From EQ2i, the EverQuest II wiki

Crushing is a skill used by all Crushing Weapons. This skill is of particular importance to Mages, Priests and Fighters. This skill demonstrates how well you use hammers, maces, staves, and even your own fists and affects the chance that you will be successful when landing a blow with a weapon that uses the crushing skill.

The Crushing weapon you can use depends on your adventure level and class, but not on your Crushing skill:

• Category:Crushing (Equipment) - Equipment that modifies the Crushing skill.
• Category:Crushing Skill Adornments - Adornments that modifies the Crushing skill.
• Crushing Weapons - Weapons that depend upon mastery of the Crushing skill.
