Item description:

only tested it for around 10 minutes but you can pop most of the grindiest trophies.

Go to the gov office and talk to the reward ranking vendor in the middle (Blonde Girl) and you will get Ranker and Top Dog.

Go and kill a few enemies and you will get the weapon proficiency trophies.

In your room use the blue thing next to the item box and load a new customization data then level up your stats again to get OP Trophy after that buy all the skills again to get Collector trophy.

Put Kirito in your party and go kill a few enemies to get the Best Friends Forever trophy.

If you kill enough enemies to level up 1 more time you may get the Level 100 trophy but i didnt have time to test it.

Replay 1 Unique enemy quest to get reaper unfortunately you cant replay Hunting quests or Treasure quests so you wont be able to get those with this save unless you go into NG+ and see if beating one of the quests in NG+ will pop the trophy i didnt have time to test this myself.

Im sure theres a few more trophies you can get but this is all i tested.
