don't get killed (er black out XD) seeing as Pokemon can murder you more or less also go back to bagin (security corps npc by the stairs (1F) in HQ he's accessable after your first official mission not your entry mission) to increase your sachet size (even if it gets rather expensive over time) also pick up crafting material in the field and use your crafting kit often so you don't run out of items mid excursion
