Power Cards

Equipping Power Cards allows the player to use abilities and increase Alien's stats on the gameboard. There are 5 colors: red, blue, purple, green and orange. Equipping 3 cards of the same color grants additional stats (+10% HP, Energy, Melee damage, Pod damage and Arrow damage, respectively). There are 4 rarities in a Power Card: Common, Rare, Epic an Legendary. Cards of higher rarity have better and more stats.

Cards can be Upgraded, using Color Sparks and Coins. Each upgrade increases that card's stats value. This stat boost can be controlled: the more to the right the moving bars are when the Upgrade button is pushed, the greater the boost is. To avoid losing stat boosts, a Bolt can be added to the Upgrade fee; this ensures the Upgrade will give the maximum boost for that level. Apart from that, at levels 5, 10 and 15, new stats are unlocked.

Once a card reaches level 20, it must be Evolved in order to unlock further upgrades, up to level 40. Evolution of a card is a process that has to be done only once, and requires a variable amount of Big Color Sparks, Bolts and Coins.

Once a card is evolved, the Rune system is unlocked. Runes are equipped to the Power Card, granting important stat boosts to them. At level 20 (inmediately after Evolving the card), three different random Runes are given; the player has to choose one among them to be equipped to the card. This process can be done again in levels 30 and 40, which means that a card can have up to 3 Runes equipped. A Rune can be rerolled by paying 25 Gems; the card loses the selected Rune and three different ones are shown again. Runes cannot be transfered between cards.

Imbue Power Cards with Supreme Sparks to maximize card stats. Every card can be Imbued 20 times. however, this limit can be extended via Upgrade. At levels 20, 30 and 40, the card's Imbue capacity increases in 10 points every time, which means that a level 40 card can be Imbued up to 50 times.

Disenchant Power Cards to destroy them and get Color Sparks in exchange. The amount of Color Sparks obtained depends on the level and the rarity of the disenchanted card.

Note that some cards "Transform Alien". These cards cannot be used at the same time (however, they can be in the same Deck in order to use the most appropriate one in different situations):
