Those are some low damage rolls. If the dwarf is still standing and the last attack hits, Wolf will spend a superiority die to make a Menacing Attack to try to frighten him (IC he shouts over the bullets, "This is the beginning of the end, Kriegers!" but it is in Amcaran, so who knows if it means anything to them). It adds (1d8)[2] damage and he has to make a WIS save or is frightened.
