"stave piercing" refers to the equipment that can't actually be used as a stave. This kind of equipment is characterized by providing a large number of spell penetration attributes for heroes. The equipment icon looks like a scepter, so it has the nickname "stave piercing".

Only the pain mask and the virtual staff have the effect of wearing shoes (not including wearing shoes here), so the general usage of wearing staff refers to the virtual staff.

Magic Penetration is a heroic attribute, which can improve the magic damage and attack power of skills, and can ignore part or all of the spell resistance of the target. Each hero's magic penetration base value is 0, and you can improve your attributes through equipment and runes. Some heroic skills are accompanied by the effect of strengthening magic penetration.
