Can you gain or spend Power in the middle of an Attack to add more dice to it, or use a before-attack skill twice?

Question

Accepted Answer

No. Power is spent to add dice before rolling, once per Attack, and a skill that triggers before attacking is a single step at the start. It cannot be repeated, and Power gained mid-attack cannot add dice to that attack. Doctor Doom's Blue skill is used before the attack, not partway through.
