Gaming The Last Story: online Fray mode reward questions.

[hwangtinglee]

I know you can only get the prize weapons in Suppression mode the first time you beat each boss, afterward it'll just be upgrade materials for those weapons, So I'm just wondering if the same deal applies to the Fray mode prize weapon as well (Rose, Coral, etc), that once you get one of those unique weapons, you'll no longer be able to received them as winning prize anymore.
