When exactly do you spend the die to trigger the Flechette Torpedo effect? The timing is pretty important when shooting at a squadron with a scatter token.
I initially assumed this happened during the Resolve Attack Effects step, but it doesn't have a natural home there. It's a "spend" not a "cancel" and so not an obvious Dice Modification. The only dice I can normally "spend" are accuracies. The other option is the Resolve Damage step. The rules say I might need to spend a "die icon" for a critical effect but this isn't a critical effect and squadrons don't normally suffer critical effects.
