I already created a thread where I talked about the math behind the barding success chance : http://uorforum.com/threads/barding-success-chance-the-real-math.6360/ Now someone was nice enough to convert those formulas into a very nice online calculator: http://www.bitnatter.com/calc/calc.html Please note: This calculator does NOT include the "custom success chance" implemented here as a custom feature since I am unable to investigate the exact mechanics The calculator just does the math for you. It's up to you to interpret the output. If you have questions or additional input please post it here.
Thanks for this - very helpful. I'm probably getting something wrong, but looking at the Balron page in the beastiary, their 'barding difficulty' is 125, which, when put into the calculator, comes out at 115 with a slayer instrument - but the beastiary says the barding difficulty is 100 with a slayer instrument... I'm not sure why there is a discrepancy
