Strategy

Ball lightning, for its low cost, is incredibly effective. The damage it provides can help with groups of enemies that are very close to the base. Its long duration also makes it possible to clear 2 short waves (like Jet} in a row with just one usage of this ability. Because of its highly concentrated damage, Ball lightning specifically has a x0.01 damage multiplier against bosses to make them harder to kill. Metaphor is an exception here, receiving the standard 10% damage from this ability.
