Stash Value Tips

1.Start farming early. Two months of passive accumulation beats one week of desperate grinding.

2.Don't sell expedition items early. Snow Globes (7K RC), Bombardier Cells (3K RC) add up.

3.Hoard high-value items. Epic weapons in your stash count toward value at departure.

4.Run Stella Montis the last week. Medical Research 100K+ per run.

5.Use Looting Mk.2 augment. Safe pockets protect your most valuable finds.

6.Your wallet counts. Coins at departure add to stash value.

7.Craft before departing. A crafted weapon is worth more than its raw materials.
