Spell Factory7

"The Spell Factory is home to veteran Wizards who are better suited to creating magical weapons than front-line combat. Use their powerful Attack Spells to turn the tide of a battle in your favor!"

  • The Spell Factory is an army building that allows the player to create spells. There are currently eight permanently in-game Elixir Spells: the Lightning Spell, Healing Spell, Rage Spell, Jump Spell, Freeze Spell, Clone Spell, Invisibility Spell and Recall Spell. There was one limited edition holiday-themed spell called the Santa's Surprise that was released around Christmas 2012, and one limited edition birthday-themed spell called the Birthday Boom. The Spell Factory is unlocked at Town Hall 5.
  • The Spell Factory takes up a 3x3 space.
  • The spells themselves can be used in battle by selecting a previously created spell and clicking on the enemy's village. The spell can then be placed anywhere, bypassing Walls or buildings, and it cannot be destroyed by any defenses.
  • Like troops, while multiple instances of a single spell could be created (up to the maximum allowed by the spell storage capacity of the Spell Factory and Dark Spell Factory combined), each spell instance can only be used once. Once you have used a spell, you must create it again in order to use it in your next battle.
    • Additional spells can also be queued in the Spell Factory in the same way additional troops can be queued in the Barracks or Dark Barracks.
    • The Spell Factory brews spells at the rate of three minutes per housing space (so for example, if a spell takes 2 housing space, then the spell takes 6 minutes to brew). However, because the brewing queue of the Spell Factory is shared with that of the Dark Spell Factory, Elixir spells and Dark Elixir spells cannot be brewed at the same time.
  • You will not lose your spells if your Spell Factory is destroyed during the defense of your village, nor will its destruction disrupt or pause spell creation in any way.
  • If you upgrade the Spell Factory, it can continue brewing spells, but at half the normal rate (i.e. six minutes per housing space). This should be taken into consideration when upgrading, as spell production may not be able to keep up with troop training.
  • You can speed up the creation of spell with Gems and there is also an ability to boost spell production for 1 hour. The boost option costs 10 Gems, and will increase the speed of the Spell Factory (as well as the Dark Spell Factory) by a factor of four.
    • Note: The boost timer will continue to count down even if you aren't creating spells, so don't boost your Spell Factory until you are ready to use it.
    • When you click to boost the Spell Factory a clock appears for a few seconds.
  • Players can donate spells to clanmates, provided that their Clan Castles are sufficiently upgraded to receive them.
    • A level 4 or higher Clan Castle is required to hold 1 housing space Elixir spells (Lightning Spell, Freeze Spell and Invisibility Spell).
    • A level 7 or higher Clan Castle is required to hold 2 housing space Elixir spells (Healing Spell, Rage Spell, Jump Spell and Recall Spell).
    • A level 10 or higher Clan Castle is required to hold the 3 housing space Clone Spell.

Upgrade Differences

  • Spell Factories undergo significant visual changes at each level.
    • When initially constructed, the Spell Factory consists of a gray metal cauldron with a valve and hand-wheel at the front. It is supported by a total of eight wooden legs lashed to the edges of the cauldron, and at the rear there is a slingshot-looking structure used to hold the massive stirring spoon while the Spell Factory is in operation.
    • At level 2, the Spell Factory cauldron changes from gray metal to bronze.
    • At level 3, the Spell Factory cauldron changes from bronze to gold. The ropes attaching the legs to the cauldron disappear and are replaced with three golden rails encircling the cauldron.
    • At level 4, the Spell Factory gains spiked metal armor protecting the four corners of the structure, similar to those found on the Gold Storages and Elixir Storages.
    • At level 5, the Spell Factory gains blue hexagons on the protective pads with golden spikes surrounding on each corner.
    • At level 6, the Spell Factory's corners turn into stone slabs in the shape of a pentagon. The slabs are white at the top and dark grey along with being slightly wider at the bottom. On the corners are shield-like objects with it being thinner and darker along the center. There are two spikes along the cut there.
    • At level 7, the Spell Factory's corner pieces now take on a blue and gray appearance topped with an ice-like slab, resembling the theme of Town Hall 13. The spiked cuts are replaced with two slabs on each corner, with a spike on each.
  • When in operation, the Spell being created in the cauldron changes color at each level. Note that this coloring is dependent on the level of Spell Factory only, not on the type of spell being created (it is impossible for anyone other than the owner to determine which spell is being created, except if the Spell Factory is at level 1).
    • At level 1, the spell in the cauldron appears azure blue, resembling the Lightning Spell.
    • At level 2, the spell in the cauldron appears golden, resembling the Healing Spell.
    • At level 3, the spell in the cauldron appears deep purple, resembling the Rage Spell.
    • At level 4, the spell in the cauldron appears green, resembling the Jump Spell.
    • At level 5, the spell in the cauldron appears light blue, resembling the Clone Spell.
    • At level 6, the spell in the cauldron appears dark blue, resembling the Invisibility Spell.
    • At level 7, the spell in the cauldron appears pink, resembling the Recall Spell.

  • The level 4 Spell Factory is currently the only level that can unlock two spells at the same time, namely the Jump Spell and the Freeze Spell.
    • This property is not shared by the Barracks, Dark Barracks, Workshop or the Dark Spell Factory, outside of temporary troop events, where certain levels of Barracks enable training of the temporary troop. Although Super Troops require the same Barracks/Dark Barracks level as their base troop, none of them (as of December 2021) can be unlocked with a level 1 troop.
    • When the December 2015 update made this the case, up until the introduction of the Clone Spell in mid-2016, the level 5 Spell Factory was also the only level of any army-training building that did not unlock any new units.
  • If a spell has been brewed while the player is at the Builder Base, the Spell Factory, as well as the Dark Spell Factory, will still play the "spell brewed" sound when complete.
    • However, it won't create a sound at the Builder Base if the Training Potion is used.
  • Although the Clone Spell is cyan and the Invisibility Spell is mint green, brewing any spells from a level 5 and 6 Spell Factory creates a dark blue mixture from a cauldron that represents Clone Spell and Invisibility Spell respectively.
  • Despite being "home to veteran wizards", there are no spell making Wizards to be seen. However, the Spell Factory and the Wizard are unlocked at the same Town Hall level (5).
  • Since there is no spell counterpart of the Army Camp which can hold spells, the Spell Factories takes the role of both creating and holding spells: the Spell Factory determines the main part of spell capacity, while the Dark Spell Factory increases the capacity by 1. For example, you'll have to upgrade the Spell Factory to level 5 (rather than upgrading the Dark Spell Factory) in order to hold 11 Dark Elixir spells.
  • Despite not being available as a card in Clash Royale, the Spell Factory can be seen in the Spell Valley arena as a decoration.
  • Elixir spells' brewing times have been decreased multiple times.
  • In 2013, 2014, 2015, and 2016 October maintenance breaks, players were able to boost their Spell Factory for one Gem only. The 2015 October maintenance break was the first time that this applies to the Dark Spell Factory as well, which wasn't present in previous years.
  • The pre-release design of the level 6 Spell Factory, which depicted a Town Hall 13 theme, was later reused as the design for the level 7 Spell Factory.
