Editing When to carry a rosto (section)

== A little math ==

A [[Rostogol Stone]] protects your belongings in case of death, but the rosto then disappears from your inventory.

Whether carrying a rosto pays off primarily depends on the worth of your belongings. Furthermore, it depends on the probability with which you might be able to regain your death bag if you do not have a rosto.

The cost of a rosto is about 33kgc. Let say you have a 33% chance to regain your death bag, then you should wear a rosto, if the stuff in your inventory (excluding the rosto) is worth more than 99 kgc:

 33kgc
      / 0.5 (because chance for dropping an item is 50%)
      /(1-0.33) probability that you do regain your DB is assumed to be 33%
 --------------
 99kgc

If you have the [[Careful Guy Perk]] the second value is to be adjusted to 0.4, which yields a result that is 20% higher.

The chance for regaining your death bag has to be adjusted depending on the situation. For example in invasions, there is additional risk:
* being bag jumped, since it is likely that other players are around when you die
* you cannot get back to the place because the invasion creatures keep killing you
* the bag disappears early because there are many drop bags on the map

Thus for invasions, we could assume the worst case and calculate

 33kgc
      / 0.5 (because chance for dropping an item is 50%)
      /(1-0) probability that you do regain your DB is assumed to be 0%
 --------------
 66kgc

as threshold limit when to carry a rosto.

In contrast, when you are with friends, it is very likely that they can save your DB, so we get

 33kgc
      / 0.5 (because chance for dropping an item is 50%)
      /(1-1) probability that you do regain your DB is assumed to be 100%
 --------------
 infinity

In other words, don't carry a rosto when you are with trustworthy friends unless of course in instances where it will knock you out. And players have been known to be bag jumped in instances so even instances are not completely safe.
