On page 201 of the PF core book under Trip, the second paragraph says, "If your attack exceeds the target's CMB, the target is knocked prone."
On page 199 of the PF core book under Determine Success at the bottom of the first column is says, "If your attack roll equals or exceeds the CMB of the target, your maneuver is a success..."
There maybe a contradiction, typo or the trip attack is actually handled differently.
My question is: When using the trip combat maneuver, does the attacker need to EXCEED or EQUAL the defender's DC?
Thank you.
