Afterglow effect - option to disable or to move it to the weapon only?

[Nyarlko]

actually, trial of magian dumps that concept as long as your not doing the current trial at that time, same weapon, different trial.

however you are right, the "Rare" status prevents weapons of the same name being attained twice, a +1 or +2 must be added to the name in order to change it to something else

The Trial weapons that can be duped are only tagged EX. You can't have a lv85 Twashtar and a 119III one is my understanding.
