Fission is a Rare Skill for The Defect. It removes all Orbs, granting the player 1 Energy and drawing 1 card for each Orb removed this way. When Upgraded, it Evokes the Orbs instead of simply removing them--the difference is that the Orbs triggers their effects. Fission Exhausts on use.

Strategy[]

This card is very powerful when Upgraded, especially in builds that use Capacitor or RunicCapacitor Runic Capacitor to add additional Orb Slots. It draws a lot more cards to use and gives you the Energy you need to fuel them, which can be used to fill your Orb slots back up again.

When combines with Plasma Plasma Orbs, Fission can generate tons of energy.
