Leviathan Marties

[Xexamedes]

Is it possible for 2 marties to be generated by the same Leviathan?

The net thrower has a 25% chance to get one, is this chance further modified by luck, and if so who's luck value if the thrower doesnt make enough damage for loot rights?

 

[Basara]

Multiple people in the fight can get a drop, and it will always be the same item for all of the ones getting one.
