Function Syntax

float [monster] appearance_rates(location place )

float [monster] appearance_rates(location place ,boolean queue )

  • place is the adventuring location to parse
  • The optional parameter queue is false if not included.

Returns a map, keyed by monster, with the appearance rate percentages as decimal values (ie a 30% rate monster has a value of 30.0). Bosses, semirare encounters, and other one-time-only monsters have a value of 0.0; ultra-rare monsters have a negative value (the actual value varies; test by looking for value < 0, not value == -1). Does not account for combat rate modifiers, olfaction, etc.

If there is a chance of non-combat encounters, that will be listed as the chance of encountering $monster[none].

If queue is true, then the monsters currently in the adventuring queue will be considered when determining the likelihood of future encounters. This is better for a real prediction of what monster will actually occur next while not considering the queue is better for modeling theoretical situations.

Simple Example

Prints the encounters in a zone and their rates of appearing.

foreach mob, freq in appearance_rates($location[Dungeon of Doom])
   switch {
   case mob == $monster[none]:
      if(freq > 0) print("Frequency of non-combats: "+ freq + "%");
   case freq > 0:
      print("Frequency of " + mob + ": " + freq + "%");
   case freq == 0:
      print("Frequency of " + mob + ": Boss (one time encounter) or semirare encounter.");
   case freq < 0:
      print("Frequency of " + mob + ": Ultra-rare!");
      print("Frequency of " + mob + ": Unknown");
