смысл ноги в том, что, насколько я понял из вординга, модель получает 6+ сейв, который кидается после провала армор сейва и который по сути не являятся армор сейвом => минусы к армор сейвам от некоторых оружий на него не действуют.
А вот насчет руки-крюка - действительно, сниму ее кэпу)
вординг:
Peg Leg (one per model)
Any Pirate suffering a Leg Wound or Smashed
Leg can opt to have his ruined leg replaced with
a stout wooden peg leg. This will reduce his
Movement (and maximum possible Movement
characteristic) by -1, but offers a chance that
stray hits will strike the leg instead. This gives
him a special saving throw of 6+, which can be
taken whenever he fails any other saving throws
allowed against any wounding shooting or
hand-to-hand hits. This save is not modified,
and can be used even if no saving throw is
normally allowed. A new pirate joining the
warband, either during initial warband creation
or as a new hire, may also start out with a Peg
Leg. If the wearer gets a Leg Wound or Smashed
Leg in further battles, these can be ignored on a
roll of 4+ as the hit was taken by the Peg Leg
instead.
