So we can protect our possesions a little better. There would be two ways one could get into such chest
- A key (obviously). You get chest's key along with chest upon crafting it and you can make spares in special crafting station. Each key would be good only for chest it was made for.
- Lockpicks. Usage would be either lockpicking minigame or lockpicking with a random chance of success (on failure lockpick would be destroyed).
