You have a feeling about how things are going to turn out. You can roll your skill check before declaring an action.
Roll two dice at the start of your turn. These dice will apply to your action this turn. If you declare the action to be within your profession, you may use your professional reroll before choosing the action. If the action you choose has variable difficulty (pumping Engines or Helm maneuvers) you may finish the skill check with reroll pools and Luck before declaring the action.
When it is all said and done, you may choose an action instead that doesn't involve a die roll (such as moving, drawing a weapon, or using “calm”) but any spent pool and special abilities are still spent. You may use this ability a maximum of once per Phase.
