Do I resolve non-Shadow "Revealed" effects when revealing a Shadow card?
Step 3 of the Combat phase in the rulebook:


  
  Resolve shadow effect. The active player flips that enemy’s shadow card faceup and resolves any shadow effect that card might have.
  


You only use the shadow part of the card when resolving shadow cards. When you flip a card like The Necromancer's Reach where there is no shadow effect, you are in luck.
