Please note the following house rules** to the Monk.
A Monk's ki strike ability overcomes 5 points of DR/Magic for every 4 levels they have attained.
Starting at 3rd level, a Monk gains a +1 bonus to CMB. At 5th level and every 4 levels thereafter (9th, 13th), this bonus increase by another +1 to a maximum of +5 at 17th level.
Note: This change is solely to make feasible the calculation of CMB for gestalt Monks. For non-gestalt characters, this rule is effectively unchanged from the one in Pathfinder RPG.
