Taking Damage vs. Dealt Damage

Another Captain Cosmic-related question: must a card take damage in order for it to have been dealt damage.  For example:

Captain Cosmic has Cosmic Crest ("Captain Cosmic and all Construct cards are immune to Energy Damage") and Vitality Conduit (Construct; "Play this card next to a Target.  Whenever this card is dealt damage, That Target regains 2 HP.") in play.  Grand Warlord Voss plays Gene-Bound Ion-Lancer which deals 2 Energy Damage to Vitality Conduit.  Vitality Conduit is immune to Energy Damage and takes no damage.  Does Captain Cosmic get to heal 2 HP?

No. For damage to be dealt, hp needs to go down.

Thanks again.
