ça vient de là (dans le livre de règles) :
CLOSE Object Action – CLOSE: If this character is holding
an object, make a close attack targeting a single character
and modify damage +1 if the object is light or +2 if the
object is heavy. Immediately after the attack resolves, KO
the object.
RANGE Object Action – RANGE: Range value 6. If this
character is holding an object, make a range attack
targeting a single character that, instead of normal
damage, deals 2 damage if the object is light or 3 damage
if the object is heavy. Immediately after the attack
resolves, KO the object.
These two actions are known as the “object actions.”
Effects looking for an “object attack” identify when a
character makes an attack using either of these actions.
Note that these abilities only allow a character to use an
object in an attack if it can be given either a CLOSE or
RANGE to activate one of the object actions, not anytime
it makes an attack during other actions or special triggered
effects.
Utiliser un objet nécessite une action (close ou range) et HSS ne donne qu'une attaque, toujours pas de close action.
