The Ineffable Mysteries of Ophion
Skills are being changed to better suit convenience and simplicity. (Like those words belong anywhere in 3.5)
We’re going to use the pathfinder skills system. Most skills are the same, but some have been combined or eliminated. For instance, jump, balance, and a few others have been combined into ‘acrobatics’. You can view the full list here.
Check your class to see if any of your class skills have changed. If your class isn’t listed just use your best judgement. (If your class has jump and balance as class skills, chances are Acrobatics will be a new class skill for them.)
