1. Putting leeches in the shoe slot on your equipment window will work the same as regular shoes except they will not break
2. By finding a fishing spot close to a swamp you're able to have endless amounts of bait for catching your fish and you can cook them over a fire in the same location
3. If you want to make sure that your boat is safe after you log out, put it in a leanto with a bed and then sleep inside that bed. This will mean that the person will need to steal from the leanto to get it, and you can log back on at your water spot.
4. Blocking your house's door with a hearthfire (hold shift when placing the sign to get it in the right position) on the outside will not allow anyone to go inside of your house and steal your things unless they break either the house (high str needed) or your hearthfire (vandalism needed)
