- A "Bury" project for certain movable containers.
- When you start it, the project asks for "instructions". You enter then a short text like "Thirty steps east from the marked coconut tree, then twenty steps north and ten steps uphill." It can be also a riddle answer or whatever you like.
This text is the treasure "key" that will be matched later to dig it.
- When the project is finished, the container isn't listed anymore in that location.
- When you start a treasure dig project (1 day or so) with the shovel, you are asked for the instructions; capitals shouldn't matter, but the text must be exact. You don't get a warning if it's wrong.
- The container is lost when you dig it back. So you aren't going to abuse it as a regular storage.
- If the treasure isn't recovered, it will be revealed after... fifty years or so.
What I like most of the idea is that the necessary step to recover the treasure would be knowledge, either from mouth to ear or written. Imagine what would mean defeating or jailing that old pirate captain.
