition without reloading, it will eventually run out of ammo and not attack.
The Inferno Tower doesn't have a favorite target, nor does it deal more damage to any particular troop. However, in single-target mode, it deals more damage on average to troops with higher hitpoints, due to its progressive DPS.
The Inferno Tower in single-target mode is weak against large numbers of low-health troops. Make sure the Inferno Tower is within range of a Mortar, Wizard Tower, and/or Bomb Tower so that it is adequately defended.
This defensive structure, when set in single-target mode, is tailor-made to destroy high hitpoint troops, such as Dragons, P.E.K.K.As, and Golems. As such, it is a perfect complement to a Wizard Tower, which is very effective against large numbers of weaker troops but struggles against those with high health pools. Positioning these two structures close to each other can substantially improve the survivability of both structures (and the rest of your base).
You can put a Scattershot near the single-target Inferno Tower so that the Inferno Tower can pick off a tank or a hero while the Scattershot will just destroy swarms of low health units at once.
The multiple-target mode can be used to easily overwhelm groups of lower-health troops.
You can place it near storages to help stop Goblins from severely damaging them.
If you choose to place it outside the core of your base, placing it in a range of the outer layer Walls can stop Wall Breakers from breaking them.
It can also prove effective against Balloons, since Lava Hounds cannot fully tank for a multi-targeting Inferno Tower unless five (or six) of them are used at once.
Keep Inferno Towers separated from other important defenses, such as each other and the Eagle Artillery. If they are placed too close, a single Freeze Spell could freeze them all!
As each mode possesses a different advantage, it is advisable to place them in range of each other.
Use the fact that they are 2x2 to hide them in pockets or smaller islands. Try your best to make them harder to reach.
If you have a large clan name on your Clan Castle, you can put it near the Inferno Tower so it will block the Inferno Tower's mode.
Putting a Tornado Trap inside the range of a single-targeting Inferno Tower can suck high-health troops such as P.E.K.K.As or Dragons can let the Inferno Tower destroy them as the troops can't move.
This structure (especially in single-target mode) wreaks havoc with the most common offensive strategies where heavy units go in first to distract defenses with light units following behind them. Letting your heavy troops get in range of it when it is set to single-target spells certain doom for them, even high-level heroes.
You can use Freeze Spells to stop a single-target Inferno Tower from piling up massive damage to a high-health troop. Doing so will not only stop the flames of the tower, but also reset its damage progression so it'll have to build up damage again. If the Archer Queen is being targeted by a single-target Inferno Tower, using her Royal Cloak ability works equally well, as the tower will no longer be able to target the Queen when she's invisible.
Small troops are stronger against the Inferno Tower in single-target mode, as its sluggish retargeting time makes it very weak to swarms. Even Skeletons can pose a threat to it. Golems and Lava Hounds get destroyed in seconds in this mode, but if you surround it with small troops such as Archers and Barbarians it can be defeated very quickly. In single-target mode it can only target one unit at a time, so spreading out the attacking units is not an issue (unless a Wizard Tower, Bomb Tower, or Mortar is nearby).
You can tell if an Inferno Tower is in single or multiple target mode by looking at its top. If it has flames coming out of one large circular hole, it's in single-target mode; if it has multiple small pentagonal holes, it's in multiple-target mode.
Players can deliberately join a clan with a long name and put one Inferno Tower to the left of the Clan Castle to use the clan name to mask the mode of the Inferno Tower.
The visual difference between a loaded and empty Inferno Tower is very obvious. A loaded-tower glows brightly with lava and flame, while an empty one is unlit.
It takes 3 maxed Lightning Spells to take down an initial level Inferno Tower. Bringing a pair of this combination can take out both Inferno Towers against Town Hall 10s.
The Grand Warden's Eternal Tome can protect a tank troop from being severely damaged by a single-target Inferno Tower. However, the ability does not reset the Inferno Tower's damage unless the troop leaves the Inferno Tower's range or if the player drops Lightning Spells or Freeze Spells at the Inferno Towers.
Using a Healing Spell can effectively negate damage done by a multi-targeting Inferno Tower, however, a single-targeting one will quickly outpace the spell's pulse rate and healing capability.
Like the X-Bow, Giants, Balloons, and Golems will still attack an empty Inferno Tower. If it's empty it will be dark and will have no fire lighting it up.
Inferno Towers undergo significant visual changes at all levels.
When initially constructed, the Inferno Tower consists of a tall, narrow tower of rocks straddling a glowing pool of lava. At the top of the Inferno Tower is a circular focusing lens, and a rectangular-shaped Dark Elixir reservoir is mounted on one side. A pool of lava flows at the bottom.
At level 2, huge red flames are emitted from the focusing lens on the top of the tower, and the prominent sections of rock from the first level become gilded with a red overlay. The rock holding the lens becomes gold and the lens themselves become red and the fire overwhelms the ring.
At level 3, the part extending the prominent section each gain a plate with golden spikes. The base structural supports also become thicker and gain gold-colored spikes.
At level 4, the golden rock holding the lens gains another thin layer. Each corner plate gets a golden chain connecting the top of the tower to the base. The inner part of the spiked plate becomes red. The spikes on the plates and the supports move to the side to make space for the chain. The structural supports become even bigger and curves a bit. The golden rocks surrounding the lava pool is covered with a layer rough light-colored stone.
At level 5, around the lens, the rock glows orange, presumably it is heated by the lava. The spiked plates at the top of the tower change to white stone, and the inner part become grey. A circle of smooth stone blocks inserted into the ground appears between the structural support on the base.
At level 6, the heated area of the rock now becomes another lava pool which flows down the plates, it replaces the chains connect the plates and the structural supports. The plates and the golden rock are now replaced with black metal, with the plate losing the spikes and have two steps and the metal still has some golden details. The last bit of golden rocks on the bottom is now covered by an electric coil that have a forked wire connects to the top, presumably powering the pump for the lava to flow back up. The layer of rough light-colored stone on the base is also replaced by the black metal. Smooths stone blocks reinforcement from the structural supports are removed and the supports are replaced with the black metal, hollowed for catching the flowing lava.
At level 7, the black metal and golden details around the top is now ice blue with two black pieces covering the bottom except for the corners. The plates has with navy blue spikes covering it and inner part become purple, the small step is now raised up to the higher part and becoming flush with the inner dark purple part. The upper half of the pillar replaces the wire with segments that glow like lava, it has three vertical segments and two sets of them can be seen, with a ring of blue metal under them. The black metal on the black rock is replaced ice blue metal. The structural supports have navy blue spikes. The reinforcement is more rock-like, slightly bigger, and the middle part being bigger and darker then the other two on the side.
At level 8, the light blue metal between the metal plates are now green, covered in two steps of purplish-black rock and black metal on the side respectively. The black metal plates are replaced with the purplish-black rocks and merge with the inner dark purple part, and the spikes are replaced with gold lining. The pillar lava segments and ring of ice blue metal are replaced by three rings of gold pieces separated by the original prominent part of the pillar that connects to the structural supports. The light blue metal on the black rock is replaced with gold lining, under it at the base, the rock is glowing like lava. The structural supports are no longer slanted, with a fan-like prism having green metal in the inner part and the purplish-black rock on the outer part. The reinforcement is now replaced with a single purplish-black rock with the gold lining pattern.
