Some spell effects you can use to do a combat maneuver on an opponent like grappling or bullrushing. Think of telekinesis or forceful hand.
The CMB is often described, but not the CMD to escape or counter the maneuver.
What is the CMD to escape a telekinesis grapple? Or bullrush against a forceful hand etc? Is it the Wizard's? That seems counterintuitive since I think my mental telekinesis is stronger than my thin frail body with CMD below the 20s.
I noticed that the CMD to escape black tentacles is 10+its CMB. Should that be the general rule to use for spell effects like this?
