Gems
Gems are the standard prize for clearing any level of mode. They are awarded after every mission. The amount awarded varies, as there is a fixed amount after completing a mission, or based on the player's time survived of monsters killed. Gems can be used to train troops or upgrade the player's castle. Ore is the Stellar Wars counterpart of Gems.

Moonstones
Moonstones, which are won from a variety of places, are crucial in improving the player's army. They allow the player to upgrade troop's armor, buy and upgrade spells, hire more mineys, buy more castle elfys, and buying magic touch. Moonstones are somewhat rare, but extremely useful. These sources are one-time only. The counterpart of the Moonstone in Monster Wars is the Soulstone. Stellar Wars' counterpart is the Nova.
