I recommend having level ranges. the range shall be within 5 levels. If there's no one in the rooms within 5 levels of you it will automaticly turn into ten RuneScape 3 Gold, then 15 or twenty, twenty-five or 30. (if you are not within the range of 30 levels, you most certainly will be penalized,) if there is no one within the same level, they'll inform that there is no one within your level...
