Gems Gem are Infinity Heroes' premium currency that can be purchased directly from the Store. Gems may be used to purchase Medals, Gem Upgrades, Elixir, Logging, Mining and Gauntlet energy, and Card Packs.

Spending Gems

It is generally recommended to increase the "More Gold!" and "More XP!" upgrade in Gem Upgrades to level 5 fairly quickly (total Gem costs can be found here). This gives you an early +20% boost to Gold and XP gains, which can either be spent on additional Gold upgrades or straight up Auto Damage increases.
