If a character of normal (human) strength receives a dot in the Potence discipline, how much stronger does that actually make him? It gives him an automatic success on Strength checks, but can he bend steel bars? What is his new lifting capacity? The rulebook says:
"Potence enables vampires to leap tremendous distances, lift massive weights and strike opponents with terrifying force. Even the lowest ranks of this power gift the Kindred with physical might beyond mortal bounds."
