DM: You come to a cliff. If you look, you do not see the ground but you can see a series of columns that emerge from the obscurity of the cliff.
Ranger: I throw a rope to tie it to a column and climb it.
(He launch the dice. He get it. All PCs climb the rope)
Wizard (me): I can’t climb. I haven’t strength enough. I will die!!!
DM: Launch the dice. You can get a good result.
Wizard (me): No! I don’t want! Can I use intelligence to climb?
Wizard (me): Why not? I have read a lot of books about climbing and I am a very smart woman. I know perfectly all the theory about climbing. That deserves a bonus.
