I'm expecting a large amount of "weapon +3" trials for all weapon types for the Lv95 increase update, but I was thinking about Lv99 trials for the maximum power.
My idea was that we could have trials for each elemental trial staff (Agni's, Surya's, etc) that would have all of that element's affinity stats (macc, matk, avatar perpetuation cost, etc) that would all be on a single staff.
The catch would be we would have to have each version of the +3 of said staff, but by turning them all into the crate and completing the trial, it would give us a staff with simply "element affinity +6" or +5 if there are no plans to increase from that of course.
It would be worth the effort, for sure.
