Un ours est un super grimpeur dans la limite ou il peut se servir de ses griffes pour grimper. Ici c'est un mur vertical!
DC25 A rough surface, such as a natural rock wall or a brick wall.
"Push" an animal 25
Check: With a successful Climb check, you can advance up, down, or across a slope, wall, or other steep incline (or even across a ceiling, provided it has handholds) at one-quarter your normal speed.
Donc pour monter un mur de 4 étages, il lui faudra 10*4/(40/4) = 4 jets de climb et de animal handling.
