A few tips on grinding kinah efficiently

1. Don't carry too much, leave room for found equipment so you can explore for great distances and have more to sell for kinah with each trip.
2. . If you venture out of town in a straight line for exploration, stop exploring when you are at 50% capacity. If you kill everything on the way back, you will be full of items to sell for kinah when you reach town.
3. Stock up on restorative items such as food, bandages, etc. This allows you to grind for kinah longer with each trip, rather than spending all your time traveling.
4. Don't fight more than one monster at a time. If you do, you'll spend more time recovering HP which could have been spent killing monsters for kinah.
5.  Bank your kinah so that you don't loose any as a penalty when you die. There isn't much to buy with kinah in the wilderness anyway, and kinah has weight that can affect your carrying capacity. Banks do not have any kind of surcharge for storing your kinah, so after stocking up for a trip out of town, it's best to deposit all of your kinah for safekeeping.
