Diablo 2 can only replace the substrate if the number of washing holes is incorrect. In this generation of games, weapons, shields, helmets and armor will all have a groove.

Except for some magic, bright gold equipment, suits or hidden gold equipment, white equipment will turn gray once it has grooves. Players can not only add grooves to the designated equipment through the tasks in the fifth act, but also make holes in the equipment by using the synthesis formula of Hradik squares.

Diablo 2 jewelry is similar to a gem to some extent, but it will bring some magic equipment after inserting equipment. In addition, jewelry will have some random magical properties, allowing you to design various combinations for your groove equipment to fully show everyone's personality. Outstanding jewelry has three magical attributes. Before your jewels are put into the groove, their magical properties must be identified by the identification scroll or Kane.
