I'm going to expand on my tangential thought to make it more relevant to this convo:
Illicit: Jury-Rigged Energy Cells
3 energy, non-recurring.
During the system phase, you may gain 1 energy to roll an attack die. On a blank, lose 1 energy. Suffer all hit / crit results.
Cannon: Flechette Cannon.
4 die attack
Attack: spend 2 energy. If this attack hits, the defender suffers 1 crit and gains 1 stress. Then cancel all remaining hit/crit results
I'll be honest, I just really love the idea of scum ships going to great lengths to strap a capital class weapon to their spaceship. Like space goblins.
