I am playing a monk in our Oriental Adventures campaign, and recently we had a situation where another player was grappling a wu jen spell caster. We thought about breaking her neck to quickly get rid of her, but the only mechanic I could think of is
coup de grace, which required her to be unconscious and would take a full round to execute.
Are there any other official mechanics or some interesting house rules which can allow you to kill someone with a grapple, whether one is a monk or not?
Alternatively, I am looking for other ways of having unarmed combatants eliminate opponents in a grapple, not necessarily killing them. Strangling until unconsciousness or other things would be nice too.
