For this Advent? None. For if the first weapon is to get a FLB, the event will rerun and you can just farm those mats then.

I doubt they use FULL Grids? They use five Assault weapons (or four Assault weapons and one offensive Soul weapon) for the Phantom weapon bonus.

I mean, more would be better technically, but not really realistic to reach.
