Today a place to do lootbag would be a place that drop many not so expensive itens that the knight won't have cap to carry at the end of the hunt. I do not encourage making lootbags of the expensive itens due to risk of losing them.
For lootbags is important to have a place where you can hide your parcel, backpack or bag without people finding it. In the past i used to hunt at Mintwallin and hide the itens on a dead minotaur
that is part of the city and won't perish. You can also hide a bag
behind a tree
or use containers that are part of the place decoration.
For a low level would recommend hunting at Hero Fortress and keeping the Halberts from Vicius Squares
and Plate armors from the bonebeast
.
