I Would had just done what 1.0 had spirit bond the weapon.

1.special bonus if you spiritbond your weapon on duty finder.
2. SB the weapon on high level dungeon IE coil and hard and extreme primals
3. SB weapon on fates a % per zone
4. Just kill this amount of mobs per day per zone.
5. I even tempted to try speedruns on dungeons for an item. I had fun with them on 1.0.

This blind fate grinding is not challenging is just boring and annoying I manage to get my first atma in 5 hours of grinding fates receiving a gold medal every time. Come On SE 11 had pretty good fun ways to upgrade your weapon you could see the work and it was team based oriented.
