Expert Assistance
If you have 5 or more ranks in a skill you’re using to aid another,
you can grant a higher bonus. For every 10 points your check
result exceeds 10, the circumstance bonus increases by 1. To
determine the circumstance bonus quickly, simply divide the
helper’s check result by 10, round down, and add 1.
At the DM’s option, this rule can also be extended to using
the aid another action in combat to improve an ally’s attack
roll or AC. Any character who has a base attack bonus of +5
or higher can grant a greater bonus on an ally’s attack roll or
AC as described above.
又记错了, 实际上是这样的...投入5点技能点后检定结果每超过10 10点, 就再+1.......比如结果为22的协助, 那么被协助者结果+3, 这样-_-
