Quest Horn - Random or Last Hit? or?

[^Saristian]

After killing golky, who will get the quest Horn? Is there a dropable horn too?

Will it be the party which did the last hit or random participant of the raid?
Or any other mechanics?

[20shizuo]

the quest horn will be  random in the party  who hits the last hit

last hit pt, so if this pt has "fk" it will go to the hiter, if random it will be randomly distributed to one of the "last hitting pt" member
