I would need to turn both focus dice to 1.
If I gain the initiative, I'd have know way of summing to 18; but if I lose the initiative, my f(12) could be captured, leaving me with no way to sum to 18.
If I *do* gain the initiative, what should I take? the z(12) feels very dangerous, especially with both focus dice having value 1 after gaining the initiative. On the other hand, if I hope to ever force the (20) to reroll, I have to take out the stinger die.
