A soft cap is a point at which the game specifically begins reducing the effectiveness of a stat. For example, if there was a stat that increased at half effectiveness after 100 (so 180 would actually function as 140), that would be a soft cap. This is as opposed to a hard cap, which completely ignores anything past a certain point. Soft and hard caps are limitations imposed by the game designers; they have nothing to do with "the highest X you can get with this character" (although they can affect that).

Percent magic penetration has no cap. However, mathematically it is impossible for it to ever reach 100%.
