Another rules question. Suppose a monster with two modes of attack, for example these two ones I'm making up on the fly:
(melee basic attack) Longsword +10 VS AC, 1d8+6 damage
(melee) Flury of slashes: The monster makes two longsword attacks against the same or different opponents.
The question is if those two longsword attacks the monster mkaes with his Flurry melee attack count as a single attack (since they are part of the Flurry ability) or not (since they seem to be two discrete longsword attacks). If the monster attacks a defender with one longsword slash and another party member with the second, would it trigger mark punishment, for example?
