Just wondering if all the skill and combat/fighting calculators work with Old School Runescape as well? I see there is an Old School option on the actual combat calculator but don't see anything like that on other skill calculators. I haven't played since 2010 which is why I'm asking and this use to be my go-to site when I did play. Also, when using the Fighting Calculator after I enter all of the required information, clicking on Tip Me does not show anything.
