3 attack range 1-2
4 energy
Attack: [lock] Spend 1 energy
After this attack, you may perform this attack against a different target at range 0-1 of the defender, ignoring the [lock] requirement.
Now, let's say there are 2 ships in my arc at range 2, flying close to each other.
I fire my cluster missile, spend an energy, then the ability of the missiles kicks in. I can spend another energy to perform this attack again, but against another target. I spend the energy and perform the attack. However, since its the same attack, it has the same ability, so it kicks in again, and now I can attack the original ship again... And repeat.
So in 1 turn, I can perform 4 3 dice attacks. Admittedly, it is limited by the situations... But There is no reason why I couldn't clear a swarm with this, and some lucky dicerolls. right?
