Monster Hunter 2 has an improved weapon tree and upgradeable armors. As in all Monster Hunter games, armor pieces can be worn to obtain skills and abilities. A new feature in Monster Hunter 2 is the use of gems. Gems add skill points to complement those added by armor and weapons. Gems are created by combining ore and/or monster parts. Gems can be attached and detached from armor and weapons that have special gem slots.
