a1bert Thank you very much! The same applies to hero abilities? I can use Smugglers Luck once a round for reroll or additional draw of supply cards?

I have got three questions. When attacking as a hero or empire henchman, after rolling dices can I spend multiple surges on the same ability? For example in this case, use 2 surges for Pierce 4? The same case for stormtrooper, 2 surges for 4 dmg? Also does bleed apply to all attacks made by nexu? Do I understand it correctly, that I can use it every round? Empire attachment cards can be used once per Mission, or they are single use?
