Thanks, xanaqui42. I know what happened to my revision. It was located on the first link you provided. Didn't realize at the time there were three locations were the Arcane experience table was located. I've now revised the other two locations.
My revision corrected the formula expressing the probability:
Channeling I: 25 - XP possessed (minimum 1%
Channeling II: 35 - XP/2 possessed (minimum 2%)
Channeling III: 40 - XP/3 possessed (minimum 3%)
Or with the Arcane trait:
Channeling I: 30 - XP possessed (minimum 1%)
Channeling II: 45 - XP/2 possessed (minimum 2%)
Channeling III: 55 - XP/3 possessed (minimum 3%)
Was:
Channeling I: 25% - 1%/XP possessed (minimum 1%)
Channeling II: 35% - 1%/(2 XP) possessed (minimum 2%)
Channeling III: 40% - 1%/(3 XP) possessed (minimum 3%)
Or with the Arcane trait:
Channeling I: 30% - 1%/XP possessed (minimum 1%)
Channeling II: 45% - 1%/(2 XP) possessed (minimum 2%)
Channeling III: 55% - 1%/(3 XP) possessed (minimum 3%)
