Currencies (SF3)

There are three currencies in Shadow Fight 3, though not used often. Coins/gold are obtained by main quests, and gems are obtained by boss battles. Shadow Energy is received by upgrading items via the EXP bar on every piece of equipment.

Each currency is for one main thing. Coins/gold and gems are used for booster packs, while Shadow Energy is used to upgrade items.

Rarity ranges from common to rare.

Coins
Alike gems except for the fact that they are more common, coins are used to purchase booster packs containing items and perks. In Chapter I: Legion, Booster Packs are purchased for 1000 Coins/Gold or [idk] gems. In Chapter II: Dynasty, Booster Packs are purchased for 1500 Coins/Gold or [idk] gems. In Chapter III: Heralds, Booster Packs are purchased for 2000 Gold/Coins (?) or [idk] gems.

Gems
Crimson, diamond shaped gems are usually used for the same reason of coins but more rare. Only won when victorious in boss fights, this precious, rare currency is something for upgrades.

Shadow Energy
Shadow Energy is blue, orbs which of are used to enhance equipment to the next level. These special orbs are enough to make someone rich, just like when Gizmo sold all his Shadow Energy.
