Toppling Spell Feat check, Do I roll d20 too?

[fuel gun]

Dumb question: do I roll a d20 and add my caster level and Int bonus to the check versus the opponent's CMD to see if they are tripped or do I just get my caster level and Int bonus? Thanks!

your CMB will be your CL + INt bonus. To this you roll a d20 just like anyone else would to get your total.

I just started Carrion Crown with a wizard. Took this feat with traits that let me reduce metamagic level by 1 and anothe to increase CL by 1. So far no trips though.
Thinking of trying with spiritual weapon aswell.
