Leader wounds and fatigue in SOB

By gran_orco, in Descent: Journeys in the Dark

When a card says "+10 wounds and +2 armor for each level of campaign", which is the right option in silver?:

  • +10 wounds, +4 armor
  • +20 wounds, +4 armor

I would say +20 wounds +4 armor.

and Gold would be +30 wounds +6 armor.

Mind you I can see why it could be interpreted the other way too.

+20/+4 is right.

blah blah adding more words to the form blah blah
