In Diablo II Resurrected, Rockstopper is part of the Sallet category and one of many unique Helms in D2R. It is an item of average size, taking 4 Blocks of space if you want to store it in the inventory or stash. Your character needs to reach at least the Required Level of 31 to carry this item. This Sallet has a Strength Requirement of 43 before it can be used.
The Sallet is the exceptional version of this Helm. It can be upgraded to the elite version by putting it into the Horadric Cube. After hitting the transmute button it will be called Hydraskull. The most basic (normal) version is called Skull Cap.
Note: If this item can have sockets, you might be able to get some runes and get one of the runewords as a result - if you place them in the correct order. Have a look at our builds to find out which items make the most sense for the character you're currently playing.
