One of my friends had an issue with the Mesmerist archtype Cult Master, the Fanatical Stare ability displays as a +4 attack bonus even at level 1, should be +1 to begin with then reaching +4 after 6th, 12th and 18th level. I might have found the issue to fix it in my own files in oa_abilities_class.lst line 1464 changing the 4 to a 1. Not sure if thats the correct way to go but thought I'd mention it.
A simple fix is changing ‘max’ to ‘min’ take the lower of the two values.
Ah thats good to know!
