In Diablo II Resurrected, Witherstring is part of the Hunter's Bow category and one of many unique Bows in D2R. It is a relatively big item, taking 6 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 13 to carry this item. Another limitation is Dexterity, which should be 28 as the very minimum.
Please note that this Weapon is Two-Handed, so your character can not use an additional weapon or shield at the same time. You also need to be carrying Arrows in order to shoot this one.
This is the normal version of this Bow. It can be upgraded to the exceptional version by putting it into the Horadric Cube. After hitting the transmute button it will be called Razor Bow. After that, it can be upgraded even further by repeating the steps and you will receive the Elite Version (Blade Bow).
