Just gonna leave this here

Looks great, but removing the level of the stones should never be an option. That sort of thing is how we got Harbor Bridge farming. Players should be required to actually do league content in red maps if they want to get the rewards for it; allowing players to farm a level 60 area for stones before taking them into a map to use them is a bad idea ripe for exploitation.

Would it though?
It would just save players some time and be a huge qol buff.
If your build can kill lvl 60-70-80 petrified mobs with 4 stones juiced, you surely can zoom and one shot packs there too and farm as fast as anywhere.

No exploits there. Totally worth it.
But if you insist then just add another drop menu on each stone slot to select from a lot of different ilvl stones.
