City

For german-language, any kind of language, please use: copie and past and than: google-translate in google. Enjoy! The city contains different buildings, each one offering a unique feature. It has 6 buildings to use, 4 are upgradable.

Library
This building lets you upgrade certain buffs based on how much experience you gain from battles. There are 1, 2, and 3-star research categories, which are the three tiers of buffs. The second tier is unlocked after tower level 70 and the third tier after tower level 150. Once you rush to wave level 150 in-game (and I mean rush, as you should be speeding through the Battle Pass at the beginning of the game), there is a certain order recommended to leveling your first buffs:


 * 1) Experience for the kill (1-star)
 * 2) Increases gold that is mined from seized castles (2-star)
 * 3) * This gives a lot more gold than #3 early and mid-game.
 * 4) Gold for the kill (1-star)
 * 5) Lowers the time necessary to reload active abilities (1-star)
 * 6) Increases units’ attack speed (2-star)
 * 7) Increases critical hit damage (1-star)
 * 8) Increases units’ range of attack (3-star)
 * 9) * This is important everywhere except castles.
 * 10) Increases damage from active skills (3-star)
 * 11) Increases tower strength (1-star)

Note: After your ninth research, you can freely choose which order of research to put your experience into, but a very slight recommendation would be to go for Increases damage caused by all Archers and Increases damage caused by Mages, which are both 3-star buffs. Then go for 2-star ones involving modules, and then 3-star ones involving damage to enemies (goblins, bandits, horde, and undead). Level all summoned creatures’ buffs next and then turrets’ buffs. Completely skip on Increases damage caused by Throwers.

If you have already gone in an incorrect order, don't spend the gems to reset, just try to follow this order from now on. You'll fill all of the buffs eventually.

Gold Mine
The gold mine produces gold every 5 seconds, the amount of gold depends on the level. The gold will automatically go into the storage.

Time to Payback calculates how long it will take for you to receive the gold back that you purchased for a single upgrade. Note: If you always use the 2x gold option, these times will be cut in half.

Storage
The storage contains the gold mined every 5 seconds. The level of your storage defines the capacity of storage, when it is full the gold mine will not produce any extra gold. You can collect the gold at any time, while collecting it above 30% offers a chance to double the gold.

Forge
The forge is used to create new artifact for your statue. The forge can create different level gear as well as different tiers and types, with each tier adding one more ability type. Creating a new artifact requires gold but also crafting resources. It is recommended NOT to craft anything until Forge level 10.

Statue
The statue is where you decide which artifacts you want to use and receive bonuses from. You can only equip one of each type of artifact at a time. You can also scrap or "dissipate" your artifacts for a small gold price to get back some materials if you didn't like the artifact you got, or if you had an extra.

There is 5 different slots to equip:
 * Right arm weapon
 * Left arm weapon
 * Helmet
 * Medallion
 * Breastplate

Artifacts can be acquired by defeating castles/bosses on the map, defeating islands, opening the portal chest, events, artifact fair purchases, or crafted in the forge.

Training Field
The level of the training field sets a cap on the level of your units. It also is necessary for upgrading them to the next level of their ability, during which time the unit becomes unavailable to use in gameplay.

The time of unavailability depends on the level of the upgrade.
