The last session ended mid-combat with much of the party grappled. (Yay Black Tentacles.) They are looking for ways, beyond Dim Door, Grease and Aid Another, for one character to help another get out of a grapple.
One concept that came up is Drag. One PC would be attempting to drag a willing PC out of the area of the grapple. The rules do not seem to support this, although it does make sense.
Does anyone know of optional rules or common house rules (or even official rules that I am overlooking) to let this work?
The common rule you would be over looking is aid another to get out of a grapple.
Personally I would not allow drag or reposition to function, especially not if they attempt to surpress their CMD. It's a hot topic on the board whether one can surpress their CMD against an ally to recieve the benefit of a reposition or drag manuever.
