Gem, also known as ruby, is the premium currency in Shadow Fight 2, which are accepted as a mode of exchange throughout the game. They are also the only currency used at Underworld. Gems can be used for every item for which coins can be used. In addition to that, Gems can buy special items in the game which are not purchaseable using coins. This is especially true of those items which are readily enchanted by the game. But Gems are secondary in the sense that it is more difficult to obtain than gold coins/platinums/credits and players can easily get out of gems because the amount won/bought is quite limited.
Advantages
Gems have some distinct advantages over coins/platinums/credits. They are:
- Gems can buy all items which coins can. In addition gems can also buy super items that are usually enchanted and deal higher damage than normal ones which are not available for purchase using coins.
- When buying or upgrading using gems, the game does not set a delivery time and the items are ready to use immediately after their purchase.
- The items that only can be bought with gems also can only be upgraded to a higher level by using gems. This also applies to challengers' weapons, special events items, boss weapons, and the Set of Monk.
- The energy bar can be fully restored using gems(x5).
- Gems can be used to skip the delivery time that of items are bought or upgraded using coins.
- The Perk Tree can be reset using 35 gems.
- Gems allow the players rematches after losing to a Challenger.
- Gems can be used to buy ticket for Ascension. Players can buy 10 tickets for 80 gems.
- After winning a stage in Ascension, gems allow the players to spin the lottery again after their first spin.
In Underworld, they can be used to:
- Purchase Charges of Darkness.
- Buy keys for bosses.
- Skip waiting time when fighting a boss.
- Skip the timer for daily quests.
- Buy packs and special chests.
- Create a clan.
