It doesn't have to be an easy skill check to accomplish. However, pushing that poor old woman to her doom is thematically close to the fate of hags living in forests in common fairy tales. Hansel and Gretel being the obvious comparison. It's like the situation with Dror Ragzlin at the Goblin Camp when he sits below that giant statue. I should at least have an skill check option to push that statue over. Maybe it does not kill him and just injures him giving me a benefit in combat, but failure in the skill check alerts him and others to what I am doing.
