I don't understand why you have energy blast as an extra to be honest...
if you have the stun power as an extra to your strike power, you choose weather you want your power to stun or strike, it doesn't do both. for that you need to take stun seperatlty and have the triggered extra 'when energy blast 1 is used'. Now, if you want to choose between two different forms of energy blast (such as fire and electricity) I would say that requires a power stunt.
to fire more then one energy blast, you need auto fire or Multifire
