I have a question regarding the wording for Shock Longbow +1. The card states:
"For your combat check, reveal this card to roll your Dexterity or Ranged die + 1d8+1; you may additionally discard this card to add your unmodified Strength die with the electricity trait. If you aren't proficient with weapons, the difficulty of this check is increased by 4."
Does that increase by 4 for non-weapon proficiency apply only to discarding the card to add your strength die or does that penalty apply anytime the card is used?
