If a character has no power at the start of an attack. They chose to trigger the leadership for this attack. The attack would give them power. Can they chose to take a damage from the leadership so they don't have to spend any of the power they would gain? Does the power spending requirement of the leadership happen at the after the attack is resolved step so the controlling character can chose the order in which it happens? Thank you in advance for the clarification!

Thank you very much!

If a model with scientific hubris attacks and uses the leadership "My Cabal is only for the Strong" to treat a failure as a crit does this count as a crit for the purposes of the power gains from Scientific hubris?
