Currency

These are resources obtainable throughout the Art of Conquest. Proper management of these resources is  vital  for player progression and survival in the game.

Gold
Gold is used to train troops (there are some exceptions as lich). It is also used for shop purchases along with Linari. Gold is often used for research. Gold is arguably the most important and most used resource in the game.

Elixir
Elixir is used to produce some lich troops, as well as research, but not much else. Most people will end up with an abundance of elixir during late game. If you are playing Rakan, elixir is used for Ale abilities

Lumber
Lumber is used mostly to upgrade buildings. It is also used for research. This resource becomes very important late game.

Blood Diamond
Blood Diamonds are used to train silver and gold troops. It is usually used less compared to Mithril and Crystal.

Mithril
Mithril is used to train silver and gold troops. It is used more than Crystal and Blood Diamond.

Crystal
Crystal is used to train silver and gold troops. It is used somewhere in the middle between Blood Diamond and Mithril.

Adamantium
Used in the void to buy market items and unlock void heroes.

Crafting Stone
Used to buy items at item shops (Mafa's Item Shop, Blacksmith, etc). Note: this is used for something else that I (the author) have forgotten.

Building Rush
Used to skip time during building upgrades.

Troop Rush
Used to skip time during troop training.

Tech Rush
Used to skip time during research upgrades.

Soulfire
Soulfire is used to level up dragon abilities and evolve your dragon. Soulfire is gained through chests and the abyss.

Dragonglass
Dragonglass is used to train your dragon and evolve dragon abilities.

Honor
Used to increase rank (up to a point), unlock new buildings, change your race, and buy items (in black market and scroll store). Honor is gained by battling players, completing quests, and robbing resource carts.

City Credit
City Credit is only earned from the city you currently reside in. City Credits do not transfer when you move cities. City Credits are used to collect resources or troops at guard towers. When requesting resources, one gets 30% of the guard tower's resources. This costs 10 City Credits. Requesting troops costs 50 City Credits. IMPORTANT: DO NOT DO THIS! You will get a bunch of bronze troops.

Prosperity
Prosperity is not a normal currency. It cannot be spent and can be thought of as more of a measure. Prosperity is earned from upgrading/building buildings. A certain amount of prosperity is needed to upgrade your city level. Most of the time, you will not have to worry about prosperity if you actually upgrade your buildings.

Linari
Linari is used for many things, including but not limited to shop purchases, buying chests, and transferring realms. Linari can be obtained through login gifts, obelisk milestones, buying it (with actual money), and legendary chests.

Soulbit
Soulbits are used to buy hero chests. Each hero chest requires 10 Soulbits. If you do not have enough Soulbits for a hero chest, you can use Linari

Activity
Activity resets each day. You gain activity by performing certain activity actions. At each 50 activity milestone (up to 350) grants you a chest with predetermined rewards.
